cd989e1192 spi: imx: mx51-ecspi: Reinstate low-speed CONFIGREG delay 
[ Upstream commit 135cbd378eab336da15de9c84bbb22bf743b38a5 ]

Since 00b80ac935 ("spi: imx: mx51-ecspi: Move some initialisation to
prepare_message hook."), the MX51_ECSPI_CONFIG write no longer happens
in prepare_transfer hook, but rather in prepare_message hook, however
the MX51_ECSPI_CONFIG delay is still left in prepare_transfer hook and
thus has no effect. This leads to low bus frequency operation problems
described in 6fd8b8503a ("spi: spi-imx: Fix out-of-order CS/SCLK
operation at low speeds") again.

Move the MX51_ECSPI_CONFIG write delay into the prepare_message hook
as well, thus reinstating the low bus frequency fix.

Fixes: 00b80ac935 ("spi: imx: mx51-ecspi: Move some initialisation to prepare_message hook.")

9c645a020b spi: mediatek: Fix fifo transfer 
commit 0d5c3954b35eddff0da0436c31e8d721eceb7dc2 upstream.

Commit 3a70dd2d0503 ("spi: mediatek: fix fifo rx mode") claims that
fifo RX mode was never handled, and adds the presumably missing code
to the FIFO transfer function. However, the claim that receive data
was not handled is incorrect. It was handled as part of interrupt
handling after the transfer was complete. The code added with the above
mentioned commit reads data from the receive FIFO before the transfer
is started, which is wrong. This results in an actual transfer error
on a Hayato Chromebook.

Remove the code trying to handle receive data before the transfer is
started to fix the problem.

03258515c9 spi: stm32h7: fix full duplex irq handler handling 
[ Upstream commit e4a5c19888a5f8a9390860ca493e643be58c8791 ]

In case of Full-Duplex mode, DXP flag is set when RXP and TXP flags are
set. But to avoid 2 different handlings, just add TXP and RXP flag in
the mask instead of DXP, and then keep the initial handling of TXP and
RXP events.
Also rephrase comment about EOTIE which is one of the interrupt enable
bits. It is not triggered by any event.

113ce8c504 spi: cadence: Correct initialisation of runtime PM again 
[ Upstream commit 56912da7a68c8356df6a6740476237441b0b792a ]

The original implementation of RPM handling in probe() was mostly
correct, except it failed to call pm_runtime_get_*() to activate the
hardware. The subsequent fix, 734882a8bf ("spi: cadence: Correct
initialisation of runtime PM"), breaks the implementation further,
to the point where the system using this hard IP on ZynqMP hangs on
boot, because it accesses hardware which is gated off.

Undo 734882a8bf ("spi: cadence: Correct initialisation of runtime
PM") and instead add missing pm_runtime_get_noresume() and move the
RPM disabling all the way to the end of probe(). That makes ZynqMP
not hang on boot yet again.

844ab04b62 spi: imx: add a check for speed_hz before calculating the clock 
[ Upstream commit 4df2f5e1372e9eec8f9e1b4a3025b9be23487d36 ]

When some drivers use spi to send data, spi_transfer->speed_hz is
not assigned. If spidev->max_speed_hz is not assigned as well, it
will cause an error in configuring the clock.
Add a check for these two values before configuring the clock. An
error will be returned when they are not assigned.

c43082d284 spi: spi-sun6i: Fix chipselect/clock bug 
[ Upstream commit 0d7993b234c9fad8cb6bec6adfaa74694ba85ecb ]

The current sun6i SPI implementation initializes the transfer too early,
resulting in SCK going high before the transfer. When using an additional
(gpio) chipselect with sun6i, the chipselect is asserted at a time when
clock is high, making the SPI transfer fail.

This is due to SUN6I_GBL_CTL_BUS_ENABLE being written into
SUN6I_GBL_CTL_REG at an early stage. Moving that to the transfer
function, hence, right before the transfer starts, mitigates that
problem.

08d0aa16a1 spi: Avoid undefined behaviour when counting unused native CSs 
[ Upstream commit f60d7270c8a3d2beb1c23ae0da42497afa3584c2 ]

ffz(), that has been used to count unused native CSs,
might cause undefined behaviour when called against ~0U.
To fix that, open code it with ffs(~value) - 1.

db5a7e22c9 spi: Allow to have all native CSs in use along with GPIOs 
[ Upstream commit dbaca8e56ea3f23fa215f48c2d46dd03ede06e02 ]

The commit 7d93aecdb5 ("spi: Add generic support for unused native cs
with cs-gpios") excludes the valid case for the controllers that doesn't
need to switch native CS in order to perform the transfer, i.e. when

  0		native
  ...		...
  <n> - 1	native
  <n>		GPIO
  <n> + 1	GPIO
  ...		...

where <n> defines maximum of native CSs supported by the controller.

To allow this, bail out from spi_get_gpio_descs() conditionally for
the controllers which explicitly marked with SPI_MASTER_GPIO_SS.

when it creates a new SPI device. This means when the device is
registered the fwnode is NULL and the check in device_add which sets
the fwnode->dev pointer is skipped. This wasn't previously an issue,
however these two patches:

commit 4731210c09f5 ("gpiolib: Bind gpio_device to a driver to enable
fw_devlink=on by default")
commit ced2af419528 ("gpiolib: Don't probe gpio_device if it's not the
primary device")

Added some code to the GPIO core which relies on using that
fwnode->dev pointer to determine if a driver is bound to the fwnode
and if not bind a stub GPIO driver. This means the GPIO providers
behind SPI will get both the expected driver and this stub driver
causing the stub driver to fail if it attempts to request any pin
configuration. For example on my system:

madera-pinctrl madera-pinctrl: pin gpio5 already requested by madera-pinctrl; cannot claim for gpiochip3
madera-pinctrl madera-pinctrl: pin-4 (gpiochip3) status -22
madera-pinctrl madera-pinctrl: could not request pin 4 (gpio5) from group aif1  on device madera-pinctrl
gpio_stub_drv gpiochip3: Error applying setting, reverse things back
gpio_stub_drv: probe of gpiochip3 failed with error -22

The firmware node on the device created by the GPIO framework is set
through the of_node pointer hence things generally actually work,
however that fwnode->dev is never set, as the check was skipped at
device_add time. This fix appears to match how the I2C subsystem
handles the same situation.

[ Upstream commit d38fa9a155b2829b7e2cfcf8a4171b6dd3672808 ]

In U-boot side, an issue has been encountered when QSPI source clock is
running at low frequency (24 MHz for example), waiting for TCF bit to be
set didn't ensure that all data has been send out the FIFO, we should also
wait that BUSY bit is cleared.

To prevent similar issue in kernel driver, we implement similar behavior
by always waiting BUSY bit to be cleared.

In zynq_qspi_probe function, when enable the device clock is done,
the return of all the functions should goto the clk_dis_all label.

If num_cs is not right then this should return a negative error
code but currently it returns success.

82a8ffba54 spi: bcm2835: Fix out-of-bounds access with more than 4 slaves 
commit 13817d466eb8713a1ffd254f537402f091d48444 upstream.

Commit 571e31fa60 ("spi: bcm2835: Cache CS register value for
->prepare_message()") limited the number of slaves to 3 at compile-time.
The limitation was necessitated by a statically-sized array prepare_cs[]
in the driver private data which contains a per-slave register value.

The commit sought to enforce the limitation at run-time by setting the
controller's num_chipselect to 3:  Slaves with a higher chipselect are
rejected by spi_add_device().

However the commit neglected that num_chipselect only limits the number
of *native* chipselects.  If GPIO chipselects are specified in the
device tree for more than 3 slaves, num_chipselect is silently raised by
of_spi_get_gpio_numbers() and the result are out-of-bounds accesses to
the statically-sized array prepare_cs[].

As a bandaid fix which is backportable to stable, raise the number of
allowed slaves to 24 (which "ought to be enough for anybody"), enforce
the limitation on slave ->setup and revert num_chipselect to 3 (which is
the number of native chipselects supported by the controller).
An upcoming for-next commit will allow an arbitrary number of slaves.

fa05ba6196 spi: Cleanup on failure of initial setup 
[ Upstream commit 2ec6f20b33eb4f62ab90bdcd620436c883ec3af6 ]

Commit c7299fea6769 ("spi: Fix spi device unregister flow") changed the
SPI core's behavior if the ->setup() hook returns an error upon adding
an spi_device:  Before, the ->cleanup() hook was invoked to free any
allocations that were made by ->setup().  With the commit, that's no
longer the case, so the ->setup() hook is expected to free the
allocations itself.

I've identified 5 drivers which depend on the old behavior and am fixing
them up hereinafter: spi-bitbang.c spi-fsl-spi.c spi-omap-uwire.c
spi-omap2-mcspi.c spi-pxa2xx.c

Importantly, ->setup() is not only invoked on spi_device *addition*:
It may subsequently be called to *change* SPI parameters.  If changing
these SPI parameters fails, freeing memory allocations would be wrong.
That should only be done if the spi_device is finally destroyed.
I am therefore using a bool "initial_setup" in 4 of the affected drivers
to differentiate between the invocation on *adding* the spi_device and
any subsequent invocations: spi-bitbang.c spi-fsl-spi.c spi-omap-uwire.c
spi-omap2-mcspi.c

In spi-pxa2xx.c, it seems the ->setup() hook can only fail on spi_device
addition, not any subsequent calls.  It therefore doesn't need the bool.

It's worth noting that 5 other drivers already perform a cleanup if the
->setup() hook fails.  Before c7299fea6769, they caused a double-free
if ->setup() failed on spi_device addition.  Since the commit, they're
fine.  These drivers are: spi-mpc512x-psc.c spi-pl022.c spi-s3c64xx.c
spi-st-ssc4.c spi-tegra114.c

(spi-pxa2xx.c also already performs a cleanup, but only in one of
several error paths.)

0c4d4de2da spi: Don't have controller clean up spi device before driver unbind 
[ Upstream commit 27e7db56cf3dffd302bd7ddfacb1d405cf671a2a ]

When a spi device is unregistered and triggers a driver unbind, the
driver might need to access the spi device. So, don't have the
controller clean up the spi device before the driver is unbound. Clean
up the spi device after the driver is unbound.

06e84ea1f4 spi: sprd: Add missing MODULE_DEVICE_TABLE 
[ Upstream commit 7907cad7d07e0055789ec0c534452f19dfe1fc80 ]

MODULE_DEVICE_TABLE is used to extract the device information out of the
driver and builds a table when being compiled. If using this macro,
kernel can find the driver if available when the device is plugged in,
and then loads that driver and initializes the device.

4b8b7bc3a7 spi: Fix spi device unregister flow 
[ Upstream commit c7299fea67696db5bd09d924d1f1080d894f92ef ]

When an SPI device is unregistered, the spi->controller->cleanup() is
called in the device's release callback. That's wrong for a couple of
reasons:

1. spi_dev_put() can be called before spi_add_device() is called. And
   it's spi_add_device() that calls spi_setup(). This will cause clean()
   to get called without the spi device ever being setup.

2. There's no guarantee that the controller's driver would be present by
   the time the spi device's release function gets called.

3. It also causes "sleeping in atomic context" stack dump[1] when device
   link deletion code does a put_device() on the spi device.

Fix these issues by simply moving the cleanup from the device release
callback to the actual spi_unregister_device() function.

f5da0820c5 spi: Assume GPIO CS active high in ACPI case 
[ Upstream commit 6b69546912a57ff8c31061f98e56383cc0beffd3 ]

Currently GPIO CS handling, when descriptors are in use, doesn't
take into consideration that in ACPI case the default polarity
is Active High and can't be altered. Instead we have to use the
per-chip definition provided by SPISerialBus() resource.

fe6921e3b8 spi: spi-fsl-dspi: Fix a resource leak in an error handling path 
commit 680ec0549a055eb464dce6ffb4bfb736ef87236e upstream.

'dspi_request_dma()' should be undone by a 'dspi_release_dma()' call in the
error handling path of the probe function, as already done in the remove
function

18593eb97f Revert "spi: Fix use-after-free with devm_spi_alloc_*" 
This reverts commit c7fabe372a which is
commit 794aaf01444d4e765e2b067cba01cc69c1c68ed9 upstream as it breaks
the kabi.

This should not be needed for android devices as they do not remove SPI
devices under normal operation.

5980a3b9c9 spi: spi-zynqmp-gqspi: return -ENOMEM if dma_map_single fails 
[ Upstream commit 126bdb606fd2802454e6048caef1be3e25dd121e ]

The spi controller supports 44-bit address space on AXI in DMA mode,
so set dma_addr_t width to 44-bit to avoid using a swiotlb mapping.
In addition, if dma_map_single fails, it should return immediately
instead of continuing doing the DMA operation which bases on invalid
address.

This fixes the following crash which occurs in reading a big block
from flash:

[  123.633577] zynqmp-qspi ff0f0000.spi: swiotlb buffer is full (sz: 4194304 bytes), total 32768 (slots), used 0 (slots)

[ Upstream commit a2c5bedb2d55dd27c642c7b9fb6886d7ad7bdb58 ]

When handling op->addr, it is using the buffer "tmpbuf" which has been
freed. This will trigger a use-after-free KASAN warning. Let's use
temporary variables to store op->addr.val and op->cmd.opcode to fix
this issue.

fa3a26b437 spi: spi-zynqmp-gqspi: fix hang issue when suspend/resume 
[ Upstream commit 799f923f0a66a9c99f0a3eaa078b306db7a8b33a ]

After calling platform_set_drvdata(pdev, xqspi) in probe, the return
value of dev_get_drvdata(dev) is a pointer to struct zynqmp_qspi but
not struct spi_controller. A wrong structure type passing to the
functions spi_controller_suspend/resume will hang the system.

And we should check the return value of spi_controller_suspend, if
an error is returned, return it to PM subsystem to stop suspend.

Also, GQSPI_EN_MASK should be written to GQSPI_EN_OFST to enable
the spi controller in zynqmp_qspi_resume since it was disabled in
zynqmp_qspi_suspend before.

24159580ab spi: spi-zynqmp-gqspi: fix clk_enable/disable imbalance issue 
[ Upstream commit c6bdae08012b2ca3e94f3a41ef4ca8cfe7c9ab6f ]

The clks "pclk" and "ref_clk" are enabled twice during the probe. The
first time is in the function zynqmp_qspi_probe and the second time is
in zynqmp_qspi_setup_op which is called by devm_spi_register_controller.
Then calling zynqmp_qspi_remove (rmmod this module) to disable these clks
will trigger a warning as below:

[  309.124604] Unpreparing enabled qspi_ref
[  309.128641] WARNING: CPU: 1 PID: 537 at drivers/clk/clk.c:824 clk_core_unprepare+0x108/0x110

Since pm_runtime works now, clks can be enabled/disabled by calling
zynqmp_runtime_suspend/resume. So we don't need to enable these clks
explicitly in zynqmp_qspi_setup_op. Remove them to fix this issue.

And remove clk enabling/disabling in zynqmp_qspi_resume because there is
no spi transfer operation so enabling ref_clk is redundant meanwhile pclk
is not disabled for it is shared with other peripherals.

Furthermore replace clk_enable/disable with clk_prepare_enable and
clk_disable_unprepare in runtime_suspend/resume functions.

[ Upstream commit 41d310930084502433fcb3c4baf219e7424b7734 ]

When starting a read operation, we should call zynqmp_qspi_setuprxdma
first to set xqspi->mode according to xqspi->bytes_to_receive and
to calculate correct xqspi->dma_rx_bytes. Then in the function
zynqmp_qspi_fillgenfifo, generate the appropriate command with
operating mode and bytes to transfer, and fill the GENFIFO with
the command to perform the read operation.

Calling zynqmp_qspi_fillgenfifo before zynqmp_qspi_setuprxdma will
result in incorrect transfer length and operating mode. So change
the calling order to fix this issue.

3144696667 spi: spi-zynqmp-gqspi: transmit dummy circles by using the controller's internal functionality 
[ Upstream commit 8ad07d79bd56a531990a1a3f3f1c0eb19d2de806 ]

There is a data corruption issue that occurs in the reading operation
(cmd:0x6c) when transmitting common data as dummy circles.

The gqspi controller has the functionality to send dummy clock circles.
When writing data with the fields [receive, transmit, data_xfer] = [0,0,1]
to the Generic FIFO, and configuring the correct SPI mode, the controller
will transmit dummy circles.

So let's switch to hardware dummy cycles transfer to fix this issue.

[ Upstream commit a16bff68b75fd082d36aa0b14b540bd7a3ebebbd ]

When Ctrl+C occurs during the process of zynqmp_qspi_exec_op, the function
wait_for_completion_interruptible_timeout will return a non-zero value
-ERESTARTSYS immediately. This will disrupt the SPI memory operation
because the data transmitting may begin before the command or address
transmitting completes. Use wait_for_completion_timeout to prevent
the process from being interruptible.

We can't rely on the contents of the devres list during

time we perform devres_find() for devm_spi_release_controller. This
causes devices registered with devm_spi_alloc_{master,slave}() to be
mistakenly identified as legacy, non-devm managed devices and have their
reference counters decremented below 0.

Fix by switching over to the new devm_spi_alloc_master() helper which
keeps the private data accessible until the driver has unbound.

0390f6f1d0 spi: stm32: drop devres version of spi_register_master 
[ Upstream commit 8d559a64f00b59af9cc02b803ff52f6e6880a651 ]

A call to spi_unregister_master() triggers calling remove()
for all the spi devices binded to the spi master.

Some spi device driver requires to "talk" with the spi device
during the remove(), e.g.:
- a LCD panel like drivers/gpu/drm/panel/panel-lg-lg4573.c
  will turn off the backlighting sending a command over spi.
This implies that the spi master must be fully functional when
spi_unregister_master() is called, either if it is called
explicitly in the master's remove() code or implicitly by the
devres framework.

Devres calls devres_release_all() to release all the resources
"after" the remove() of the spi master driver (check code of
__device_release_driver() in drivers/base/dd.c).
If the spi master driver has an empty remove() then there would
be no issue; the devres_release_all() will release everything
in reverse order w.r.t. probe().
But if code in spi master driver remove() disables the spi or
makes it not functional (like in this spi-stm32), then devres
cannot be used safely for unregistering the spi master and the
binded spi devices.

Replace devm_spi_register_master() with spi_register_master()
and add spi_unregister_master() as first action in remove().

c5aa9ea54a spi: sync up initial chipselect state 
[ Upstream commit d347b4aaa1a042ea528e385d9070b74c77a14321 ]

When initially probing the SPI slave device, the call for disabling an
SPI device without the SPI_CS_HIGH flag is not applied, as the
condition for checking whether or not the state to be applied equals the
one currently set evaluates to true.

This however might not necessarily be the case, as the chipselect might
be active.

Add a force flag to spi_set_cs which allows to override this
early exit condition. Set it to false everywhere except when called
from spi_setup to sync up the initial CS state.

Fixes commit d40f0b6f2e ("spi: Avoid setting the chip select if we don't
need to")

pm_runtime_get_sync will increment pm usage counter even it failed.
Forgetting to putting operation will result in reference leak here.
Fix it by replacing it with pm_runtime_resume_and_get to keep usage
counter balanced.

[ Upstream commit a23faea76d4cf5f75decb574491e66f9ecd707e7 ]

Call spi_master_get() holds the reference count to master device, thus
we need an additional spi_master_put() call to reduce the reference
count, otherwise we will leak a reference to master.

This commit fix it by removing the unnecessary spi_master_get().

[ Upstream commit ffb597b2bd3cd78b9bfb68f536743cd46dbb2cc4 ]

This removes the assignment of setup and cleanup functions for the ath79
target. Assigning the setup-method will lead to 'setup_transfer' not
being assigned in spi_bitbang_init. Because of this, performing any
TX/RX operation will lead to a kernel oops.

Also drop the redundant cleanup assignment, as it's also assigned in
spi_bitbang_init.

[ Upstream commit 19e2132174583beb90c1bd3e9c842bc6d5c944d1 ]

spi-bitbang has to call the chipselect function on the ath79 SPI driver
in order to communicate with the SPI slave device, as the ath79 SPI
driver has three dedicated chipselect lines but can also be used with
GPIOs for the CS lines.

commit 102e9d1936569d43f55dd1ea89be355ad207143c upstream.

pm_runtime usage_count counter is not well managed.
pm_runtime_put_autosuspend callback drops the usage_counter but this
one has never been increased. Add pm_runtime_get_sync callback to bump up
the usage counter. It is also needed to use pm_runtime_force_suspend and
pm_runtime_force_resume APIs to handle properly the clock.

422806f8d2 spi: cadence: set cqspi to the driver_data field of struct device 
commit ea94191e584b146878f0b7fd4b767500d7aae870 upstream.

When initialize cadence qspi controller, it is need to set cqspi
to the driver_data field of struct device, because it will be
used in function cqspi_remove/suspend/resume(). Otherwise, there
will be a crash trace as below when invoking these finctions.

Fixes: 31fb632b5d ("spi: Move cadence-quadspi driver to drivers/spi/")

2314d50617 spi: stm32: make spurious and overrun interrupts visible 
[ Upstream commit c64e7efe46b7de21937ef4b3594d9b1fc74f07df ]

We do not expect to receive spurious interrupts so rise a warning
if it happens.

RX overrun is an error condition that signals a corrupted RX
stream both in dma and in irq modes. Report the error and
abort the transfer in either cases.

1f8a887593 spi: fsl: invert spisel_boot signal on MPC8309 
commit 9d2aa6dbf87af89c13cac2d1b4cccad83fb14a7e upstream.

Commit 7a2da5d7960a ("spi: fsl: Fix driver breakage when SPI_CS_HIGH
is not set in spi->mode") broke our MPC8309 board by effectively
inverting the boolean value passed to fsl_spi_cs_control. The
SPISEL_BOOT signal is used as chipselect, but it's not a gpio, so
we cannot rely on gpiolib handling the polarity.

Adapt to the new world order by inverting the logic here. This does
assume that the slave sitting at the SPISEL_BOOT is active low, but
should that ever turn out not to be the case, one can create a stub
gpiochip driver controlling a single gpio (or rather, a single "spo",
special-purpose output).

86f5b09369 spi: Skip zero-length transfers in spi_transfer_one_message() 
[ Upstream commit b306320322c9cfaa465bc2c7367acf6072b1ac0e ]

With the introduction of 26751de25d ("spi: bcm2835: Micro-optimise
FIFO loops") it has become apparent that some users might initiate
zero-length SPI transfers. A fact the micro-optimization omitted, and
which turned out to cause crashes[1].

Instead of changing the micro-optimization itself, use a bigger hammer
and skip zero-length transfers altogether for drivers using the default
transfer_one_message() implementation.

231d8c46b1 spi: dw: Avoid stack content exposure 
[ Upstream commit 386f771aad15dd535f2368b4adc9958c0160edd4 ]

Since "data" is u32, &data is a "u32 *" type, which means pointer math
will move in u32-sized steps. This was meant to be a byte offset, so
cast &data to "char *" to aim the copy into the correct location.

Seen with -Warray-bounds (and found by Coverity):

d8d37cdde2 spi: cadence-quadspi: Abort read if dummy cycles required are too many 
[ Upstream commit ceeda328edeeeeac7579e9dbf0610785a3b83d39 ]

The controller can only support up to 31 dummy cycles. If the command
requires more it falls back to using 31. This command is likely to fail
because the correct number of cycles are not waited upon. Rather than
silently issuing an incorrect command, fail loudly so the caller can get
a chance to find out the command can't be supported by the controller.

ebe992a1ea BACKPORT: UPSTREAM: amba: Make the remove callback return void 
All amba drivers return 0 in their remove callback. Together with the
driver core ignoring the return value anyhow, it doesn't make sense to
return a value here.

Change the remove prototype to return void, which makes it explicit that
returning an error value doesn't work as expected. This simplifies changing
the core remove callback to return void, too.

Commit 766c6b63aa ("spi: fix client driver breakages when using GPIO

As now we fully rely on gpiolib for handling the polarity of
chip selects, the driver shall not alter the GPIO value anymore
when SPI_CS_HIGH is not set in spi->mode.

501e1875da spi: fix the divide by 0 error when calculating xfer waiting time 
[ Upstream commit 6170d077bf92c5b3dfbe1021688d3c0404f7c9e9 ]

The xfer waiting time is the result of xfer->len / xfer->speed_hz. This
patch makes the assumption of 100khz xfer speed if the xfer->speed_hz is
not assigned and stays 0. This avoids the divide by 0 issue and ensures
a reasonable tolerant waiting time.

[ Upstream commit ede090f5a438e97d0586f64067bbb956e30a2a31 ]

This patch fixes the return value for altera_spi_txrx. It should return
1 for interrupt transfer mode, and return 0 for polling transfer mode.

The altera_spi_txrx() implements the spi_controller.transfer_one
callback. According to the spi-summary.rst, the transfer_one should
return 0 when transfer is finished, return 1 when transfer is still in
progress.

commit a590370d918fc66c62df6620445791fbe840344a upstream.

if cur_bpw <= 8 and xfer_len < 4 then the value of fthlv will be 1 and
SPI registers content may have been lost.

* If SPI data register is accessed as a 16-bit register and DSIZE <= 8bit,
  better to select FTHLV = 2, 4, 6 etc

* If SPI data register is accessed as a 32-bit register and DSIZE > 8bit,
  better to select FTHLV = 2, 4, 6 etc, while if DSIZE <= 8bit,
  better to select FTHLV = 4, 8, 12 etc

c75a66726d spi: spi-geni-qcom: Fix geni_spi_isr() NULL dereference in timeout case 
commit 4aa1464acbe3697710279a4bd65cb4801ed30425 upstream.

In commit 7ba9bdcb91 ("spi: spi-geni-qcom: Don't keep a local state
variable") we changed handle_fifo_timeout() so that we set
"mas->cur_xfer" to NULL to make absolutely sure that we don't mess
with the buffers from the previous transfer in the timeout case.

Unfortunately, this caused the IRQ handler to dereference NULL in some
cases.  One case:

  CPU0                           CPU1
  ----                           ----
                                 setup_fifo_xfer()
                                  geni_se_setup_m_cmd()
                                 <hardware starts transfer>
                                 <transfer completes in hardware>
                                 <hardware sets M_RX_FIFO_WATERMARK_EN in m_irq>
                                 ...
                                 handle_fifo_timeout()
                                  spin_lock_irq(mas->lock)
                                  mas->cur_xfer = NULL
                                  geni_se_cancel_m_cmd()
                                  spin_unlock_irq(mas->lock)

  geni_spi_isr()
   spin_lock(mas->lock)
   if (m_irq & M_RX_FIFO_WATERMARK_EN)
    geni_spi_handle_rx()
     mas->cur_xfer NULL dereference!

tl;dr: Seriously delayed interrupts for RX/TX can lead to timeout
handling setting mas->cur_xfer to NULL.

Let's check for the NULL transfer in the TX and RX cases and reset the
watermark or clear out the fifo respectively to put the hardware back
into a sane state.

NOTE: things still could get confused if we get timeouts all the way
through handle_fifo_timeout() and then start a new transfer because
interrupts from the old transfer / cancel / abort could still be
pending.  A future patch will help this corner case.

a885713b0c spi: spi-geni-qcom: Fail new xfers if xfer/cancel/abort pending 
commit 690d8b917bbe64772cb0b652311bcd50908aea6b upstream.

If we got a timeout when trying to send an abort command then it means
that we just got 3 timeouts in a row:

1. The original timeout that caused handle_fifo_timeout() to be
   called.
2. A one second timeout waiting for the cancel command to finish.
3. A one second timeout waiting for the abort command to finish.

SPI is clocked by the controller, so nothing (aside from a hardware
fault or a totally broken sequencer) should be causing the actual
commands to fail in hardware.  However, even though the hardware
itself is not expected to fail (and it'd be hard to predict how we
should handle things if it did), it's easy to hit the timeout case by
simply blocking our interrupt handler from running for a long period
of time.  Obviously the system is in pretty bad shape if a interrupt
handler is blocked for > 2 seconds, but there are certainly bugs (even
bugs in other unrelated drivers) that can make this happen.

Let's make things a bit more robust against this case.  If we fail to
abort we'll set a flag and then we'll block all future transfers until
we have no more interrupts pending.

c6dd62c14b spi: dw-bt1: Fix undefined devm_mux_control_get symbol 
commit 7218838109fef61cdec988ff728e902d434c9cc5 upstream.

I mistakenly added the select attributes to the SPI_DW_BT1_DIRMAP config
instead of having them defined in SPI_DW_BT1. If the kernel doesn't have
the MULTIPLEXER and MUX_MMIO configs manually enabled and the
SPI_DW_BT1_DIRMAP config hasn't been selected, Baikal-T1 SPI device will
always fail to be probed by the driver. Fix that and the error reported by
the test robot:

>> ld.lld: error: undefined symbol: devm_mux_control_get
   >>> referenced by spi-dw-bt1.c
   >>> spi/spi-dw-bt1.o:(dw_spi_bt1_sys_init) in archive drivers/built-in.a

by moving the MULTIPLEXER/MUX_MMIO configs selection to the SPI_DW_BT1
config.

785eee857d spi: atmel-quadspi: Fix AHB memory accesses 
commit cac8c821059639b015586abf61623c62cc549a13 upstream.

Following error was seen when mounting a 16MByte ubifs:
UBIFS error (ubi0:0 pid 1893): check_lpt_type.constprop.6: invalid type (15) in LPT node type

QSPI_IFR.TFRTYP was not set correctly. When data transfer is enabled
and one wants to access the serial memory through AHB in order to:
 - read in the serial memory, but not a memory data, for example
   a JEDEC-ID, QSPI_IFR.TFRTYP must be written to '0' (both sama5d2
   and sam9x60).
 - read in the serial memory, and particularly a memory data,
   TFRTYP must be written to '1' (both sama5d2 and sam9x60).
 - write in the serial memory, but not a memory data, for example
   writing the configuration or the QSPI_SR, TFRTYP must be written
   to '2' for sama5d2 and to '0' for sam9x60.
 - write in the serial memory in particular to program a memory data,
   TFRTYP must be written to '3' for sama5d2 and to '1' for sam9x60.

Fix the setting of the QSPI_IFR.TFRTYP field.

671ad53ff3 spi: mt7621: Don't leak SPI master in probe error path 
commit 46b5c4fb87ce8211e0f9b0383dbde72c3652d2ba upstream.

If the calls to device_reset() or devm_spi_register_controller() fail on
probe of the MediaTek MT7621 SPI driver, the spi_controller struct is
erroneously not freed.  Fix by switching over to the new
devm_spi_alloc_master() helper.

Additionally, there's an ordering issue in mt7621_spi_remove() wherein
the spi_controller is unregistered after disabling the SYS clock.
The correct order is to call spi_unregister_controller() *before* this
teardown step because bus accesses may still be ongoing until that
function returns.

All of these bugs have existed since the driver was first introduced,
so it seems fair to fix them together in a single commit.

commit 24f7033405abe195224ec793dbc3d7a27dec0b98 upstream.

Commit 702b15cb9712 ("spi: mt7621: fix missing clk_disable_unprepare()
on error in mt7621_spi_probe") sought to disable the SYS clock on probe
errors, but only did so for 2 of 3 potentially failing calls:  The clock
needs to be disabled on failure of devm_spi_register_controller() as
well.

Moreover, the commit purports to fix a bug in commit cbd66c626e ("spi:
mt7621: Move SPI driver out of staging") but in reality the bug has
existed since the driver was first introduced.

0c2867db23 spi: gpio: Don't leak SPI master in probe error path 
commit 7174dc655ef0578877b0b4598e69619d2be28b4d upstream.

If the call to devm_spi_register_master() fails on probe of the GPIO SPI
driver, the spi_master struct is erroneously not freed:

After allocating the spi_master, its reference count is 1.  The driver
unconditionally decrements the reference count on unbind using a devm
action.  Before calling devm_spi_register_master(), the driver
unconditionally increments the reference count because on success,
that function will decrement the reference count on unbind.  However on
failure, devm_spi_register_master() does *not* decrement the reference
count, so the spi_master is leaked.

The issue was introduced by commits 8b797490b4 ("spi: gpio: Make sure
spi_master_put() is called in every error path") and 79567c1a32 ("spi:
gpio: Use devm_spi_register_master()"), which sought to plug leaks
introduced by 9b00bc7b90 ("spi: spi-gpio: Rewrite to use GPIO
descriptors") but missed this remaining leak.

The situation was later aggravated by commit d3b0ffa1d7 ("spi: gpio:
prevent memory leak in spi_gpio_probe"), which introduced a

ea923e7278 spi: fsl: fix use of spisel_boot signal on MPC8309 
commit 122541f2b10897b08f7f7e6db5f1eb693e51f0a1 upstream.

Commit 0f0581b24b ("spi: fsl: Convert to use CS GPIO descriptors")
broke the use of the SPISEL_BOOT signal as a chip select on the
MPC8309.

pdata->max_chipselect, which becomes master->num_chipselect, must be
initialized to take into account the possibility that there's one more
chip select in use than the number of GPIO chip selects.

bbba6b7a53 spi: ar934x: Don't leak SPI master in probe error path 
commit 236924ee531d6251c8d10e9177b7742a60534ed5 upstream.

If the call to devm_spi_register_controller() fails on probe of the
Qualcomm Atheros AR934x/QCA95xx SPI driver, the spi_controller struct is
erroneously not freed.  Fix by switching over to the new
devm_spi_alloc_master() helper.

Moreover, the controller's clock is enabled on probe but not disabled if
any of the subsequent probe steps fail.

Finally, there's an ordering issue in ar934x_spi_remove() wherein the
clock is disabled even though the controller is not yet unregistered.
It is unregistered after ar934x_spi_remove() by the devres framework.
As long as it is not unregistered, SPI transfers may still be ongoing
and disabling the clock may break them.  It is not possible to use
devm_spi_register_controller() in this case, so move to the non-devm
variant.

All of these bugs have existed since the driver was first introduced,
so it seems fair to fix them together in a single commit.

ddbed6d027 spi: fix resource leak for drivers without .remove callback 
[ Upstream commit 440408dbadfe47a615afd0a0a4a402e629be658a ]

Consider an spi driver with a .probe but without a .remove callback (e.g.
rtc-ds1347). The function spi_drv_probe() is called to bind a device and
so dev_pm_domain_attach() is called. As there is no remove callback
spi_drv_remove() isn't called at unbind time however and so calling
dev_pm_domain_detach() is missed and the pm domain keeps active.

To fix this always use both spi_drv_probe() and spi_drv_remove() and
make them handle the respective callback not being set. This has the
side effect that for a (hypothetical) driver that has neither .probe nor
remove the clk and pm domain setup is done.

spi: dw: Fix spi registration for controllers overriding CS 
When SPI DW memory ops support was introduced, there was a check for
excluding controllers which supplied their own CS function. Even so,
the mem_ops pointer is *always* presented to the SPI core.

This causes the SPI core sanity check in spi_controller_check_ops() to
refuse registration, since a mem_ops pointer is being supplied without
an exec_op member function.

The end result is failure of the SPI DW driver on sparx5 and similar
platforms.

The fix in the core SPI DW driver is to avoid presenting the mem_ops
pointer if the exec_op function is not set.

spi: spi-nxp-fspi: fix fspi panic by unexpected interrupts 
Given the case that bootloader(such as UEFI)'s FSPI driver might not
handle all interrupts before loading kernel, those legacy interrupts
would assert immidiately once kernel's FSPI driver enable them. Further,
if it was FSPI_INTR_IPCMDDONE, the irq handler nxp_fspi_irq_handler()
would call complete(&f->c) to notify others. However, f->c might not be
initialized yet at that time, then cause kernel panic.

Of cause, we should fix this issue within bootloader. But it would be
better to have this pacth to make dirver more robust (by clearing all
interrupt status bits before enabling interrupts).

spi: Take the SPI IO-mutex in the spi_setup() method 
I've discovered that due to the recent commit 49d7d695ca ("spi: dw:
Explicitly de-assert CS on SPI transfer completion") a concurrent usage of
the spidev devices with different chip-selects causes the "SPI transfer
timed out" error. The root cause of the problem has turned to be in a race
condition of the SPI-transfer execution procedure and the spi_setup()
method being called at the same time. In particular in calling the
spi_set_cs(false) while there is an SPI-transfer being executed. In my
case due to the commit cited above all CSs get to be switched off by
calling the spi_setup() for /dev/spidev0.1 while there is an concurrent
SPI-transfer execution performed on /dev/spidev0.0. Of course a situation
of the spi_setup() being called while there is an SPI-transfer being
executed for two different SPI peripheral devices of the same controller
may happen not only for the spidev driver, but for instance for MMC SPI +
some another device, or spi_setup() being called from an SPI-peripheral
probe method while some other device has already been probed and is being
used by a corresponding driver...

Of course I could have provided a fix affecting the DW APB SSI driver
only, for instance, by creating a mutual exclusive access to the set_cs
callback and setting/clearing only the bit responsible for the
corresponding chip-select. But after a short research I've discovered that
the problem most likely affects a lot of the other drivers:
- drivers/spi/spi-sun4i.c - RMW the chip-select register;
- drivers/spi/spi-rockchip.c - RMW the chip-select register;
- drivers/spi/spi-qup.c - RMW a generic force-CS flag in a CSR.
- drivers/spi/spi-sifive.c - set a generic CS-mode flag in a CSR.
- drivers/spi/spi-bcm63xx-hsspi.c - uses an internal mutex to serialize
  the bus config changes, but still isn't protected from the race
  condition described above;
- drivers/spi/spi-geni-qcom.c - RMW a chip-select internal flag and set the
  CS state in HW;
- drivers/spi/spi-orion.c - RMW a chip-select register;
- drivers/spi/spi-cadence.c - RMW a chip-select register;
- drivers/spi/spi-armada-3700.c - RMW a chip-select register;
- drivers/spi/spi-lantiq-ssc.c - overwrites the chip-select register;
- drivers/spi/spi-sun6i.c - RMW a chip-select register;
- drivers/spi/spi-synquacer.c - RMW a chip-select register;
- drivers/spi/spi-altera.c - directly sets the chip-select state;
- drivers/spi/spi-omap2-mcspi.c - RMW an internally cached CS state and
  writes it to HW;
- drivers/spi/spi-mt65xx.c - RMW some CSR;
- drivers/spi/spi-jcore.c - directly sets the chip-selects state;
- drivers/spi/spi-mt7621.c - RMW a chip-select register;

I could have missed some drivers, but a scale of the problem is obvious.
As you can see most of the drivers perform an unprotected
Read-modify-write chip-select register modification in the set_cs callback.
Seeing the spi_setup() function is calling the spi_set_cs() and it can be
executed concurrently with SPI-transfers exec procedure, which also calls
spi_set_cs() in the SPI core spi_transfer_one_message() method, the race
condition of the register modification turns to be obvious.

To sum up the problem denoted above affects each driver for a controller
having more than one chip-select lane and which:
1) performs the RMW to some CS-related register with no serialization;
2) directly disables any CS on spi_set_cs(dev, false).
* the later is the case of the DW APB SSI driver.

The controllers which equipped with a single CS theoretically can also
experience the problem, but in practice will not since normally the
spi_setup() isn't called concurrently with the SPI-transfers executed on
the same SPI peripheral device.

In order to generically fix the denoted bug I'd suggest to serialize an
access to the controller IO by taking the IO mutex in the spi_setup()
callback. The mutex is held while there is an SPI communication going on
on the SPI-bus of the corresponding SPI-controller. So calling the
spi_setup() method and disabling/updating the CS state within it would be
safe while there is no any SPI-transfers being executed. Also note I
suppose it would be safer to protect the spi_controller->setup() callback
invocation too, seeing some of the SPI-controller drivers update a HW
state in there.

spi: dw: Set transfer handler before unmasking the IRQs 
It turns out the IRQs most like can be unmasked before the controller is
enabled with no problematic consequences. The manual doesn't explicitly
state that, but the examples perform the controller initialization
procedure in that order. So the commit da8f58909e ("spi: dw: Unmask IRQs
after enabling the chip") hasn't been that required as I thought. But
anyway setting the IRQs up after the chip enabling still worth adding
since it has simplified the code a bit. The problem is that it has
introduced a potential bug. The transfer handler pointer is now
initialized after the IRQs are enabled. That may and eventually will cause
an invalid or uninitialized callback invocation. Fix that just by
performing the callback initialization before the IRQ unmask procedure.

Merge series "Use-after-free be gone" from Lukas Wunner <lukas@wunner.de>: 
Here's my proposal to fix the use-after-free bugs reported by
Sascha Hauer and Florian Fainelli:

I scrutinized all SPI drivers in the v5.10 tree:

* There are 9 drivers with a use-after-free in the ->remove() hook
  caused by accessing driver private data after spi_unregister_controller().

* There are 8 drivers which leak the spi_controller in the ->probe()
  error path because of a missing spi_controller_put().

I'm introducing devm_spi_alloc_master/slave() which automatically
calls spi_controller_put() on ->remove().  This fixes both classes
of bugs while at the same time reducing code amount and complexity
in the ->probe() hook.

I propose that spi_controller_unregister() should no longer release
a reference on the spi_controller.  Instead, drivers need to either
do it themselves or use one of the devm functions introduced herein.
The vast majority of drivers can be converted to the devm functions.
See the commit message of patch [1/4] for the rationale and details.

Enclosed are patches for 3 Broadcom drivers.
Patches for the other drivers are on this branch:
https://github.com/l1k/linux/commits/spi_fixes

@Florian Fainelli:  Could you verify that there are no KASAN splats or
leaks with these patches?  Unfortunately I do not have any SPI-capable
hardware at my disposal right now, so can only compile-test.  You may
want to augment spi_controller_release() with a printk() to log when
the spi_controller is freed.

@Mark Brown:  Patches [2/4] to [4/4] reference the SHA-1 of patch [1/4]
in their stable tags.  Because the hash is unknown to me until you apply
the patch, I've used "123456789abc" as a placeholder.  You'll have to
replace the hash if/when applying.  Alternatively, only apply patch [1/4]
and I'll repost the other patches with the hash fixed up.

Thanks!

spi: lpspi: Fix use-after-free on unbind 
Normally the last reference on an spi_controller is released by
spi_unregister_controller().  In the case of the i.MX lpspi driver,
the spi_controller is registered with devm_spi_register_controller(),
so spi_unregister_controller() is invoked automatically after the driver
has unbound.

However the driver already releases the last reference in
fsl_lpspi_remove() through a gratuitous call to spi_master_put(),
causing a use-after-free when spi_unregister_controller() is
subsequently invoked by the devres framework.

Fix by dropping the superfluous spi_master_put().

spi: bcm-qspi: Fix use-after-free on unbind 
bcm_qspi_remove() calls spi_unregister_master() even though
bcm_qspi_probe() calls devm_spi_register_master().  The spi_master is
therefore unregistered and freed twice on unbind.

Moreover, since commit 0392727c26 ("spi: bcm-qspi: Handle clock probe
deferral"), bcm_qspi_probe() leaks the spi_master allocation if the call
to devm_clk_get_optional() fails.

Fix by switching over to the new devm_spi_alloc_master() helper which
keeps the private data accessible until the driver has unbound and also
avoids the spi_master leak on probe.

While at it, fix an ordering issue in bcm_qspi_remove() wherein
spi_unregister_master() is called after uninitializing the hardware,
disabling the clock and freeing an IRQ data structure.  The correct
order is to call spi_unregister_master() *before* those teardown steps
because bus accesses may still be ongoing until that function returns.

spi: Introduce device-managed SPI controller allocation 
SPI driver probing currently comprises two steps, whereas removal
comprises only one step:

    spi_alloc_master()
    spi_register_controller()

    spi_unregister_controller()

That's because spi_unregister_controller() calls device_unregister()
instead of device_del(), thereby releasing the reference on the
spi_controller which was obtained by spi_alloc_master().

An SPI driver's private data is contained in the same memory allocation
as the spi_controller struct.  Thus, once spi_unregister_controller()
has been called, the private data is inaccessible.  But some drivers
need to access it after spi_unregister_controller() to perform further
teardown steps.

Introduce devm_spi_alloc_master() and devm_spi_alloc_slave(), which
release a reference on the spi_controller struct only after the driver
has unbound, thereby keeping the memory allocation accessible.  Change
spi_unregister_controller() to not release a reference if the
spi_controller was allocated by one of these new devm functions.

The present commit is small enough to be backportable to stable.
It allows fixing drivers which use the private data in their ->remove()
hook after it's been freed.  It also allows fixing drivers which neglect
to release a reference on the spi_controller in the probe error path.

Long-term, most SPI drivers shall be moved over to the devm functions
introduced herein.  The few that can't shall be changed in a treewide
commit to explicitly release the last reference on the controller.
That commit shall amend spi_unregister_controller() to no longer release
a reference, thereby completing the migration.

As a result, the behaviour will be less surprising and more consistent
with subsystems such as IIO, which also includes the private data in the
allocation of the generic iio_dev struct, but calls device_del() in
iio_device_unregister().

spi: fsi: Fix transfer returning without finalizing message 
In the case that the SPI mux isn't set, the transfer_one_message
function returns without finalizing the message. This means that
the transfer never completes, resulting in hung tasks and an
eventual kernel panic. Fix it by finalizing the transfer in this
case.

spi: fix client driver breakages when using GPIO descriptors 
Commit f3186dd876 ("spi: Optionally use GPIO descriptors for CS GPIOs")
introduced the optional use of GPIO descriptors for chip selects.

A side-effect of this change: when a SPI bus uses GPIO descriptors,
all its client devices have SPI_CS_HIGH set in spi->mode. This flag is
required for the SPI bus to operate correctly.

This unfortunately breaks many client drivers, which use the following
pattern to configure their underlying SPI bus:

static int client_device_probe(struct spi_device *spi)
{
	...
	spi->mode = SPI_MODE_0;
	spi->bits_per_word = 8;
	err = spi_setup(spi);
	..
}

In short, many client drivers overwrite the SPI_CS_HIGH bit in
spi->mode, and break the underlying SPI bus driver.

This is especially true for Freescale/NXP imx ecspi, where large
numbers of spi client drivers now no longer work.

Proposed fix:
-------------
When using gpio descriptors, depend on gpiolib to handle CS polarity.
Existing quirks in gpiolib ensure that this is handled correctly.

Existing gpiolib behaviour will force the polarity of any chip-select
gpiod to active-high (if 'spi-active-high' devicetree prop present) or
active-low (if 'spi-active-high' absent). Irrespective of whether
the gpio is marked GPIO_ACTIVE_[HIGH|LOW] in the devicetree.

Loose ends:
-----------
If this fix is applied:
- is commit 138c9c32f0
  ("spi: spidev: Fix CS polarity if GPIO descriptors are used")
  still necessary / correct ?

spi: dw: Add Baikal-T1 SPI Controller glue driver 
Baikal-T1 is equipped with three DW APB SSI-based MMIO SPI controllers.
Two of them are pretty much normal: with IRQ, DMA, FIFOs of 64 words
depth, 4x CSs, but the third one as being a part of the Baikal-T1 System
Boot Controller has got a very limited resources: no IRQ, no DMA, only a
single native chip-select and Tx/Rx FIFO with just 8 words depth
available. In order to provide a transparent initial boot code execution
the Boot SPI controller is also utilized by an vendor-specific IP-block,
which exposes an SPI flash direct mapping interface. Since both direct
mapping and SPI controller normal utilization are mutual exclusive only
one of these interfaces can be used to access an external SPI slave
device. That's why a dedicated mux is embedded into the System Boot
Controller. All of that is taken into account in the Baikal-T1-specific DW
APB SSI glue driver implemented by means of the DW SPI core module.

spi: dw: Add poll-based SPI transfers support 
A functionality of the poll-based transfer has been removed by
commit 1ceb09717e98 ("spi: dw: remove cs_control and poll_mode members
from chip_data") with a justification that "there is no user of one
anymore". It turns out one of our DW APB SSI core is synthesized with no
IRQ line attached and the only possible way of using it is to implement a
poll-based SPI transfer procedure. So we have to get the removed
functionality back, but with some alterations described below.

First of all the poll-based transfer is activated only if the DW SPI
controller doesn't have an IRQ line attached and the Linux IRQ number is
initialized with the IRQ_NOTCONNECTED value. Secondly the transfer
procedure is now executed with a delay performed between writer and reader
methods. The delay value is calculated based on the number of data words
expected to be received on the current iteration. Finally the errors
status is checked on each iteration.

spi: dw: Introduce max mem-ops SPI bus frequency setting 
In some circumstances the current implementation of the SPI memory
operations may occasionally fail even though they are executed in the
atomic context. This may happen if the system bus is relatively slow in
comparison to the SPI bus frequency, or there is a concurrent access to
it, which makes the MMIO-operations occasionally stalling before
push-pulling data from the DW APB SPI FIFOs. These two problems we've
discovered on the Baikal-T1 SoC. In order to fix them we have no choice
but to set an artificial limitation on the SPI bus speed.

Note currently this limitation will be only applicable for the memory
operations, since the standard SPI core interface is implemented with an
assumption that there is no problem with the automatic CS toggling.

spi: dw: Add memory operations support 
Aside from the synchronous Tx-Rx mode, which has been utilized to create
the normal SPI transfers in the framework of the DW SSI driver, DW SPI
controller supports Tx-only and EEPROM-read modes. The former one just
enables the controller to transmit all the data from the Tx FIFO ignoring
anything retrieved from the MISO lane. The later mode is so called
write-then-read operation: DW SPI controller first pushes out all the data
from the Tx FIFO, after that it'll automatically receive as much data as
has been specified by means of the CTRLR1 register. Both of those modes
can be used to implement the memory operations supported by the SPI-memory
subsystem.

The memory operation implementation is pretty much straightforward, except
a few peculiarities we have had to take into account to make things
working. Since DW SPI controller doesn't provide a way to directly set and
clear the native CS lane level, but instead automatically de-asserts it
when a transfer going on, we have to make sure the Tx FIFO isn't empty
during entire Tx procedure. In addition we also need to read data from the
Rx FIFO as fast as possible to prevent it' overflow with automatically
fetched incoming traffic. The denoted peculiarities get to cause even more
problems if DW SSI controller is equipped with relatively small FIFO and
is connected to a relatively slow system bus (APB) (with respect to the
SPI bus speed). In order to workaround the problems for as much as it's
possible, the memory operation execution procedure collects all the Tx
data into a single buffer and disables the local IRQs to speed the
write-then-optionally-read method up.

Note the provided memory operations are utilized by default only if
a glue driver hasn't provided a custom version of ones and this is not
a DW APB SSI controller with fixed automatic CS toggle functionality.

spi: dw: Add generic DW SSI status-check method 
The DW SSI errors handling method can be generically implemented for all
types of the transfers: IRQ, DMA and poll-based ones. It will be a
function which checks the overflow/underflow error flags and resets the
controller if any of them is set. In the framework of this commit we make
use of the new method to detect the errors in the IRQ- and DMA-based SPI
transfer execution procedures.

By design of the currently available native set_cs callback, the CS
de-assertion will be done only if it's required by the corresponding

spi: dw: Refactor IRQ-based SPI transfer procedure 
Current IRQ-based SPI transfer execution procedure doesn't work well at
the final stage of the execution. If all the Tx data is sent out (written
to the Tx FIFO) but there is some data left to receive, the Tx FIFO Empty
IRQ will constantly happen until all of the requested inbound data is
received. Though for a short period of time, but it will make the system
less responsive. In order to fix that let's refactor the SPI transfer
execution procedure by taking the Rx FIFO Full IRQ into account. We'll read
and write SPI transfer data each time the IRQ happens as before. If all
the outbound data is sent out, we'll disable the Tx FIFO Empty IRQ. If
there is still some data to receive, we'll adjust the Rx FIFO Threshold
level, so the next IRQ would be raised at the moment of all incoming data
being available in the Rx FIFO.

spi: dw: Add DW SPI controller config structure 
DW APB SSI controller can be used by the two SPI core interfaces:
traditional SPI transfers and SPI memory operations. The controller needs
to be accordingly configured at runtime when the corresponding operations
are executed. In order to do that for the both interfaces from a single
function we introduce a new data wrapper for the transfer mode, data
width, number of data frames (for the automatic data transfer) and the bus
frequency. It will be used by the update_config() method to tune the DW
APB SSI up.

The update_config() method is made exported to be used not only by the DW
SPI core driver, but by the glue layer drivers too. This will be required
in a coming further commit.

spi: dw: Simplify the SPI bus speed config procedure 
The code currently responsible for the SPI communication speed setting up
is a bit messy. Most likely for some historical reason the bus frequency
is saved in the peripheral chip private data. It's pointless now since the
custom communication speed is a SPI-transfer-specific thing and only if
there is no SPI transfer data specified (like during the SPI memory
operations) it can be taken from the SPI device structure. But even in the
later case there is no point in having the clock divider and the SPI bus
frequency saved in the chip data, because the controller can be used for
both SPI-transfer-based and SPI-transfer-less communications. From
software point of view keeping the current clock divider in an SPI-device
specific storage may give a small performance gain (to avoid sometimes a
round-up division), but in comparison to the total SPI transfer time it
just doesn't worth saving a few CPU cycles in comparison to the total SPI
transfer time while having the harder to read code. The only optimization,
which could worth preserving in the code is to avoid unnecessary DW SPI
controller registers update if it's possible. So to speak let's simplify
the SPI communication speed update procedure by removing the clock-related
fields from the peripheral chip data and update the DW SPI clock divider
only if it's really changed. The later change is reached by keeping the
effective SPI bus speed in the internal DW SPI private data.

By doing so we'll finally make the SPI device chip_data serving as it's

spi: dw: Add DWC SSI capability 
Currently DWC SSI core is supported by means of setting up the
core-specific update_cr0() callback. It isn't suitable for multiple
reasons. First of all having exported several methods doing the same thing
but for different chips makes the code harder to maintain. Secondly the
spi-dw-core driver exports the methods, then the spi-dw-mmio driver sets
the private data callback with one of them so to be called by the core
driver again. That makes the code logic too complicated. Thirdly using
callbacks for just updating the CR0 register is problematic, since in case
if the register needed to be updated from different parts of the code,
we'd have to create another callback (for instance the SPI device-specific
parameters don't need to be calculated each time the SPI transfer is
submitted, so it's better to pre-calculate the CR0 data at the SPI-device
setup stage).

So keeping all the above in mind let's discard the update_cr0() callbacks,
define a generic and static dw_spi_update_cr0() method and create the
DW_SPI_CAP_DWC_SSI capability, which when enabled would activate the
alternative CR0 register layout.

While at it add the comments to the code path of the normal DW APB SSI
controller setup to make the dw_spi_update_cr0() method looking coherent.

spi: spi-s3c64xx: swap s3c64xx_spi_set_cs() and s3c64xx_enable_datapath() 
Fix issues with DMA transfers bigger than 512 bytes on Exynos3250. Without
the patches such transfers fail to complete. This solution to the problem
is found in the vendor kernel for ARTIK5 boards based on Exynos3250.

Merge series "spi: spi-mtk-nor: make use of full capability of program mode" from Chuanhong Guo <gch981213@gmail.com>: 
"program" mode on this controller can trigger up to 56 bits of data
shifting. During the operation, data in PRGDATA[0-5] will be
shifted out from MOSI, and data from MISO will be continuously filling
SHREG[0-9].
Currently this mode is used to implement transfer_one_message for 6-byte
full-duplex transfer, but it can execute a transfer for up-to 7 bytes
as long as the last byte is read only.
transfer_one_message is expected to perform full-duplex transfer,
instead of transfer with specific format. mtk_nor_spi_mem_prg is
added here to use this extra byte.

Newer version of this controller can trigger longer data shifting with
shift bytes more than PRGDATA_MAX + SHREG_MAX. This patch is implemented
with that in mind and it checks against both SHREG_MAX and PRG_CNT_MAX
for future support of new controllers.

Patch 3/3 is a fix for:
commit a59b2c7c56 ("spi: spi-mtk-nor: support standard spi properties")
which breaks supports_op logic. But it can't be separated as it depends
on patch 2/3. Fortuantely the broken commit isn't in stable yet.

Chuanhong Guo (3):
  spi: spi-mtk-nor: make use of full capability of prg mode
  spi: spi-mtk-nor: add helper for checking prg mode ops
  spi: spi-mtk-nor: fix op checks in supports_op

spi: atmel: Exposing effective spi speed 
This patch implements the reporting of the effectively used speed_hz for
the transfer by setting xfer->effective_speed_hz.

See the following patch, which adds this feature to the SPI core for more
information:
commit 5d7e2b5ed5 ("spi: core: allow reporting the effectivly used speed_hz for a transfer")

spi: spi-mtk-nor: fix op checks in supports_op 
commit a59b2c7c56 ("spi: spi-mtk-nor: support standard spi properties")
tries to inverse the logic of supports_op when adding
spi_mem_default_supports_op check, but it didn't get it done properly.
There are two regressions introduced by this commit:
1. reading ops supported by program mode is rejected.
2. all ops with special controller routines are incorrectly further
   checked against program mode.

This commits inverses the logic back:
1. check spi_mem_default_supports_op and reject unsupported ops first.
2. return true for ops with special controller routines.
3. check the left ops against controller program mode.

spi: spi-mtk-nor: add helper for checking prg mode ops 
op checking/resizing logic for the newly added mtk_nor_spi_mem_prg is
more complicated. Add two helper functions for them:
mtk_nor_match_prg: check whether an op is supported by prg mode.
mtk_nor_adj_prg_size: adjust data size for mtk_nor_spi_mem_prg.

mtk_nor_match_prg isn't called yet because supports_op is currently
broken. It'll be used in the next fix commit.
