In order to achieve smooth transition of pxa drivers from old legacy dma
handling to new dmaengine, introduce a function to "hide" dma physical
channels from dmaengine.
This is temporary situation where pxa dma will be handled in 2 places :
- arch/arm/plat-pxa/dma.c
- drivers/dma/pxa_dma.c
The resources, ie. dma channels, will be controlled by pxa_dma. The
legacy code will request or release a channel with
pxad_toggle_reserved_channel().
This is not very pretty, but it ensures both legacy and dmaengine
consumers can live in the same kernel until the conversion is done.

Reuse the debugging features which were available in pxa architecture.
This is a copy of the code from arch/arm/plat-pxa/dma, which is doomed
to disappear once the conversion is completed towards dmaengine.
This is a transfer of the commit "[ARM] pxa/dma: add debugfs
entries" (d294948c2ce4e1c85f452154469752cc9b8e876d).

This is a new driver for pxa SoCs, which is also compatible with the former
mmp_pdma.
The rationale behind a new driver (as opposed to incremental patching) was :
- the new driver relies on virt-dma, which obsoletes all the internal
structures of mmp_pdma (sw_desc, hw_desc, ...), and by consequence all the
functions
- mmp_pdma allocates dma coherent descriptors containing not only hardware
descriptors but linked list information
The new driver only puts the dma hardware descriptors (ie. 4 u32) into the
dma pool allocated memory. This changes completely the way descriptors are
handled
- the architecture behind the interrupt/tasklet management was rewritten to be
more conforming to virt-dma
- the buffers alignment is handled differently
The former driver assumed that the DMA channel stopped between each
descriptor. The new one chains descriptors to let the channel running. This
is a necessary guarantee for real-time high bandwidth usecases such as video
capture on "old" architectures such as pxa.
- hot chaining / cold chaining / no chaining
Whenever possible, submitting a descriptor "hot chains" it to a running
channel. There is still no guarantee that the descriptor will be issued, as
the channel might be stopped just before the descriptor is submitted. Yet
this allows to submit several video buffers, and resubmit a buffer while
another is under handling.
As before, dma_async_issue_pending() is the only guarantee to have all the
buffers issued.
When an alignment issue is detected (ie. one address in a descriptor is not
a multiple of 8), if the already running channel is in "aligned mode", the
channel will stop, and restarted in "misaligned mode" to finished the issued
list.
- descriptors reusing
A submitted, issued and completed descriptor can be reused, ie resubmitted if
it was prepared with the proper flag (DMA_PREP_ACK). Only a channel
resources release will in this case release that buffer.
This allows a rolling ring of buffers to be reused, where there are several
thousands of hardware descriptors used (video buffer for example).
Additionally, a set of more casual features is introduced :
- debugging traces
- lockless way to know if a descriptor is terminated or not
The driver was tested on zylonite board (pxa3xx) and mioa701 (pxa27x),
with dmatest, pxa_camera and pxamci.

Current rcar-dmac driver is using spin_lock_irq() / spin_unlock_irq()
in some functions. But, some other driver might call DMAEngine API
during interrupt disabled. In such case, rcar-dmac side spin_unlock_irq()
forcefully allows all interrupts. Therefore, other driver receives
unexpected interruption, and its exclusive access control will be broken.
This patch replaces spin_lock_irq() to spin_lock_irqsave(),
and spin_unlock_irq() to spin_unlock_irqrestore().

The pl330 device could hang infinitely on certain boards when DMA
channels are terminated.
It was caused by lack of runtime resume when executing
pl330_terminate_all() which calls the _stop() function. _stop() accesses
device register and can loop infinitely while checking for device state.
The hang was confirmed by Dinh Nguyen on Altera SOCFPGA Cyclone V
board during boot. It can be also triggered with:
$ echo 1 > /sys/module/dmatest/parameters/iterations
$ echo dma1chan0 > /sys/module/dmatest/parameters/channel
$ echo 1 > /sys/module/dmatest/parameters/run

DMA routers are transparent devices used to mux DMA requests from
peripherals to DMA controllers. They are used when the SoC integrates more
devices with DMA requests then their controller can handle.
DRA7x is one example of such SoC, where the sDMA can hanlde 128 DMA request
lines, but in SoC level it has 205 DMA requests.
The of_dma_router will be registered as of_dma_controller with special
xlate function and additional parameters. The driver for the router is
responsible to craft the dma_spec (in the of_dma_route_allocate callback)
which can be used to requests a DMA channel from the real DMA controller.
This way the router can be transparent for the system while remaining generic
enough to be used in different environments.

There have been major modernization with the standard bus: in ALSA
sequencer core and HD-audio. Also, HD-audio receives the regmap
support replacing the in-house cache register cache code. These
changes shouldn't impact the existing behavior, but rather
refactoring.
In addition, HD-audio got the code split to a core library part and
the "legacy" driver parts. This is a preliminary work for adapting
the upcoming ASoC HD-audio driver, and the whole transition is still
work in progress, likely finished in 4.1.
Along with them, there are many updates in ASoC area as usual, too:
lots of cleanups, Intel code shuffling, etc.
Here are some highlights:
ALSA core:
- PCM: the audio timestamp / wallclock enhancement
- PCM: fixes in DPCM management
- Fixes / cleanups of user-space control element management
- Sequencer: modernization using the standard bus
HD-audio:
- Modernization using the standard bus
- Regmap support
- Use standard runtime PM for codec power saving
- Widget-path based power-saving for IDT, VIA and Realtek codecs
- Reorganized sysfs entries for each codec object
- More Dell headset support
ASoC:
- Move of jack registration to the card level
- Lots of ASoC cleanups, mainly moving things from the CODEC level
to the card level
- Support for DAPM routes specified by both the machine driver and DT
- Continuing improvements to rcar
- pcm512x enhacements
- Intel platforms updates
- rt5670 updates / fixes
- New platforms / devices: some non-DSP Qualcomm platforms, Google's
Storm platform, Maxmim MAX98925 CODECs and the Ingenic JZ4780 SoC

Merge tag 'sound-4.1-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound
Pull sound updates from Takashi Iwai:
"There have been major modernization with the standard bus: in ALSA
sequencer core and HD-audio. Also, HD-audio receives the regmap
support replacing the in-house cache register cache code. These
changes shouldn't impact the existing behavior, but rather
refactoring.
In addition, HD-audio got the code split to a core library part and
the "legacy" driver parts. This is a preliminary work for adapting
the upcoming ASoC HD-audio driver, and the whole transition is still
work in progress, likely finished in 4.1.
Along with them, there are many updates in ASoC area as usual, too:
lots of cleanups, Intel code shuffling, etc.
Here are some highlights:
ALSA core:
- PCM: the audio timestamp / wallclock enhancement
- PCM: fixes in DPCM management
- Fixes / cleanups of user-space control element management
- Sequencer: modernization using the standard bus
HD-audio:
- Modernization using the standard bus
- Regmap support
- Use standard runtime PM for codec power saving
- Widget-path based power-saving for IDT, VIA and Realtek codecs
- Reorganized sysfs entries for each codec object
- More Dell headset support
ASoC:
- Move of jack registration to the card level
- Lots of ASoC cleanups, mainly moving things from the CODEC level to
the card level
- Support for DAPM routes specified by both the machine driver and DT
- Continuing improvements to rcar
- pcm512x enhacements
- Intel platforms updates
- rt5670 updates / fixes
- New platforms / devices: some non-DSP Qualcomm platforms, Google's
Storm platform, Maxmim MAX98925 CODECs and the Ingenic JZ4780 SoC
Misc:
- ice1724: Improved ESI W192M support
- emu10k1: Emu 1010 fixes/enhancement"

Here's the big staging driver patchset for 4.1-rc1.
There's a lot of patches here, the Outreachy application period happened
during this development cycle, so that means that there was a lot of
cleanup patches accepted. Other than the normal coding style and sparse
fixes here, there are some driver updates and work toward making some of
the drivers into "mergable" shape (like the Unisys drivers.)
All of these have been in linux-next for a while.

Only one framework update this time around, a change from Lars-Peter to
move full to pm_ops and remove the legacy bus PM ops. Otherwise it's
all driver updates:
- Make the spidev driver complain loudly if registered as spidev with
DT rather than with a compatible string, hopefully helping people
avoid making that mistake.
- Error handling and robustness fixes for the Designware and Intel MID
drivers from Andy Shevchenko.
- Substantial performance improvements for the Raspberry Pi driver from
Martin Sperl.
- Several new features for spidev_test from Adrian Remonda and Ian
Abbott.
