Here's the big drivers/staging/ update for 3.14-rc1
Lots and lots of cleanups, IIO driver updates are also mixed in here due
to the subsystem still crossing staging and drivers/iio/, and the dwc2
driver is moved out of staging. There's a new driver (rts5208), which
ends up making us adding more lines than removing, but overall there was
lots of work toward moving code out of here, which was good.

Here's the big driver core and sysfs patch set for 3.14-rc1.
There's a lot of work here moving sysfs logic out into a "kernfs" to
allow other subsystems to also have a virtual filesystem with the same
attributes of sysfs (handle device disconnect, dynamic creation /
removal as needed / unneeded, etc. This is primarily being done for
the cgroups filesystem, but the goal is to also move debugfs to it when
it is ready, solving all of the known issues in that filesystem as well.
The code isn't completed yet, but all should be stable now (there is a
big section that was reverted due to problems found when testing.)
There's also some other smaller fixes, and a driver core addition that
allows for a "collection" of objects, that the DRM people will be using
soon (it's in this tree to make merges after -rc1 easier.)
All of this has been in linux-next with no reported issues.

The MOXA ART SoC has a DMA controller capable of offloading expensive
memory operations, such as large copies. This patch adds support for
the controller including four channels. Two of these are used to
handle MMC copy on the UC-7112-LX hardware. The remaining two can be
used in a future audio driver or client application.

The Allwinner A20 has an ethernet controller that seems to be
an early version of Synopsys DesignWare MAC 10/100/1000 Universal,
which is supported by the stmmac driver.
Allwinner's GMAC requires setting additional registers in the SoC's
clock control unit.
The exact version of the DWMAC IP that Allwinner uses is unknown,
thus the exact feature set is unknown.

The snps,phy-addr device tree property is non-standard, and should be
removed in favor of proper phy node support. Remove it from the binding
documents and warn if the property is still used.
Most PHYs respond to address 0, but a few don't, so auto-detect PHY
address by default, to make up for the lack of explicit address selection.

The current .init and .exit callbacks requires access to driver
private data structures. This is not a good seperation and abstraction.
Instead, we add a new .setup callback for allocating private data, and
pass the returned pointer to the other callbacks.

Though described as required, the "phy-handle" property for the DaVinci EMAC
binding is actually optional, as the driver will happily function without it,
assuming 100/FULL link; the property is not specified either in the example
device node, or in the actual EMAC device nodes for DA850 and AM3517 device
trees.

This makes all of a machine's memory accessible to remote debugging via
FireWire, using the physical response unit (i.e. RDMA) of OHCI-1394 link
layer controllers.
This requires actual support by the controller. The only ones currently
known to support it are Agere/LSI FW643. Most if not all other OHCI-1394
controllers do not implement the optional Physical Upper Bound register.
With them, RDMA will continue to be limited to the lowermost 4 GB.
firewire-ohci's startup message in the kernel log is augmented to tell
whether the controller does expose more than 4 GB to RDMA.
While OHCI-1394 allows for a maximum Physical Upper Bound of
0xffff'0000'0000 (near 256 TB), this implementation sets it to
0x8000'0000'0000 (128 TB) in order to avoid interference with applications
that require interrupt-served asynchronous request reception at
respectively low addresses.
Note, this change does not switch remote DMA on. It only increases the
range of remote access to all memory (instead of just 4 GB) whenever
remote DMA was switched on by other means. The latter is achieved by
setting firewire-ohci's remote_dma parameter, or if the physical DMA
filter is opened through firewire-sbp2.
Derived from patch "firewire: Enable physical DMA above 4GB" by
Peter Hurley <peter@hurleysoftware.com> from March 27, 2013.

Some OMAP clocks require knowledge about their parent clockdomain for
book keeping purposes. This patch creates a new DT binding for TI
clockdomains, which act as a collection of device clocks. Clockdomain
itself is rather misleading name for the hardware functionality, as at
least on OMAP4 / OMAP5 / DRA7 the clockdomains can be collections of either
clocks and/or IP blocks, thus idle-domain or such might be more appropriate.
For most cases on these SoCs, the kernel doesn't even need the information
and the mappings can be ignored.

This patch adds support for TI specific gate clocks. These behave as basic
gate-clock, but have different ops / hw-ops for controlling the actual
gate, for example waiting until the clock is ready. Several sub-types
are supported:
- ti,gate-clock: basic gate clock with default ops/hwops
- ti,clkdm-gate-clock: clockdomain level gate control
- ti,dss-gate-clock: gate clock with DSS specific hardware handling
- ti,am35xx-gate-clock: gate clock with AM35xx specific hardware handling
- ti,hsdiv-gate-clock: gate clock with OMAP36xx hardware errata handling

This adds interrupt functionality for i2c chips to the driver.
They can act as a interrupt-controller and generate interrupts, if
the inputs change.
This is tested with a mcp23017 chip on an arm based platform.
v3:
- be a bit more clear that the irq functionality is also available
on spi versions of the chips, but the linux driver does not support
this yet
v2:
- some more word about irq-mirror property in binding doc
- use of_read_bool instead of of_find_property for
"interrupt-contrller" and "irq-mirror"
- cache the "interrupt-controller" for remove function
- do set the irq-mirror bit only if device is marked as
interrupt-controller
- do create the irq mapping and setup of irq_desc of all possible
interrupts in probe path instead of in gpio_to_irq
- mark gpios as in use as interrupts in irq in irq_startup and
unlock it in irq_shutdown
- rename virq to child_irq
- remove dev argument from mcp23s08_irq_setup function
- move gpiochip_add before mcp23s08_irq_setup in probe path
