This commit adds a bare bones driver support for TLV320AIC31XX family
audio codecs. The driver adds basic stereo playback trough headphone
and speaker outputs and mono capture trough microphone inputs.
The driver is currently missing support at least for mini DSP features
and jack detection. I have tested the driver only on TLV320AIC3111,
but based on the data sheets TLV320AIC3100, TLV320AIC3110, and
TLV320AIC3120 should work Ok too.
The base for the implementation was taken from:
git@gitorious.org:ti-codecs/ti-codecs.git ajitk/topics/k3.10.1-aic31xx
-branch at commit 77504eba0294764e9e63b4a0c696b44db187cd13.

This patch provides bindings for the 64-bit timer in the KeyStone
architecture devices. The timer can be configured as a general-purpose 64-bit
timer, dual general-purpose 32-bit timers. When configured as dual 32-bit
timers, each half can operate in conjunction (chain mode) or independently
(unchained mode) of each other.
It is global timer is a free running up-counter and can generate interrupt
when the counter reaches preset counter values.

A collection of fixes for ARM platforms. A little large due to us missing to
do one last week, but there's nothing in particular here that is in itself
large and scary.
Mostly a handful of smaller fixes all over the place. The majority is made
up of fixes for OMAP, but there are a few for others as well. In particular,
there was a decision to rename a binding for the Broadcom pinctrl block that
we need to go in before the final release since we then treat it as ABI.

This set of changes reorganises imx-drm's DT bindings by re-using the OF
graph parsing code which was located in drivers/media, removing the
temporary bindings.
The result is that more TODO entries are now removed. While we're not
quite done with this yet as there's a few straggling updates to imx-ldb
to come, but leaving these out is not detrimental at this point in time
- they are more an enhancement.
However, this pull has the additional complication that we're sharing
seven commits with Mauro's V4L git tree, which move the OF graph parsing
code out of drivers/media into drivers/of. Philipp's imx-drm changes
depend on these and my previously committed round of imx-drm commits.
Hence, the diffstat below is from a test merge with your tree head
(17b02809cf).
Mauro merged those seven commits earlier today as a git pull, so both
trees will be sharing exactly the same commit IDs.
I've given these changes a spin here on both my Hummingboard and Cubox-i4
(one is iMX6Solo, the other is iMX6Quad based), which includes Xorg using
the DRM device directly, and I find nothing wrong.
The diffstat does look a little scarey - this is because we're having to
update the ARM DT files along with this change, and obviously the
dependency on the OF graph parsing code.

on i.MX6.

This reverts commit 40b367d95f.
Russell King has raised the idea of creating a proper PMU driver for
this SoC that would incorporate the functionality currently in this
driver. It would also cover the use case for the graphics subsystem on
this SoC.
To prevent having to maintain the devicetree ABI for this limited
interrupt-handler driver, we revert the driver before it hits a mainline

regressions. There is a single framework fix that prevents dereferencing
a NULL pointer when calling clk_get. The range of fixes for clock driver
regressions spans memory leak fixes, touching the wrong registers that
cause things to explode, misconfigured clock rates that result in
non-responsive devices and even some boot failures. The most benign fix
is DT binding doc typo. It is a stable ABI exposed from the kernel that
was introduced in -rc1, so best to fix it now.

The Xilinx XADC is a ADC that can be found in the series 7 FPGAs from Xilinx.
The XADC has a DRP interface for communication. Currently two different
frontends for the DRP interface exist. One that is only available on the ZYNQ
family as a hardmacro in the SoC portion of the ZYNQ. The other one is available
on all series 7 platforms and is a softmacro with a AXI interface. This binding
document describes the bindings for both of them since the bindings are very
similar.
Each of them needs:
* A address range where the registers are mapped
* An interrupt number for the device interrupt
* A clock. For the the ZYNQ hardmacro interface this is the modules PCAP
clock, for the AXI softmacro it is the AXI bus interface clock.
Additionally the bindings specify whether an external multiplexer is used and in
which mode it is used. The devicetree bindings also describe which external
channels are connected and in which configuration.

Add bindings for TI Async External Memory Interface (AEMIF) controller.
The Async External Memory Interface (EMIF16/AEMIF) controller is intended to
provide a glue-less interface to a variety of asynchronous memory devices like
ASRA M, NOR and NAND memory. A total of 256M bytes of any of these memories
can be accessed via 4 chip selects with 64M byte access per chip select.
We are not encoding CS number in reg property, it's memory partition number.
The CS number is encoded for Davinci NAND node using standalone property
"ti,davinci-chipselect" and we need to provide two memory ranges to it,
as result we can't encode CS number in "reg" for AEMIF child devices
(NAND/NOR/etc), as it will break bindings compatibility.
In this patch, NAND node is used just as an example of child node.

Some SoCs need parts of their sram for special purposes. So while being part
of the peripheral, it should not be part of the genpool controlling the sram.
Therefore add the option to define reserved regions as subnodes of the
sram-node similar to defining reserved global memory regions.

Add support for the MSIOF variant in the R-Car H2 (r8a7790) and M2
(r8a7791) SoCs.
Binding documentation:
- Add future-proof "renesas,msiof-<soctype>" compatible values,
- The default for "renesas,rx-fifo-size" is 256 on R-Car H2 and M2,
- "renesas,tx-fifo-size" and "renesas,rx-fifo-size" are deprecated for
soctype-specific bindings,
- Add example bindings.
Implementation:
- MSIOF on R-Car H2 and M2 requires the transmission of dummy data if
data is being received only (cfr. "Set SICTR.TSCKE to 1" and "Write
dummy transmission data to SITFDR" in paragraph "Transmit and Receive
Procedures" of the Hardware User's Manual).
- As RX depends on TX, MSIOF on R-Car H2 and M2 also lacks the RSCR
register (Receive Clock Select Register), and some bits in the RMDR1
(Receive Mode Register 1) and TMDR2 (Transmit Mode Register 2)
registers.
- Use the recently introduced SPI_MASTER_MUST_TX flag to enable support
for dummy transmission in the SPI core, and to differentiate from other
MSIOF implementations in code paths that need this.
- New DT compatible values ("renesas,msiof-r8a7790" and
"renesas,msiof-r8a7791") are added, as well as new platform device
names ("spi_r8a7790_msiof" and "spi_r8a7791_msiof").
- The default RX FIFO size is 256 words on R-Car H2 and M2.
This is loosely based on a set of patches from Takashi Yoshii
<takasi-y@ops.dti.ne.jp>.

A collection of fixes for ARM platforms. Most are fixes for DTS files,
mostly from DT conversion on OMAP which is still finding a few issues here

There's a couple of small stale code removal patches that we usually
queue for the next release instead, but they seemed harmless enough to
bring in now.
Also, a fix for backlight on some PXA platforms, and a cache configuration
fix for Tegra, etc.

There are a few fixes in here that might, earlier in a cycle, have gone
to Greg as fixes. Given they are either minor or have never actually
been observed as causing trouble (the locking bug in the event code) and
are invasive, I have included them in this pull request, targeting the
3.15 merge window instead.
The rest are pretty uncontroversial new drivers, a handy little tool for
the example code in our documentation and little cleanups.
New drivers
* Freescale Vybrid and i.MX6SLX ADC driver.
* HID Sensor hub proximity sensors.
* HID Sensor hub pressure sensors.
* LPS25H Pressure sensors added to the ST micro pressure sensor driver.
New functionality
* lsiio tool. This is added to the staging tree as we haven't yet moved
the example code it sits with out. Moving this code out is now a reasonably
high priority but holding up this tool in the meantime did not seem
worthwhile.
* mag3110 - add missing scale factor for temperature output to userspace.
Cleanups
* Fix a bug in the event reporting in which a spin lock might be held over
when a sleep occured. A similar bug was found by Lars in the buffer code.
It has not to our knowledge been observed as actually occuring and is
a little too invasive to push out as a fix.
* Drop the IIO_ST macro after clearing out all users. This macro was a very
bad idea leading to a number of bugs after it stopped covering all elements
of the structure being assigned and people started making assumptions about
what it did cover. Glad to see it go!
* Avoid applying extended name to shared attributes as it makes no sense.
No in tree drivers were using the combination, hence not pushed out as
a fix.
* ad799x - move to devm_request_threaded_irq to reduce boilerplate clean up.
* bma180 - make the low_pass_filter_3db_frequency info element shared rather
than per attribute. The old approach was valid but not as clean as it might
be and was setting a bad example. Hence the cleanup.
* mxs-lradc - propogate the error code form a platform_get_irq call rather than
eating it up by returning -EINVAL on all errors.
* ad799x - typo fix in the copyright message. Either that or Michael was
asserting a copyright that moved backwards in time by about a thousand years.
* ad799x - use a regulator for vref rather than platform data. The driver
dates from just as the regulator framework was coming into common use so
provides an alternative way of specifying the reference voltage. We no
longer need that approach so drop it in favour of a regulator only approach.
* max1363 - some internal vref values were out by a small amount. The effect
would have been tiny and no one noticed hence not pushing this through as
a fix.
* core - replace some pointless goto error_ret (with no clean up) lines with
direct returns. This is my bad coding style so I'm glad to see it cleaned
up.
* core - avoid a kasprintf that just directly prints a string with no
formatting elements. This has always been there but Lars just noticed it.

The older Allwinner SoCs (A10, A13, A10s and A20) all have the same SPI
controller.
Unfortunately, this SPI controller, even though quite similar, is significantly
different from the recently supported A31 SPI controller (different registers
offset, split/merged registers, etc.). Supporting both controllers in a single
driver would be unreasonable, hence the addition of a new driver.
Like its more recent counterpart, it supports DMA, but the driver only does PIO
until we have a dmaengine driver for this platform.

This avoids the ugliness of creating a nested platform device from probe.
While moving it around anyways, move the mk6q phy init code from probe
to imx_sata_enable, as the phy needs to be re-initialized on resume too,
otherwise the drive won't be recognized after resume.
Tested on a wandboard i.mx6 quad.

This patch adds support for the ahci sata controler found on Allwinner A10
and A20 SoCs to the ahci_platform driver.
Orignally written by Olliver Schinagl using the approach of having a platform
device which probe method creates a new child platform device which gets
driven by ahci_platform.c, as done by ahci_imx.c .
Refactored by Hans de Goede to add most of the non sunxi specific functionality
to ahci_platform.c and use a platform_data pointer from of_device_id for the
sunxi specific bits.

The new Armada 375 and Armada 38x Marvell SoCs are based on Cortex-A9
CPU cores and use the ARM GIC as their main interrupt controller.
However, for various purposes (wake-up from suspend, MSI interrupts),
they have kept a separate MPIC interrupt controller, acting as a slave
to the GIC. This MPIC was already used as the primary controller on
previous Marvell SoCs, so this commit extends the existing driver to
allow the MPIC to be used as a GIC slave.
