Pull ARM SoC fixes from Olof Johansson:
"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 and there.
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"

2) add new style clock method in driver

In EXYNOS5 series SoCs, PMU has registers to enable/disable mask/unmask
watchdog timer which is not the case with s3c series SoCs so, there is a
need to have different compatible names for watchdog to handle these pmu
registers access.
Hence this patch removes watchdog node from Exynos5.dtsi common file and
make it separate by updating existing node in Exynos5250 and adding new node
to Exynos5420. This patch also makes the watchdog node enabled by default

Move the kirkwood DT support into mach-mvebu, and make them part of
ARCH_MULTI_V5. Minimal changes have been made in order to make it
boot. Cleanup of the header files and integration with mvebu will
take place in following patches.
In order to help Debian transition between mach-kirkwood and
mach-mvebu, the DTS files are compiled for both, allowing Debian to
continue using mach-kirkwood until all remaining boards are supported
by mach-mvebu. Debian is then expected to simply swap from
mach-kirkwood to mach-mvebu and mach-kirkwood will be removed.

Add device tree fragments and files to support many of the kirkwood
based Synology NAS devices. This is a modification of
Andrew Lunn's <andrew@lunn.ch> translation of the board setup file
maintained by Ben Peddell <klightspeed@killerwolves.net>
The Ricoh RS5C372 RTC was used in all 2009 units and some 2010 units.
All other Synology Kirkwood-based DiskStations and RackStations use
the Seiko S35390A RTC.
Most of the 1-bay and 2-bay units use the GPIOs that are multiplexed
with the built-in SATA interface activity/presence pins on mpp 20-23,
while the 4-bay units use ge01 and a PCIe SATA controller, and put the
software controlled HDD leds on mpp 36-43.
Most of the 6281 units with HDD power controls use mpp 29 and 31, while
most of the 6282 units with HDD power controls use mpp 30, 34, 44 and 45
and provide a model ID on mpp 28, 29, 46 and 47. Pre-2012 units and
most 4-bay units didn't have a separate power control for HDD1. These
power controls are presumably to limit startup current from the 12V
brick power supply.
Instead of using separate dtsi files in a synology directory, this
patch uses a single dtsi file containing all of the modules for
these boards, with all of the modules not common to all boards
disabled. The board dts files then enable the appropriate modules for
their boards.

Pull devicetree fixes from Grant Likely:
"Device tree compatible match order bug fix
This branch contains a bug fix for the way devicetree code identifies
the type of device. Device drivers can contain a list of
of_device_ids, but it more than one entry will match, then the device
driver may choose the wrong one. Commit 105353145e, "match each node
compatible against all given matches first", was queued for v3.14 but
ended up causing other bugs. Commit 06b29e76a7 attempted to fix it
but it had other bugs. Merely reverting the fix and waiting until
v3.15 isn't a good option because there is code in v3.14 that depends
on the revised behaviour to boot.
This branch should finally fixes the problem correctly. This time
instead of just hoping that the patch is correct, this branch also
adds new testcases that validate the behaviour.
The changes in this branch are larger than I would like for a -rc

Unlike other build products in the Linux kernel, there is no 'make
*install' mechanism to put devicetree blobs in a standard place.
This commit adds a new 'dtbs_install' make target which copies all of
the dtbs into the INSTALL_DTBS_PATH directory. INSTALL_DTBS_PATH can be
set before calling make to change the default install directory. If not
set then it defaults to:
$INSTALL_PATH/dtbs/$KERNELRELEASE.
This is done to keep dtbs from different kernel versions separate until
things have settled down. Once the dtbs are stable, and not so strongly
linked to the kernel version, the devicetree files will most likely move
to their own repo. Users will need to upgrade install scripts at that
time.
v7: (reworked by Grant Likely)
- Moved rules from arch/arm/Makefile to arch/arm/boot/dts/Makefile so
that each dtb install could have a separate target and be reported as
part of the make output.
- Fixed dependency problem to ensure $KERNELRELEASE is calculated before
attempting to install
- Removed option to call external script. Copying the files should be
sufficient and a build system can post-process the install directory.
Despite the fact an external script is used for installing the kernel,
I don't think that is a pattern that should be encouraged. I would
rather see buildroot type tools post process the install directory to
rename or move dtb files after installing to a staging directory.
- Plus it is easy to add a hook after the fact without blocking the
rest of this feature.
- Move the helper targets into scripts/Makefile.lib with the rest of the
common dtb rules

The testcase data is usable by any platform. This patch moves it into
the drivers/of directory so it can be included by any architecture.
Using the test cases requires manually adding #include <testcases.dtsi>

pretty though. A useful project would be to make the testcase code

On imx6sl-evk board the VGEN1 regulator powers up the NVCC_1P2V domain of the
imx6sl SoC, so we need to keep it always powered.
According to imx6sl datasheet the GPIO block has three supplies:
NVCC33_IO, NVCC18_IO and NVCC_1P2V and it states that:
"All digital I/O supplies (NVCC_xxxx) must be powered under normal conditions
whether the associated I/O pins are in use or not"
This problem has been observed by the fact that a GPIO connected to an LED could
not work when the PMIC driver was enabled.
Keeping VGEN1 regulator always enabled fixes the problem.
