Pull ARM SoC driver changes from Olof Johansson:
"SoC-near driver changes that we're merging through our tree. Mostly
because they depend on other changes we have staged, but in some cases
because the driver maintainers preferred that we did it this way.
This contains a largeish cleanup series of the omap_l3_noc bus driver,
cpuidle rework for Exynos, some reset driver conversions and a long
branch of TI EDMA fixes and cleanups, with more to come next release.
The TI EDMA cleanups is a shared branch with the dmaengine tree, with
a handful of Davinci-specific fixes on top.
After discussion at last year's KS (and some more on the mailing
lists), we are here adding a drivers/soc directory. The purpose of
this is to keep per-vendor shared code that's needed by different
drivers but that doesn't fit into the MFD (nor drivers/platform)
model. We expect to keep merging contents for this hierarchy through
arm-soc so we can keep an eye on what the vendors keep adding here and
not making it a free-for-all to shove in crazy stuff"

reset drivers.

Pull ARM SoC device tree changes from Arnd Bergmann:
"A large part of the arm-soc patches are nowadays DT changes, adding
support for new SoCs, boards and devices without changing kernel
source. The plan is still to move the devicetree files out of the
kernel tree and reduce the amount of churn going on here, but we keep
finding reasons to delay doing that.
Changes are really all over the place, with little sticking out
particularly. We have contributions from a total of 116 people in
this branch.
Unfortunately, the size of this branch also causes a significant
number of conflicts at the moment, typically when subsystem
maintainers merge patches that change the driver at the same time as
the dts files. In most cases this could be avoided because the dts
changes are supposed to be compatible in both ways, and we are asking
everyone to send ARM dts changes through our tree only"

The SRC has auto-deasserting reset bits that control reset lines to
the GPU, VPU, IPU, and OpenVG IP modules. This patch adds a reset
controller that can be controlled by those devices using the
reset controller API.

This binding is intended to represent the hardware reset signals present
internally in most IC (SoC, FPGA, ...) designs.
It consists of a binding for a reset controller device (provider), and a
pair of properties, "resets" and "reset-names", to link a device node
(consumer) to its reset controller via phandle, similarly to the clock
and interrupt bindings.
The reset controller has all information necessary to reset the consumer
device. That could be provided via device tree, or it could be implemented
in hardware.
The aim is to enable device drivers to request a framework API to issue a
reset simply by providing their struct device pointer as the most common
case.
