241a987126 Merge branch 'exynos/pwm-clocksource' into late/multiplatform
This series from Tomasz Figa restores support for the pwm clocksource
in Exynos, which was broken during the conversion of the platform
to the common clk framework. The clocksource is only used in one
board in the mainline kernel (universal_c210), and this makes it
work for DT based probing as well as restoring the non-DT based
case.

* exynos/pwm-clocksource:
  ARM: dts: exynops4210: really add universal_c210 dts
  ARM: dts: exynos4210: Add basic dts file for universal_c210 board
  ARM: dts: exynos4: Add node for PWM device
  ARM: SAMSUNG: Do not register legacy timer interrupts on Exynos
  clocksource: samsung_pwm_timer: Work around rounding errors in clockevents core
  clocksource: samsung_pwm_timer: Correct programming of clock events
  clocksource: samsung_pwm_timer: Use proper clockevents max_delta
  clocksource: samsung_pwm_timer: Add support for non-DT platforms
  clocksource: samsung_pwm_timer: Drop unused samsung_pwm struct
  clocksource: samsung_pwm_timer: Keep all driver data in a structure
  clocksource: samsung_pwm_timer: Make PWM spinlock global
  clocksource: samsung_pwm_timer: Let platforms select the driver

c4c54da24b Merge branch 'reset/for_v3.10' of git://git.pengutronix.de/git/pza/linux into next/drivers
From Philipp Zabel, this is a series that adds a simple API for devices
to request being reset by a separate reset controller hardware, and
it implements reset signal device tree bindings.

4e11f848c6 dt: describe base reset signal binding
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.

2b07910131 ARM: tegra: clock driver development
This branch contains most fixes and enhancements to the Tegra common
 clock driver. The main new feature is a driver for Tegra114, which
 coupled with later device tree changes enables many devices on that
 chip, such as MMC, I2C, etc.
 
 This branch depends on a patch in:
 
 git://git.linaro.org/people/mturquette/linux.git clk-for-3.10
 
 Mike has stated that this branch is stable, and is aware of this
 dependency and merge.
 
 Mike's branch is based on v3.9-rc3, which includes a USB change which
 causes problems on Tegra. That problem was fixed in v3.9-rc4. Hence,
 this branch pulls in v3.9-rc4 to ensure bisectability as much as
 possible.
 
 This branch is based on v3.9-rc4, followed by a merge of previous Tegra
 "soc" pull request, followed by a merge of clk-for-3.10.

32cde0b514 ARM: OMAP2+: Convert ONENAND to retrieve GPMC settings from DT
When booting with device-tree, retrieve GPMC settings for ONENAND from
the device-tree blob. This will allow us to remove all static settings
stored in the gpmc-nand.c in the future once the migration to
device-tree is complete.

The user must now specify the ONENAND device width in the device-tree
binding so that the GPMC can be programmed correctly. Therefore, update
the device-tree binding documentation for ONENAND devices connected to
the GPMC to reflect this.

Please note that this does not include GPMC timings for ONENAND. The
timings are being calculated at runtime.

There is some legacy code that only enables read wait monitoring for
non-OMAP3 devices. There are no known OMAP3 device issues that prevent
this feature being enabled and so when booting with device-tree use the
wait-monitoring settings described in the device-tree blob.

d36b4cd46d ARM: OMAP2+: Add additional GPMC timing parameters
Some of the GPMC timings parameters are currently missing from the GPMC
device-tree binding. Add these parameters to the binding documentation
as well as code to read them. Also add either "-ps" or "-ns" suffix to
the GPMC timing properties to indicate whether the timing is in
picoseconds or nanoseconds.

The existing code in gpmc_read_timings_dt() is checking the value of
of_property_read_u32() and only is successful storing the value read
in the gpmc_timings structure. Checking the return value in this case
is not necessary and we can simply read the value, if present, and
store directly in the gpmc_timings structure. Therefore, simplify the
code by removing these checks.

The comment in the gpmc_read_timings_dt() function, "only for OMAP3430"
is also incorrect as it is applicable to all OMAP3+ devices. So correct
this too.

e3276998da clk: sunxi: rename compatible strings
During the introduction of the Allwinner SoC platforms, sunxi was
initially meant as a generic name for all the variants of the Allwinner
SoC.

It was ok at the time of the support of only the A10 and A13 that
look pretty much the same; but it's beginning to be troublesome with
the future addition of the Allwinner A31 (sun6i) that is quite
different, and would introduce some weird logic, where sunxi would
actually mean in some case sun4i and sun5i but without sun6i...

Moreover, it makes the compatible strings naming scheme not consistent
with other architectures, where usually for this kind of compability, we
just use the oldest SoC name that has this IP, so let's do just this.

d52701d39e mfd: ab8500: Kill "reg" property from binding
The ab8500 device is a child of the prcmu device, which is a memory mapped
bus device, whose children are addressable using physical memory addresses,
not using mailboxes, so a mailbox number in the ab8500 node cannot be
parsed by DT. Nothing uses this number, since it was only introduced
as part of the failed attempt to clean up prcmu mailbox handling, and
we can simply remove it.
