Pull MMC update from Chris Ball:
"MMC highlights for 3.10:
Core:
- Introduce MMC_CAP2_NO_PRESCAN_POWERUP to allow skipping
mmc_power_up() at boot/initialization time if it's already
happened, for performance (faster boot time) reasons.
- Fix a bit width test failure that resulted in old eMMC cards being
put into 1-bit mode when 4-bit mode was available.
- Expose fwrev/hwrev for MMCv4 parts.
- Improve card removal logic in the case where the card's removed
slowly; we were missing card removal events if the card retained
contact with the slot pads for long enough to reply to a CMD13
while being removed.
Drivers:
- davinci_mmc: Support using PIO instead of DMA.
- dw_mmc: Add support for Exynos4412.
- mxcmmc: DT support, use slot-gpio API.
- mxs-mmc: Add broken-cd/cd-inverted/non-removable DT property
support.
- sdhci-sirf: New sdhci-pltfm driver for CSR SiRF SoCs:
SiRFprimaII: unicore ARM Cortex-A9
SiRFatlas6: unicore ARM Cortex-A9
SiRFmarco: dual core ARM Cortex-A9 SMP
- sdhci-tegra: Add support for Tegra114 platforms, use
mmc_of_parse()"

Pull ARM SoC board specific changes (part 1) from Olof Johansson:
"These changes are all for board specific files. These used to make up
a large portion of the ARM changes in the past, but as we are
generalizing the support and moving to device tree probing, this has
gotten significantly smaller.
The only platform actually adding new code here at the moment is
Renesas shmobile, as they are still busy converting their code to
device tree and have not come far enough to not need it."

Some Exynos-based boards contain secure firmware and must use firmware
operations to set up some hardware.
This patch adds firmware operations for Exynos secure firmware and a way
for board code and device tree to specify that they must be used.
Example of use:
In board code:
...MACHINE_START(...)
/* ... */
.init_early = exynos_firmware_init,
/* ... */
MACHINE_END
In device tree:
/ {
/* ... */
firmware@0203F000 {
compatible = "samsung,secure-firmware";
reg = <0x0203F000 0x1000>;
};
/* ... */

git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc
Pull ARM SoC driver changes from Olof Johansson:
"This is a rather large set of patches for device drivers that for one
reason or another the subsystem maintainer preferred to get merged
through the arm-soc tree. There are both new drivers as well as
existing drivers that are getting converted from platform-specific
code into standalone drivers using the appropriate subsystem specific
interfaces.
In particular, we can now have pinctrl, clk, clksource and irqchip
drivers in one file per driver, without the need to call into platform
specific interface, or to get called from platform specific code, as
long as all information about the hardware is provided through a
device tree.
Most of the drivers we touch this time are for clocksource. Since now
most of them are part of drivers/clocksource, I expect that we won't
have to touch these again from arm-soc and can let the clocksource
maintainers take care of these in the future.
Another larger part of this series is specific to the exynos platform,
which is seeing some significant effort in upstreaming and
modernization of its device drivers this time around, which
unfortunately is also the cause for the churn and a lot of the merge
conflicts.
There is one new subsystem that gets merged as part of this series:
the reset controller interface, which is a very simple interface for
taking devices on the SoC out of reset or back into reset. Patches to
use this interface on i.MX follow later in this merge window, and we
are going to have other platforms (at least tegra and sirf) get
converted in 3.11. This will let us get rid of platform specific
callbacks in a number of platform independent device drivers."

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.

From Stephen Warren <swarren@wwwdotorg.org>:
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.

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.

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.

Adds a function to read the various GPMC chip-select settings from
device-tree and store them in the gpmc_settings structure.
Update the GPMC device-tree binding documentation to describe these
options.
