Add clock event support for CMT1 timer channel 0
to the r8a73a4 SoC code. The CMT is used together
with a 32KHz clock in this case.

Add clock event support for CMT0 timer channel 0
to the r8a7790 SoC code. On most ARM mach-shmobile
the CMT is hooked up to a 32KHz clock but on r8a7790
a 31.7KHz clock is instead used.

The r8a7790 MSTP bits should be kept sorted in the same way
as on other mach-shmobile SoCs. Move the HSCIF and thermal
bits to clean up the current state.

r8a73a4 SoCs have numerous I2C controllers, of which 9 are compatible with
the i2c-sh_mobile.c driver. This patch adds clock definitions for them.

The Z2 clock on r8a73a4 is used to clock the 4 Cortex A7 cores on the SoC.
Add a definition for this clock to later use it from the arm_big_little
CPUFreq driver.

clk_set_rate() should only be called with exact rates, returned by
clk_round_rate(). However, it is still good to verify, that the value,
passed to clock's .set_rate() method is at least valid. This patch adds
such a check for the Z-clock on r8a73a4.

This patch adds support for the Z-clock on r8a73a4 SoCs, which is driving
the Cortex A15 core, and a "cpufreq-cpu0" platform device. Adding an
"operating-points" property to the CPU0 DT node and a regulator, this
patch allows platforms to use the generic cpufreq-cpu0 driver to use
SoC's DVFS capabilities.

To reconfigure clocks, controlled by FRQCRA and FRQCRB, a kick bit has to
be set and to make sure the setting has taken effect, it has to be read
back repeatedly until it is cleared by the hardware. This patch adds the
waiting part, that was missing until now.

Pull ARM SoC DT updates from Olof Johansson:
"Device tree and bindings updates for 3.12.
General additions of various on-chip and on-board peripherals on
various platforms as support gets added. Some of the bigger changes
are:
- Addition of (new) PCI-e support on Tegra.
- More Tegra4 support, including PMC configuration for Dalmore.
- Addition of a new board for Exynos4 (trats2) and more bindings for
4x12 IP.
- Addition of Allwinner A20 and A31 SoC and board files.
- Move of the ST Ericsson device tree files to now use ste-* prefix.
- More move of hardware description of shmobile platforms to DT.
- Two new board dts files for Freescale MXs"

Update the EMEV2 struct map_desc to exclude the SMU
and also include the ->map_io() callback in the DT
version of EMEV2 board support.
The EMEV2 SMP code can these days perform ioremap()
early on without the SMU information in the io_desc[].
To correctly support SMP in case of DT-only board
support then the ->map_io() callback is needed.

Pull ARM SoC cleanups from Olof Johansson:
"This branch contains code cleanups, moves and removals for 3.12.
There's a large number of various cleanups, and a nice net removal of
13500 lines of code.
Highlights worth mentioning are:
- A series of patches from Stephen Boyd removing the ARM local timer
API.
- Move of Qualcomm MSM IOMMU code to drivers/iommu.
- Samsung PWM driver cleanups from Tomasz Figa, removing legacy PWM
driver and switching over to the drivers/pwm one.
- Removal of some unusued auto-generated headers for OMAP2+ (PRM/CM).
There's also a move of a header file out of include/linux/i2c/ to
platform_data, where it really belongs. It touches mostly ARM
platform code for include changes so we took it through our tree"

This patch removes r8a7778_init_irq(), since no-one is using it.
And now, there is no reason to have r8a7778_init_irq_common().
r8a7778_init_irq_dt() includes it.
