The msm timer binding I wrote is bad. First off, the clock
frequency in the binding for the dgt is wrong. Software divides
down the input rate by 4 to achieve the rate listed in the
binding. We also treat each individual timer as a separate
hardware component, when in reality there is one timer block
(that may be duplicated per cpu) with multiple timers within it.
Depending on the version of the hardware there can be one or two
general purpose timers, status and divider control registers, and
an entirely different register layout.
In the next patch we'll need to know about the different register
layouts so that we can properly check the status register after
clearing the count. The current binding makes this complicated
because the general purpose timer's reg property doesn't indicate
where that status register is, and in fact it is beyond the size
of the reg property.
Clean all this up by just having one node for the timer hardware,
and describe all the interrupts and clock frequencies supported
while having one reg property that covers the entire timer
register region. We'll use the compatible field in the future to
determine different register layouts and if we should read the
status registers, etc.

"Things are calming down for arm-soc as well. This set of bug fixes is
dominated in size by the at91 platform bug fixes. Some of them were
meant to go through the framebuffer tree during the merge window, but
since the framebuffer maintainer could not be reached, I offered to
take them here. The other notable at91 change is the addition of
pinctrl definitions to fix the NAND controller.
The rest are mostly simple regression fixes:
- Our removal of VIRT_TO_BUS conflicted with Stephen Rothwell's
renaming of the Kconfig symbol. You will get a trivial merge
conflict here, we still want to remove it.
- missing bits for clocks on imx and s5pv210
- missing header inclusions in mmp and shmobile
- typos in s5pv210 camera and vt8500 clock support code

Provide alternate board code for the kzm9g to demonstrate
how DT may be used given the current state of driver
device tree support. This is intended to act as a reference
for mach-shmobile developers.
Some notes:
* Brings up the GIC interrupt handler using device tree
* Brings up the following device using device tree:
- MMCIF (MMC)
* Does not bring up the INTC interrupt controller at all,
thus external devices may not be used. In particular,
the SMSC ethernet device may not be used and thus
NFS root may not be used.
* Uses existing C code and not device tree to initialise the following,
which are needed for a working board:
- SCIF (Serial)
- CMT (Clock)
- PFC (GPIO)
To use this alternate board code instead of the normal board code,
CONFIG_MACH_KZM9G_REFERENCE should be selected in the kernel config.
And the sh73a0-kzm9g-reference.dtb flattened device tree blob should be used.

Instead of giving zero support of uncompress debug for multiplatform
build, the patch turns uncompress debug into one part of DEBUG_LL
support. When DEBUG_LL is turned on for a particular platform,
uncompress debug works too for that platform.
OMAP and Tegra are exceptions here. OMAP low-level debug code places
data in the .data section, and that is not allowed in decompressor.
And Tegra code has reference to variable that's unavailable in
decompressor but only in kernel. That's why Kconfig symbol
DEBUG_UNCOMPRESS controlling multiplatform uncompress debug support is
defined with !DEBUG_OMAP2PLUS_UART && !DEBUG_TEGRA_UART.
It creates arch/arm/boot/compressed/debug.S with CONFIG_DEBUG_LL_INCLUDE
included there, implements a generic putc() using those macros, which
will be built when DEBUG_UNCOMPRESS is defined.

Following the approach handling DEBUG_LL inclusion, the patch creates
a Kconfig symbol CONFIG_UNCOMPRESS_INCLUDE for choosing the correct
uncompress header. For traditional build, mach/uncompress.h will be
included in arch/arm/boot/compressed/misc.c. For multiplatform build,
debug/uncompress.h which contains a suite of empty functions will be
used. In this way, a platform with particular uncompress.h
implementation could choose its own uncompress.h with this Kconfig
option.
