ae24c26327 ARM: S3C64XX: Refresh Cragganmore support
The original Cragganmore code was submitted while new code was being
refused for mainline. This patch was unexpectedly merged upstream but
development had continued in the expectation that the code would be
resubmitted later so no split patches were maintained. This patch
synchronises that work with the recently merged driver.

The main changes are fleshing out of the PMIC and audio integration for
the system, including addition of the Dallas Dhu and Tobermory audio
modules, plus some minor updates to account for revision 2 hardware.

f462904ef1 ARM: SAMSUNG: use regulator VDD for ADC
This patch allows the Samsung ADC driver to enable VDD regulator
at probe and resume and to disable at exit and suspend.
In a platform where ADC's VDD regulator is not "always-on", this
control is required although this patch does not provide fine-grained
power control (turning on the regulator only when being accessed).

However, if VDD regulator ("vdd" for the adc device) is not provided,
the regulator control will not be activated because there are platforms
that do not provide regulator for ADC device.

arch_initcall has been modified to module_init in order to allow
regulators to be available at probe.

aab74d3e75 ARM: EXYNOS4: Add support external GIC
For full support of power modes, this patch adds implementation
external GIC on EXYNOS4.

External GIC of Exynos4 cannot support register banking so
several interrupt related code for CPU1 should be different
from that of CPU0.

540b573875 ARM: 6999/1: head, zImage: Always Enter the kernel in ARM state
Currently, the documented kernel entry requirements are not
explicit about whether the kernel should be entered in ARM or
Thumb, leading to an ambiguitity about how to enter Thumb-2
kernels.  As a result, the kernel is reliant on the zImage
decompressor to enter the kernel proper in the correct instruction
set state.

This patch changes the boot entry protocol for head.S and Image to
be the same as for zImage: in all cases, the kernel is now entered
in ARM.

Documentation/arm/Booting is updated to reflect this new policy.

A different rule will be needed for Cortex-M class CPUs as and when
support for those lands in mainline, since these CPUs don't support
the ARM instruction set at all: a note is added to the effect that
the kernel must be entered in Thumb on such systems.

4348810a24 ARM: btc: avoid invalidating the branch target cache on kernel TLB maintanence
Kernel space needs very little in the way of BTC maintanence as most
mappings which are created and destroyed are non-executable, and so
could never enter the instruction stream.

The case which does warrant BTC maintanence is when a module is loaded.
This creates a new executable mapping, but at that point the pages have
not been initialized with code and data, so at that point they contain
unpredictable information.  Invalidating the BTC at this stage serves
little useful purpose.

Before we execute module code, we call flush_icache_range(), which deals
with the BTC maintanence requirements.  This ensures that we have a BTC
maintanence operation before we execute code via the newly created
mapping.

04ee585495 spi/imx: use soc name in spi device type naming scheme
Software defined version number is not stable enough to be used
in device type naming scheme.  The patch changes it to use implicit
soc name for spi device type definition.  In this way, we can easily
align the naming scheme with device tree binding, which comes later.

It removes fifosize from spi_imx_data and adds devtype there, so that
fifosize can be set in an inline function according to devtype.
Also, cpu_is_mx can be replaced by inline functions checking devtype.

5ca80817e2 ARM / shmobile: Return -EBUSY from A4LC power off if A3RV is active
Since the A4LC should only be powered off if the A3RV is off, make
the A4LC's power down routine return -EBUSY if A3RV is not off to
indicate to the core that it doesn't want to power off the domain in
that case.  This will cause the core to regard A4LC as active, so
the pm_genpd_poweron() in pd_power_down_a3rv() is not necessary any
more.

f7d770790f [CPUFREQ] Move ARM Samsung cpufreq drivers to drivers/cpufreq/
According to discussion of the ARM arch subsystem migration,
ARM cpufreq drivers move to drivers/cpufreq. So this patch
adds Kconfig.arm for ARM like x86 and adds Samsung S5PV210
and EXYNOS4210 cpufreq driver compile in there.
As a note, otherw will be moved.
