8e73e367f7 ARM: SoC cleanups for 3.12
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.

ae3c99a26c ARM: 7806/1: allow DEBUG_UNCOMPRESS for Tegra
DEBUG_UNCOMPRESS was previously disallowed for Tegra due to tegra.S's
use of global data that was not linked into the decompressor. Solve this
by declaring this symbol in tegra.S when it is being built into the
decompressor. For the kernel proper, leave the declaration in
mach-tegra/common.c as explained in the comment.

f8f1279ce0 ARM: debug: provide generic option choices for 8250 and PL01x ports
Provide generic option choices for 8250 and PL01x UART ports; these can
now be selected by UART type rather than asking about the platform.
This means that a kernel configuration user can manually choose the
various parameters of the debug UART without resorting to the platform
having to encode the possible settings.

These two generic options are preferred over further debug entries for
these ports; the existing options which refer back to the 8250 and PL01x
ports are now considered deprecated.

b6992fa9a7 ARM: document DEBUG_UNCOMPRESS Kconfig option
This non-user visible option lacked any kind of documentation.  This
is quite common for non-user visible options; certian people can't
understand the point of documenting such options with help text.

However, here we have a case in point: developers don't understand the
option either, as they were thinking that when the option is not set,
the decompressor should produce no output what so ever.  This is
incorrect, as the purpose of this option is to control whether a
multiplatform kernel uses the kernel debugging macros to produce
output or not.

So let's document this via help rather than commentry to prevent others
falling into this misunderstanding.

Pull ARM updates from Russell King:
 "This contains the usual updates from other people (listed below) and
  the usual random muddle of miscellaneous ARM updates which cover some
  low priority bug fixes and performance improvements.

  I've started to put the pull request wording into the merge commits,
  which are:

   - NoMMU stuff:

     This includes the following series sent earlier to the list:
      - nommu-fixes
      - R7 Support
      - MPU support

     I've left out the ARCH_MULTIPLATFORM/!MMU stuff that Arnd and I
     were discussing today until we've reached a conclusion/that's had
     some more review.

     This is rebased (and re-tested) on your devel-stable branch because
     otherwise there were going to be conflicts with Uwe's V7M work now
     that you've merged that.  I've included the fix for limiting MPU to
     CPU_V7.

   - Huge page support

     These changes bring both HugeTLB support and Transparent HugePage
     (THP) support to ARM.  Only long descriptors (LPAE) are supported
     in this series.

     The code has been tested on an Arndale board (Exynos 5250).

   - LPAE updates

     Please pull these miscellaneous LPAE fixes I've been collecting for
     a while now for 3.11.  They've been tested and reviewed by quite a
     few people, and most of the patches are pretty trivial.  -- Will Deacon.

   - arch_timer cleanups

     Please pull these arch_timer cleanups I've been holding onto for a
     while.  They're the same as my last posting, but have been rebased
     to v3.10-rc3.

   - mpidr linearisation (multiprocessor id register - identifies which
     CPU number we are in the system)

     This patch series that implements MPIDR linearization through a
     simple hashing algorithm and updates current cpu_{suspend}/{resume}
     code to use the newly created hash structures to retrieve context
     pointers.  It represents a stepping stone for the implementation of
     power management code on forthcoming multi-cluster ARM systems.

     It has been tested on TC2 (dual cluster A15xA7 system), iMX6q,
     OMAP4 and Tegra, with processors hitting low-power states requiring
     warm-boot resume through the cpu_resume code path"

42daabf62b ARM SoC late changes
These are changes that arrived a little late before the merge
 window or that have multiple dependencies on previous branches
 so they did not fit into one of the earlier ones. There
 are 10 branches merged here, a total of 39 non-merge commits.
 Contents are a mixed bag for the above reasons:
 
 * Two new SoC platforms: ST microelectronics stixxxx and
   the TI 'Nspire' graphing calculator. These should have
   been in the 'soc' branch but were a little late
 * Support for the Exynos 5420 variant in mach-exynos,
   which is based on the other exynos branches to avoid
   conflicts.

37c5a9f7d7 Merge branch 'sti/soc' into next/late
From Srinivas Kandagatla <srinivas.kandagatla@st.com>:

This patch-set adds basic support for STMicroelectronics STi series SOCs
which includes STiH415 and STiH416 with B2000 and B2020 board support.

STiH415 and STiH416 are dual-core ARM Cortex-A9 CPU, designed for
use in Set-top-boxes. The SOC support is available in mach-sti which
contains support code for STiH415, STiH416 SOCs including the generic
board support.

The reason for adding two SOCs at this patch set is to show that no new
C code is required for second SOC(STiH416) support.

  ARM: stih41x: Add B2020 board support
  ARM: stih41x: Add B2000 board support

fcba914542 ARM: arm-soc platform updates for 3.10, part 3
This is the third and smallest of the SoC specific updates.
 Changes include:
 
 * SMP support for the Xilinx zynq platform
 * Smaller imx changes
 * LPAE support for mvebu
 * Moving the orion5x, kirkwood, dove and mvebu platforms
   to a common "mbus" driver for their internal devices.
 
 It would be good to get feedback on the location of the "mbus"
 driver. Since this is used on multiple platforms may potentially
 get shared with other architectures (powerpc and arm64), it
 was moved to drivers/bus/. We expect other similar drivers to
 get moved to the same place in order to avoid creating more
 top-level directories under drivers/ or cluttering up the
 messy drivers/misc/ even more.

150a8dcf10 ARM: arm-soc board specific changes for 3.10, part 1
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.

   - Error handling cleanups of the IS_ERR_OR_NULL() madness and fixes

56b690481c Merge branch 'samsung/exynos-multiplatform' into next/multiplatform
These patches get us closer to adding multiplatform support on
the Exynos platform, they are part of a longer series of
patches.  This would get all the simple stuff out of the
way, and I don't think there is a big risk of introducing
regressions with these.

A lot of the other patches have already been merged into
subsystem trees. After this series in in arm-soc, what is
left comes down to

* The ASoC conversion to dmaengine won't make it unless someone
  who knows that code better steps up to do it right away. This
  means that we won't have audio in a 3.10 multiplatform kernel
  on Exynos, but it will still work for users that don't enable
  multiplatform.

* The irqchip (combiner), clk and clksource patches are all based
  on top   of other changesets we pulled in from your trees, so I
  would not make them part of the next/multiplatform branch. We can
  apply them on top of the next/drivers branch once they are
  tested successfully.

* A trivial patch is needed in the end to actually make
  CONFIG_ARCH_EXYNOS visible in multiplatform configurations.
  We will do that as a separate patch once everything else is
  there.

a2e4071047 ARM: exynos: move debug-macro.S to include/debug/
The move is necessary to support early debug output on exynos
with multiplatform configurations. This implies also moving the
plat/debug-macro.S file, but we are leaving the remaining users of that
file in place, to avoid adding large numbers of extra configuration
options to Kconfig.debug
