2bf73dd61a ARM: SoC: late cleanups
These could not be part of the first cleanup branch, because they either
 came too late in the cycle, or they have dependencies on other branches.
 Important changes are:
 
 * The integrator platform is almost multiplatform capable after
   some reorganization (Linus Walleij)
 * Minor cleanups on Zynq (Michal Simek)
 * Lots of changes for Exynos and other Samsung platforms, including
   further preparations for multiplatform support and the clocks bindings
   are rearranged.

Lots of changes specific to one of the SoC families. Some that
 stick out are:
 
 * mach-qcom gains new features, most importantly SMP support for
   the newer chips (Stephen Boyd, Rohit Vaswani)
 * mvebu gains support for three new SoCs: Armada 375, 380 and 385
   (Thomas Petazzoni and Free-electrons team)
 * SMP support for Rockchips (Heiko Stübner)
 * Lots of i.MX changes (Shawn Guo)
 * Added support for BCM5301x SoC (Hauke Mehrtens)
 * Multiplatform support for Marvell Kirkwood and Dove
   (Andrew Lunn and Sebastian Hesselbarth doing the final part
   of a long journey)
 * Unify davinci platforms and remove obsolete ones (Sekhar Nori,

efm32 has no mach/uncompress.h, but we can trivially use
the fallback to the ll_debug code by just allowing this

9d6eccb9cc ARM: davinci: remove tnetv107x support
The tnetv107x support does not compile, and seems to have been broken
for a while with nobody caring to fix it. So far everyone I asked
said it's probably dead and completely unused and will never again
be needed in a future kernel release, so let's delete it.

If someone finds a use for this code later and is able to get it
to work again, we can always revert the removal.

Low-level debugging using the Broadcom Kona UART only makes sense on the
ARCH_BCM_MOBILE platform and would otherwise prevent ARCH_BCM_63XX from

f47671e2d8 Merge branch 'for-linus' of git://git.linaro.org/people/rmk/linux-arm
Pull ARM updates from Russell King:
 "Included in this series are:

   1. BE8 (modern big endian) changes for ARM from Ben Dooks
   2. big.Little support from Nicolas Pitre and Dave Martin
   3. support for LPAE systems with all system memory above 4GB
   4. Perf updates from Will Deacon
   5. Additional prefetching and other performance improvements from Will.
   6. Neon-optimised AES implementation fro Ard.
   7. A number of smaller fixes scattered around the place.

  There is a rather horrid merge conflict in tools/perf - I was never
  notified of the conflict because it originally occurred between Will's
  tree and other stuff.  Consequently I have a resolution which Will
  forwarded me, which I'll forward on immediately after sending this
  mail.

  The other notable thing is I'm expecting some build breakage in the
  crypto stuff on ARM only with Ard's AES patches.  These were merged
  into a stable git branch which others had already pulled, so there's
  little I can do about this.  The problem is caused because these
  patches have a dependency on some code in the crypto git tree - I
  tried requesting a branch I can pull to resolve these, and all I got
  each time from the crypto people was "we'll revert our patches then"
  which would only make things worse since I still don't have the
  dependent patches.  I've no idea what's going on there or how to
  resolve that, and since I can't split these patches from the rest of
  this pull request, I'm rather stuck with pushing this as-is or
  reverting Ard's patches.

  Since it should "come out in the wash" I've left them in - the only
  build problems they seem to cause at the moment are with randconfigs,
  and since it's a new feature anyway.  However, if by -rc1 the
  dependencies aren't in, I think it'd be best to revert Ard's patches"

I resolved the perf conflict roughly as per the patch sent by Russell,
but there may be some differences.  Any errors are likely mine.  Let's
see how the crypto issues work out..

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.

This means that a kernel configuration user can manually choose the

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

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.

fb2af0020a Merge branch 'for-linus' of git://git.linaro.org/people/rmk/linux-arm
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.
 * Various small changes for sh-mobile, ux500 and davinci
 * Common clk support for MSM
 
 Conflicts:
 * In Kconfig.debug, various additions trivially conflict,
   the list should be kept in alphabetical order when
   resolving.
