86b7d3f779 SMP support for Armada XP
The purpose of this series is to add the SMP support for the Armada XP
 SoCs. Beside the SMP support itself brought by the last 3 commits,
 this series also adds the support for the coherency fabric unit and
 the power management service unit.
 
 The coherency fabric is responsible for ensuring hardware coherency
 between all CPUs and between CPUs and I/O masters. This unit is also
 available for Armada 370 and will be used in an incoming patch set
 for hardware I/O cache coherency.
 
 The power management service unit is responsible for powering down and
 waking up CPUs and other SOC units.

42db1215ee arm: mvebu: remove 'clock-frequency' properties from Armada 370/XP Ethernet nodes
The mvneta driver for the Marvell Armada 370/XP Ethernet devices has
gained proper clock framework integration, and the corresponding
Device Tree nodes now have a correct 'clocks' pointer.

The 'clock-frequency' properties in the various .dts files for Armada
370/XP boards have therefore become useless.

This is 3.8 material.

Changes since v2:

 * Renamed the .dts file to armada-xp-openblocks-ax3-4.dts

 * Removed the compatible string from armada-370-xp.c (which now only
   lists the common SoC compatible string)

Changes since v1:

 * Renamed the board to OpenBlocks AX3-4, since there is a variant
   called AX3-2 which has less RAM, and no mini PCIe port. Requested
   by Andrew Lunn.

 * Fix the amount of memory to 3 GB. In fact, the board has 1 GB
   soldered, and 2 GB in a SODIMM slot (which is therefore
   removable). But as the board is delivered as is, we'll assume it
   has 3 GB of memory by default.

Fixes the following errors:

[    2.324432] omap-mcbsp 49024000.mcbsp: invalid rx DMA channel

Which is because we failed to link the sidetone hwmod for McBSP2/3. The
missing sidetone hwmod link will prevent omap_device_alloc() to append the
DMA resources since we - accidentally - end up having the same number of
resources provided from DT (IO/IRQ) as we have in hwmod for the McBSP ports
without the ST resources.

Since the maximum section size on mach-exynos is set to 256MiB, boards
with memory configuration defined using sections bigger than 256MiB will

This patch modifies the dts file of Samsung Trats board to define four
sections of 256MiB instead of two of 512MiB to fix the boot problem.

Commit 9e3c0066 (ARM: dts: imx6q-arm2: add pinctrl for uart and enet)
defines NANDF_CS pins as gpio in 'hog', assuming these two pins are
always used by usdhc3 in gpio mode as card-detection and
write-protection on ARM2 board.  But it's not true.  These pins are
shared by usdhc3 and gpmi-nand.  We should have the pins functional
for gpmi-nand when usdhc3 is disabled.

Move the pins out of 'hog', so that pins only work in gpio mode as CD
and WP when usdhc3 is enabled, and otherwise they are available for
gpmi-nand.

12250d843e Merge branch 'i2c-embedded/for-next' of git://git.pengutronix.de/git/wsa/linux
Pull i2c-embedded changes from Wolfram Sang:
 "The changes for i2c-embedded include:

   - massive rework of the omap driver
   - massive rework of the at91 driver.  In fact, the old driver gets
     removed; I am okay with this approach since the old driver was
     depending on BROKEN and its limitations made it practically
     unusable, so people used bitbanging instead.  But even if there are
     users, there is no platform_data or module parameter which would
     need to be converted.  It is just another driver doing I2C
     transfers, just way better.  Modifications of arch/arm/at91 related
     files have proper acks from the maintainer.
   - new driver for R-Car I2C
   - devicetree and generic_clock conversions and fixes
   - usual driver fixes and changes.

  The rework patches have come a long way and lots of people have been
  involved in creating/testing them.  Most patches have been in
  linux-next at least since 3.6-rc5.  A few have been added in the last
  week, I have to admit.

  An unexpected (but welcome :)) peak in private life is the cause for
  that.  The "late" patches shouldn't cause any merge conflicts and I
  will have a special eye on them during the stabilization phase.  This
  is an exception and I want to have the patches in place properly in
  time again for the next kernels."

   no longer sets up all pin states before starting the kernel.
 - cpufreq fixes for OMAP (Rafael is on vacation and this was pre-agreed).
 - A longer series of misc regression fixes and cleanups, warning removals,
   etc for OMAP
