Pull pwm updates from Thierry Reding:
 "This round contains a couple of new drivers for the Marvell Berlin
  family of SoCs, various SoCs from Renesas and Broadcom as well as the
  backlight PWM present on MediaTek SoCs.

  Further existing drivers are extended to support a wider range of
  hardware.

  The remaining patches are minor fixes and cleanups across the board.

  Note that one of the patches included in this pull request is against
  arch/unicore32.  I've included it here because I couldn't get a
  response from Guan Xuetao and I consider the change low-risk.
  Equivalent patches have been merged and tested in Samsung and PXA
  trees.  The goal is to finally get rid of legacy code paths that have
  repeatedly been causing headaches"

gk20a is an ARM only GPU, so we can just do the correct thing on
ARM but fail on other architectures. The other option was to use
SWIOTLB as the define, which means phys_to_page exists, but
this seems clearer.
Signed-off-by: Dave Airlie <airlied@redhat.com>

Due to a missing initialization there was no way to map fbdev memory.
Thus for example using the Xserver with the fbdev driver failed.
This fix adds initialization for fix.smem_start and fix.smem_len
in the fb_info structure, which fixes this problem.

All drivers should be using dma_set_mask / pci_set_dma_mask to try to
set the dma mask instead of just querying it.  Without that some iommu
implementations may not work.

pci_dma_supported is removed entirely, but dma_supported stays for
dma_ops implementations for now.

Pull ARM DT updates from Olof Johansson:
 "As usual, this is the massive branch we have for each release.  Lots
  of various updates and additions of hardware descriptions on existing
  hardware, as well as the usual additions of new boards and SoCs.

  This is also the first release where we've started mixing 64- and
  32-bit DT updates in one branch.

  (Specific details on what's actually here and new is pretty easy to
  tell from the diffstat, so there's little point in duplicating listing
  it here)"

Pull ARM SoC driver updates from Olof Johansson:
 "As we've enabled multiplatform kernels on ARM, and greatly done away
  with the contents under arch/arm/mach-*, there's still need for
  SoC-related drivers to go somewhere.

  Many of them go in through other driver trees, but we still have
  drivers/soc to hold some of the "doesn't fit anywhere" lowlevel code
  that might be shared between ARM and ARM64 (or just in general makes
  sense to not have under the architecture directory).

  This branch contains mostly such code:

   - Drivers for qualcomm SoCs for SMEM, SMD and SMD-RPM, used to
     communicate with power management blocks on these SoCs for use by
     clock, regulator and bus frequency drivers.

   - Allwinner Reduced Serial Bus driver, again used to communicate with
     PMICs.

   - Drivers for ARM's SCPI (System Control Processor).  Not to be
     confused with PSCI (Power State Coordination Interface).  SCPI is
     used to communicate with the assistant embedded cores doing power
     management, and we have yet to see how many of them will implement
     this for their hardware vs abstracting in other ways (or not at all
     like in the past).

   - To make confusion between SCPI and PSCI more likely, this release
     also includes an update of PSCI to interface version 1.0.

   - Rockchip support for power domains.

   - A driver to talk to the firmware on Raspberry Pi"

Pull ARM SoC cleanups from Olof Johansson:
 "Again we have a sizable (but not huge) cleanup branch with a net delta
  of about -3k lines.

  Main contents here is:

   - A bunch of development/cleanup of a few PXA boards
   - Removal of bockw platforms on shmobile, since the platform has now
     gone completely multiplatform.  Whee!
   - move of the 32kHz timer on OMAP to a proper timesource
   - Misc cleanup of older OMAP material (incl removal of one board
     file)
   - Switch over to new common PWM lookup support for several platforms

  There's also a handful of other cleanups across the tree, but the
  above are the major pieces"

In commit a1c34a3b ("mm: Don't offset memmap for flatmem") Laura
fixed a problem for Srinivas relating to the bottom 2MB of RAM on an ARM
IFC6410 board.

One small wrinkle on ia64 is that it allocates the node_mem_map earlier
in arch code, so it skips the block of code where "offset" is
initialized.

Move initialization of start and offset before the check for the
node_mem_map so that they will always be available in the latter part of
the function.
