  A slew of changes this release cycle.  The reset driver tree, that we
  merge through arm-soc for historical reasons, is also sizable this
  time around.

  Among the changes:

   - clps711x: Treewide changes to compatible strings, merged here for simplicity.
   - Qualcomm: SCM firmware driver cleanups, move to platform driver
   - ux500: Major cleanups, removal of old mach-specific infrastructure.
   - Atmel external bus memory driver
   - Move of brcmstb platform to the rest of bcm
   - PMC driver updates for tegra, various fixes and improvements
   - Samsung platform driver updates to support 64-bit Exynos platforms
   - Reset controller cleanups moving to devm_reset_controller_register() APIs
   - Reset controller driver for Amlogic Meson
   - Reset controller driver for Hisilicon hi6220
   - ARM SCPI power domain support"

2016-07-30T18:32:01+00:00

Pull DeviceTree updates from Rob Herring:

 - remove most of_platform_populate() calls in arch code.  Now the DT
   core code calls it in the default case and platforms only need to
   call it if they have special needs

 - use pr_fmt on all the DT core print statements

 - CoreSight binding doc improvements to block name descriptions

 - add dt_to_config script which can parse dts files and list
   corresponding kernel config options

 - fix memory leak hit with a PowerMac DT

 - correct a bunch of STMicro compatible strings to use the correct
   vendor prefix

 - fix DA9052 PMIC binding doc to match what is actually used in dts
   files

Make mvebu_mbus_syscore_ops static as it does not get
used or declared outside mvebu-mbus.c to fix the following
sparse warning:

plain "u32 *" as it is passed to register access functions. Fix

bus: Add support for Tegra ACONNECT

2016-07-01T14:35:43+00:00

Add a bus driver for the Tegra ACONNECT which is used to interface to
various devices within the Audio Processing Engine (APE). The purpose
of the bus driver is to register child devices that are accessed via
the ACONNECT bus and through the device parent child relationship,
ensure that the appropriate power domain and clocks are enabled for
the ACONNECT when any of the child devices are active. Hence, the
ACONNECT driver simply enables runtime-pm for the ACONNECT device
so that when a child device is resumed, it will enable the power-domain
and clocks associated with the ACONNECT.

Use helper of_platform_default_populate() in linux/of_platform
