Linus Torvalds 9638685e32 ARM: SoC driver updates for v4.5
Driver updates for ARM SoCs. Some for SoC-family code under drivers/soc,
 but also some other driver updates that don't belong anywhere else. We also
 bring in the drivers/reset code through arm-soc.
 
 Some of the larger updates:
 
 - Qualcomm support for SMEM, SMSM, SMP2P. All used to communicate with other
   parts of the chip/board on these platforms, all proprietary protocols that
   don't fit into other subsystems and live in drivers/soc for now.
 
 - System bus driver for UniPhier
 - Driver for the TI Wakeup M3 IPC device
 
 - Power management for Raspberry PI
 
 + Again a bunch of other smaller updates and patches.

Linus Torvalds b3a5af435a ARM: DT updates for v4.3
This is the usual large batch of DT updates. Lots and lots of smaller
 changes, some of the larger ones to point out are:
 
 - Rockchip veyron (Chromebook) support, as well as several other new boards
 - DRM support on Atmel AT91SAM9N12EK
 - USB additions on some Allwinner platforms
 - Mediatek MT6580 support
 - Freescale i.MX6UL support
 - Cleanups for Renesas shmobile platforms
 - Lots of added devices on LPC18xx
 - Lots of added devices and boards on UniPhier
 
 There's also some dependent code added here, in particular some branches
 that are primarily merged through the clock tree.

 "Ladies and gentlemen, we proudly announce to you the latest branch of

  No less than twentythree thousand lines of additions! Just imagine the

  hardware such as Rockchip Chromebooks, Freescale i.MX6UL boards or

  For those of you feeling less adventurous, added hardware support on

  of your liking.

  We've got something for everyone here!

Linus Torvalds 102178108e ARM: SoC driver updates for v4.3
Some releases this branch is nearly empty, others we have more stuff. It
 tends to gather drivers that need SoC modification or dependencies such
 that they have to (also) go in through our tree.
 
 For this release, we have merged in part of the reset controller tree
 (with handshake that the parts we have merged in will remain stable),
 as well as dependencies on a few clock branches.
 
 In general, new items here are:
 
 - Qualcomm driver for SMM/SMD, which is how they communicate with the
   coprocessors on (some) of their platforms
 - Memory controller work for ARM's PL172 memory controller
 - Reset drivers for various platforms
 - PMU power domain support for Marvell platforms
 - Tegra support for T132/T210 SoCs: PMC, fuse, memory controller per-SoC support

exposed via the CAR IP block.  This reset line is asserted upon SoC
reset.  Unless something (such as the DFLL driver) deasserts this

Linus Torvalds 1a5700bc2d The clock framework changes for 3.16 are pretty typical: mostly clock
driver additions and fixes. There are additions to the clock core code
 for some of the basic types (e.g. the common divider type has some fixes
 and featured added to it).
 
 One minor annoyance is a last-minute dependency that wasn't handled
 quite right. ba0fae3 in this pull request depends on
 include/dt-bindings/clock/berlin2.h, which is already in your tree via
 the arm-soc pull request. Building for the berlin platform will break
 when the clk tree is built on it's own, but merged into your master
 branch everything should be fine.

Merge tag 'clk-for-linus-3.16' of git://git.linaro.org/people/mike.turquette/linux into next

Pull clock framework updates from Mike Turquette:
 "The clock framework changes for 3.16 are pretty typical: mostly clock
  driver additions and fixes.  There are additions to the clock core
  code for some of the basic types (e.g. the common divider type has
  some fixes and featured added to it).

  One minor annoyance is a last-minute dependency that wasn't handled
  quite right.  Commit ba0fae3b06 ("clk: berlin: add core clock driver
  for BG2/BG2CD") in this pull request depends on
  include/dt-bindings/clock/berlin2.h, which is already in your tree via
  the arm-soc pull request.  Building for the berlin platform will break
  when the clk tree is built on it's own, but merged into your master
  branch everything should be fine"
