Merge tag 'armsoc-drivers' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc 

Pull ARM SoC driver updates from Olof Johansson:
 "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"

Tegra124 CPU frequency scaling driver bindings

----------------------------------------------



Both required and optional properties listed below must be defined

under node /cpus/cpu@0.



Required properties:

- clocks: Must contain an entry for each entry in clock-names.

  See ../clocks/clock-bindings.txt for details.

- clock-names: Must include the following entries:

  - cpu_g: Clock mux for the fast CPU cluster.

  - cpu_lp: Clock mux for the low-power CPU cluster.

  - pll_x: Fast PLL clocksource.

  - pll_p: Auxiliary PLL used during fast PLL rate changes.

  - dfll: Fast DFLL clocksource that also automatically scales CPU voltage.

- vdd-cpu-supply: Regulator for CPU voltage



Optional properties:

- clock-latency: Specify the possible maximum transition latency for clock,

  in unit of nanoseconds.



Example:

--------

cpus {

	#address-cells = <1>;

	#size-cells = <0>;
