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

Pull ARM soc device tree updates from Olof Johansson:
 "Device tree conversion and enablement branch.  Mostly a bunch of new
  bindings and setup for various platforms, but the Via/Winchip VT8500
  platform is also converted over from being 100% legacy to now use
  device tree for probing.  More of that will come for 3.8."

Trivial conflicts due to removal of vt8500 files, and one documentation
file that was added with slightly different contents both here and in
the USb tree.

* Marvell Tauros2 Cache



Required properties:

- compatible : Should be "marvell,tauros2-cache".

- marvell,tauros2-cache-features : Specify the features supported for the

  tauros2 cache.

  The features including

    CACHE_TAUROS2_PREFETCH_ON       (1 << 0)

    CACHE_TAUROS2_LINEFILL_BURST8   (1 << 1)

  The definition can be found at

  arch/arm/include/asm/hardware/cache-tauros2.h



Example:

	L2: l2-cache {

		compatible = "marvell,tauros2-cache";

		marvell,tauros2-cache-features = <0x3>;

	};

* MSM Timer



Properties:



- compatible : Should at least contain "qcom,msm-timer". More specific

  properties such as "qcom,msm-gpt" and "qcom,msm-dgt" specify a general

  purpose timer and a debug timer respectively.



- interrupts : Interrupt indicating a match event.



- reg : Specifies the base address of the timer registers. The second region

  specifies an optional register used to configure the clock divider.



- clock-frequency : The frequency of the timer in Hz.



Optional:



- cpu-offset : per-cpu offset used when the timer is accessed without the

  CPU remapping facilities. The offset is cpu-offset * cpu-nr.



Example:



       timer@200a004 {

               compatible = "qcom,msm-gpt", "qcom,msm-timer";

               interrupts = <1 2 0x301>;

               reg = <0x0200a004 0x10>;

               clock-frequency = <32768>;

               cpu-offset = <0x40000>;

       };



       timer@200a024 {

               compatible = "qcom,msm-dgt", "qcom,msm-timer";

               interrupts = <1 3 0x301>;

               reg = <0x0200a024 0x10>,

                     <0x0200a034 0x4>;

               clock-frequency = <6750000>;

               cpu-offset = <0x40000>;
