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

Pull ARM SoC driver specific changes from Arnd Bergmann:
 "These changes are all driver specific and cross over between arm-soc
  contents and some other subsystem, in these cases cpufreq, crypto,
  dma, pinctrl, mailbox and usb, and the subsystem owners agreed to have
  these changes merged through arm-soc.

  As we proceed to untangle the dependencies between platform code and
  driver code, the amount of changes in this category is fortunately
  shrinking, for 3.11 we have 16 branches here and 101 non-merge
  changesets, the majority of which are for the stedma40 dma engine
  driver used in the ux500 platform.  Cleaning up that code touches
  multiple subsystems, but gets rid of the dependency in the end.

  The mailbox code moved out from mach-omap2 to drivers/mailbox is an
  intermediate step and is still omap specific at the moment.  Patches
  exist to generalize the subsystem and add other drivers with the same
  API, but those did not make it for 3.11."

* Samsung Audio Subsystem Clock Controller
The Samsung Audio Subsystem clock controller generates and supplies clocks
to Audio Subsystem block available in the S5PV210 and Exynos SoCs. The clock
binding described here is applicable to all SoC's in Exynos family.
Required Properties:
- compatible: should be one of the following:
- "samsung,exynos4210-audss-clock" - controller compatible with all Exynos4 SoCs.
- "samsung,exynos5250-audss-clock" - controller compatible with all Exynos5 SoCs.
- reg: physical base address and length of the controller's register set.
- #clock-cells: should be 1.
The following is the list of clocks generated by the controller. Each clock is
assigned an identifier and client nodes use this identifier to specify the
clock which they consume. Some of the clocks are available only on a particular
Exynos4 SoC and this is specified where applicable.
Provided clocks:
Clock ID SoC (if specific)
-----------------------------------------------
mout_audss 0
mout_i2s 1
dout_srp 2
dout_aud_bus 3
dout_i2s 4
srp_clk 5
i2s_bus 6
sclk_i2s 7
pcm_bus 8
sclk_pcm 9
Example 1: An example of a clock controller node is listed below.
clock_audss: audss-clock-controller@3810000 {
compatible = "samsung,exynos5250-audss-clock";
reg = <0x03810000 0x0C>;
#clock-cells = <1>;
};
Example 2: I2S controller node that consumes the clock generated by the clock
controller. Refer to the standard clock bindings for information
about 'clocks' and 'clock-names' property.
