Pull ARM SoC-specific updates from Arnd Bergmann:
 "This is a larger set of new functionality for the existing SoC
  families, including:

   - vt8500 gains support for new CPU cores, notably the Cortex-A9 based
     wm8850

   - prima2 gains support for the "marco" SoC family, its SMP based
     cousin

   - tegra gains support for the new Tegra4 (Tegra114) family

   - socfpga now supports a newer version of the hardware including SMP

   - i.mx31 and bcm2835 are now using DT probing for their clocks

   - lots of updates for sh-mobile

   - OMAP updates for clocks, power management and USB

   - i.mx6q and tegra now support cpuidle

   - kirkwood now supports PCIe hot plugging

   - tegra clock support is updated

   - tegra USB PHY probing gets implemented diffently"

NVIDIA Tegra20 Clock And Reset Controller
This binding uses the common clock binding:
Documentation/devicetree/bindings/clock/clock-bindings.txt
The CAR (Clock And Reset) Controller on Tegra is the HW module responsible
for muxing and gating Tegra's clocks, and setting their rates.
Required properties :
- compatible : Should be "nvidia,tegra20-car"
- reg : Should contain CAR registers location and length
- clocks : Should contain phandle and clock specifiers for two clocks:
the 32 KHz "32k_in", and the board-specific oscillator "osc".
- #clock-cells : Should be 1.
In clock consumers, this cell represents the clock ID exposed by the CAR.
The first 96 clocks are numbered to match the bits in the CAR's CLK_OUT_ENB
registers. These IDs often match those in the CAR's RST_DEVICES registers,
but not in all cases. Some bits in CLK_OUT_ENB affect multiple clocks. In
this case, those clocks are assigned IDs above 95 in order to highlight
this issue. Implementations that interpret these clock IDs as bit values
within the CLK_OUT_ENB or RST_DEVICES registers should be careful to
explicitly handle these special cases.
The balance of the clocks controlled by the CAR are assigned IDs of 96 and
above.
