[PATCH 0/7] APM X-Gene SoC platform device tree cleanup

[Feng Kan]

This sums up the dts changes of the recent committed drivers into the kernel.
This will grant PMU, reboot, USB and gpio functionalities to the platform.

[PATCH 1/7] arm64: dts: Add APM X-Gene USB 2.0 DTS node

[Feng Kan]

This parch adds the device tree nodes for APM X-Gnene USB host controller.
Since X-Gene SOC supports maximum 2 USB ports, 2 dts node are added.

+APM X-GENE SoC series SCU Registers

+This system clock unit contain various register that control block resets,
+clock enable/disables, clock divisors and other deepsleep registers.
+
+Properties:
+ - compatible : should contain two values. First value must be:
+		   - "apm,xgene-scu"
+		second value must be always "syscon".
+
+ - reg : offset and length of the register set.

+Example :

+		reg = <0x0 0x17000000 0x0 0x400>;
