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.

+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 :
+ scu: system-clk-controller@17000000 {
+ compatible = "apm,xgene-scu","syscon";
+ reg = <0x0 0x17000000 0x0 0x400>;
+ };
