Allwinner A1X SoCs Timer Controller

Required properties:

- compatible : should be one of the following:

              "allwinner,sun4i-a10-timer"

              "allwinner,suniv-f1c100s-timer"

- reg : Specifies base physical address and size of the registers.

- interrupts : The interrupt of the first timer

- clocks: phandle to the source clock (usually a 24 MHz fixed clock)

Example:

timer {

	compatible = "allwinner,sun4i-a10-timer";

	reg = <0x01c20c00 0x400>;

	interrupts = <22>;

	clocks = <&osc>;
