+Required properties:
+
+- compatible : should be "allwinner,sun4i-a10-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>;
+};
