+Realtek RTL8186 SoC timer
+
+Required properties:
+
+- compatible : Should be "realtek,rtl8186-timer".
+- reg : Specifies base physical address and size of the registers.
+- interrupts : The interrupt number of the timer.
+- clocks: phandle to the source clock (usually a 22 MHz fixed clock)
+
+Example:
+
+timer {
+	compatible = "realtek,rtl8186-timer";
+	reg = <0x1d010050 0x30>;
+	interrupts = <0>;
+	clocks = <&sysclk>;
+};
