+ARM sp804 Dual Timers
+---------------------------------------
+
+Required properties:
+- compatible: Should be "arm,sp804" & "arm,primecell"
+- interrupts: Should contain the list of Dual Timer interrupts
+	interrupts = <0 0 4>, <0 1 4>;
+- reg: Should contain location and length for dual timer register.
+- clocks: clock driving the dual timer hardware
+	clocks = <&timclk0 &timclk1>;
+
+Optional properties:
+- arm,sp804-clocksource: Should contain the register offset of TIMER1 or
+  TIMER2 in Dual Timer Controller.
+	arm,sp804-clocksource = <0x20>;
+
+Example:
+
+	timer0: timer@fc800000 {
+		compatible = "arm,sp804", "arm,primecell";
+		reg = <0xfc800000 0x1000>;
+		/* timer00 & timer01 */
+		interrupts = <0 0 4>, <0 1 4>;
+		clocks = <&timclk0 &timclk1>;
+		clock-names = "apb_pclk";
+		status = "disabled";
