+Ingenic JZ47xx SoCs Timer/Counter Unit driver
+---------------------------------------------
+
+Required properties:
+
+- compatible : should be "ingenic,<socname>-tcu". Valid strings are:
+ * ingenic,jz4740-tcu
+ * ingenic,jz4770-tcu
+ * ingenic,jz4780-tcu
+- interrupt-parent : phandle of the TCU interrupt controller.
+- interrupts : Specifies the interrupts the controller is connected to.
+- clocks : List of phandle & clock specifiers for the TCU clocks.
+- clock-names : List of name strings for the TCU clocks.
+
+Example:
+
+/ {
+ mfd@10002000 {
+ compatible = "ingenic,tcu", "simple-mfd", "syscon";
+ reg = <0x10002000 0x1000>;
+
+ tcu_timer: timer {
+ compatible = "ingenic,jz4740-tcu";
+ reg = <0x10002010 0xFF0>;
+
+ clocks = <&tcu 0>, <&tcu 1>, <&tcu 2>, <&tcu 3>,
+ <&tcu 4>, <&tcu 5>, <&tcu 6>, <&tcu 7>;
+ clock-names = "timer0", "timer1", "timer2", "timer3",
+ "timer4", "timer5", "timer6", "timer7";
+
+ interrupt-parent = <&tcu>;
+ interrupts = <0 1 2 3 4 5 6 7>;
+ };
+ };
+};
