+Ingenic JZ47xx PWM Controller
+=============================
+
+Required properties:
+- compatible: One of:
+ * "ingenic,jz4740-pwm"
+ * "ingenic,jz4770-pwm"
+ * "ingenic,jz4780-pwm"
+- #pwm-cells: Should be 3. See pwm.txt in this directory for a description
+ of the cells format.
+- clocks : phandle to the external clock.
+- clock-names : Should be "ext".
+
+
+Example:
+
+ pwm: pwm@10002000 {
+ compatible = "ingenic,jz4740-pwm";
+ reg = <0x10002000 0x1000>;
+
+ #pwm-cells = <3>;
+
+ clocks = <&ext>;
+ clock-names = "ext";
+ };
