+Rockchip PWM controller
+
+Required properties:
+ - compatible: should be "rockchip,rk2928-pwm"
+ - reg: physical base address and length of the controller's registers
+ - clocks: phandle and clock specifier of the PWM reference clock
+ - #pwm-cells: should be 2. See pwm.txt in this directory for a
+ description of the cell format
+
+Example:
+
+ pwm0: pwm@20030000 {
+ compatible = "rockchip,rk2928-pwm";
+ reg = <0x20030000 0x10>;
+ clocks = <&cru PCLK_PWM01>;
+ #pwm-cells = <2>;
+ };
