+Allwinner sun4i and sun7i SoC PWM controller
+
+Required properties:
+ - compatible: should be one of:
+ - "allwinner,sun4i-a10-pwm"
+ - "allwinner,sun7i-a20-pwm"
+ - reg: physical base address and length of the controller's registers
+ - #pwm-cells: should be 3. See pwm.txt in this directory for a description of
+ the cells format.
+ - clocks: From common clock binding, handle to the parent clock.
+
+Example:
+
+ pwm: pwm@01c20e00 {
+ compatible = "allwinner,sun7i-a20-pwm";
+ reg = <0x01c20e00 0xc>;
+ clocks = <&osc24M>;
+ #pwm-cells = <3>;
+ status = "disabled";
+ };
