+Microchip AT91 PWM controller for SAMA5D2
+
+Required properties:
+ - compatible: Should be "atmel,sama5d2-pwm"
+ - reg: Physical base address and length of the controller's registers.
+ - clocks: Should contain a clock identifier for the PWM's parent clock.
+ - #pwm-cells: Should be 3.
+
+Example:
+
+pwm0: pwm@f802c000 {
+ compatible = "atmel,sama5d2-pwm";
+ reg = <0xf802c000 0x4000>;
+ clocks = <&pwm_clk>;
+ #pwm-cells = <3>;
+};
