+Atmel PWM controller
+
+Required properties:
+ - compatible: should be one of:
+ - "atmel,at91sam9rl-pwm"
+ - "atmel,sama5d3-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.
+
+Example:
+
+ pwm0: pwm@f8034000 {
+ compatible = "atmel,at91sam9rl-pwm";
+ reg = <0xf8034000 0x400>;
+ #pwm-cells = <3>;
+ };
+
+ pwmleds {
+ compatible = "pwm-leds";
+
+ d1 {
+ label = "d1";
+ pwms = <&pwm0 3 5000 0>
+ max-brightness = <255>;
+ };
+
+ d2 {
+ label = "d2";
+ pwms = <&pwm0 1 5000 1>
+ max-brightness = <255>;
+ };
+ };
