-Atmel PWM controller
-
-Required properties:
-  - compatible: should be one of:
-    - "atmel,at91sam9rl-pwm"
-    - "atmel,sama5d3-pwm"
-    - "atmel,sama5d2-pwm"
-    - "microchip,sam9x60-pwm"
-  - reg: physical base address and length of the controller's registers
-  - #pwm-cells: Should be 3. See pwm.yaml 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>;
-		};
-	};
