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>;

		};

	};
