Broadcom BCM7038 PWM controller (BCM7xxx Set Top Box PWM controller)



Required properties:



- compatible: must be "brcm,bcm7038-pwm"

- reg: physical base address and length for this controller

- #pwm-cells: should be 2. See pwm.txt in this directory for a description

  of the cells format

- clocks: a phandle to the reference clock for this block which is fed through

  its internal variable clock frequency generator





Example:



	pwm: pwm@f0408000 {

		compatible = "brcm,bcm7038-pwm";

		reg = <0xf0408000 0x28>;

		#pwm-cells = <2>;

		clocks = <&upg_fixed>;

	};
