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.yaml 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>; };
