-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>;
- };
