-Rockchip PWM controller
-
-Required properties:
- - compatible: should be "rockchip,<name>-pwm"
- "rockchip,rk2928-pwm": found on RK29XX,RK3066 and RK3188 SoCs
- "rockchip,rk3288-pwm": found on RK3288 SOC
- "rockchip,rv1108-pwm", "rockchip,rk3288-pwm": found on RV1108 SoC
- "rockchip,vop-pwm": found integrated in VOP on RK3288 SoC
- - reg: physical base address and length of the controller's registers
- - clocks: See ../clock/clock-bindings.txt
- - For older hardware (rk2928, rk3066, rk3188, rk3228, rk3288, rk3399):
- - There is one clock that's used both to derive the functional clock
- for the device and as the bus clock.
- - For newer hardware (rk3328 and future socs): specified by name
- - "pwm": This is used to derive the functional clock.
- - "pclk": This is the APB bus clock.
- - #pwm-cells: must be 2 (rk2928) or 3 (rk3288). See pwm.yaml in this directory
- for a description of the cell format.
-
-Example:
-
- pwm0: pwm@20030000 {
- compatible = "rockchip,rk2928-pwm";
- reg = <0x20030000 0x10>;
- clocks = <&cru PCLK_PWM01>;
- #pwm-cells = <2>;
- };
