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,vop-pwm": found integrated in VOP on RK3288 SoC
- reg: physical base address and length of the controller's registers
- clocks: phandle and clock specifier of the PWM reference clock
- #pwm-cells: must be 2 (rk2928) or 3 (rk3288). See pwm.txt in this directory
for a description of the cell format.
pwm0: pwm@20030000 {
compatible = "rockchip,rk2928-pwm";
reg = <0x20030000 0x10>;
clocks = <&cru PCLK_PWM01>;
#pwm-cells = <2>;
