1 Rockchip PWM controller
4 - compatible: should be "rockchip,<name>-pwm"
5 "rockchip,rk2928-pwm": found on RK29XX,RK3066 and RK3188 SoCs
6 "rockchip,rk3288-pwm": found on RK3288 SoC
7 "rockchip,vop-pwm": found integrated in VOP on RK3288 SoC
8 "rockchip,rk3328-pwm": found on RK3328 SoC
9 "rockchip,rk3399-pwm", "rockchip,rk3288-pwm": found on RK3399 SoC
10 - reg: physical base address and length of the controller's registers
11 - clocks: See ../clock/clock-bindings.txt
12 - For older hardware (rk2928, rk3066, rk3188, rk3228, rk3288, rk3399):
13 - There is one clock that's used both to derive the functional clock
14 for the device and as the bus clock.
15 - For newer hardware (rk3328): specified by name
16 - "pwm": This is used to derive the functional clock.
17 - "pclk": This is the bus clock.
18 - #pwm-cells: must be 2 (rk2928) or 3 (rk3288). See pwm.txt in this directory
19 for a description of the cell format.
