- reg: physical base address and length of the controller's registers
- - clocks: phandle and clock specifier of the PWM reference clock
+ - 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): specified by name
+ - "pwm": This is used to derive the functional clock.
+ - "pclk": This is the bus clock.
- #pwm-cells: must be 2 (rk2928) or 3 (rk3288). See pwm.txt in this directory
for a description of the cell format.
