Rockchip PWM controller
Required properties:
- - compatible: should be "rockchip,rk2928-pwm"
- - reg: physical base address and length of the controller's registers
- - clocks: phandle and clock specifier of the PWM reference clock
- - #pwm-cells: should be 2. See pwm.txt in this directory for a
- description of the cell format.
+- compatible: should be "rockchip,<name>-pwm"should be one of following:
