Current dts files with 'pwm' nodes are manually verified.
In order to automate this process pwm-rockchip.txt
has to be converted to yaml.

Changed V2:
  changed schema for clocks and clock-names

Hi

This tags version 2 with a little mistake instead of version 3?
Is that correct?

-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>;
-	};
