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

Signed-off-by: Johan Jonker <jbx6244@gmail.com>

For some SoC nodes this patch serie generates notifications
for undocumented "interrupts" properties shared between
PWM channels till there is consensus of what to do with it or
someone makes a solution for the whole PWM block.

Changed V3:
  fix mistake with compatibles introduced in V2
Changed V2:
  changed schema for clocks and clock-names

Heiko, do you want to pick up patches 1 & 2 into your tree along with 3 & 4? If so:

however you like :-)

I can pick up everything for 5.14 for sure.

Depending on your tree-schedule for the merge-window, you could also pick
up all 4 with my:

-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 {
