Seems you missed the reference to pwm.yaml.

It is because many pwm yaml files also has no "#pwm-cells" reference, so I
am NOT sure if it is a MUST:

Documentation/devicetree/bindings/pwm/allwinner,sun4i-a10-pwm.yaml
Documentation/devicetree/bindings/pwm/google,cros-ec-pwm.yaml
Documentation/devicetree/bindings/pwm/iqs620a-pwm.yaml
...

I guess we'd better add it.
Let's wait for Rob's feedback.
