Otherwise the patch looks fine to me. Best regards Uwe

I'm not the one who will apply this patch, so I cannot say. Having said that, I wonder who will apply. Will this go via the arm tree, or via pwm? Best regards Uwe

That leaves the bindings as the, "no idea which one". I wouldn't mind hearing from marcan or Krzysztof as to what their thoughts are on how to send it properly.

The usual process is to take the dt-binding changes and the driver through the subsystem tree (I guess pwm in this case) and the changes to the device trees themselves through our asahi-soc and then through Arnd’s soc tree.
