Hi Jacek,

Only DT bindings of LED class drivers should be placed in
Documentation/devicetree/bindings/leds. Please move it to the
media bindings.

that's where I placed it first, but Rob asked me to put it in the
LED directory and Cc the LED mailining list.

That's the discussion of the version 2:

Rob, Jacek, could you please agree where I can put the binding?

Thanks,
Andi
