Hi!

Yeah, so...

Bindings should go first, they may need to be converted to yml
(devicetree people will know).

Can generic pwm driver be used here?

This is for RGB modules, right? It will need to use multicolor
framework.

"Breathing" will need to be figured out. It should become a trigger.

Is this for phone, btw? If so, which one?

Best regards,
								Pavel
