Honestly I do not understand this patch. It seems to implement a pin
controller and using it in nonstandard ways.

If something implements the pin controller driver API it should be
used as such IMO, externally. This seems to be using it do relay
calls to itself which seems complicated, just invent something
locally in the driver in that case? No need to use pin control?

Can you explain why this LED driver needs to implement a pin
controller?
