This series takes it from there and implements the binding that was
discussed in https://patchwork.kernel.org/patch/7293991/. In this new
binding the backlight device is a child of the LED controller instead of
being another platform device that uses a phandle to reference a LED.
Other option would be to have backlight trigger. What are
advantages/disadvantages relative to that?

I don't know how this would fit in the model where multiple panels are used, each with its own backlight.

Also the notification is only about blanking.
