generally the patch looks great already. Hopefully we will get an Ack
from the dt-maintaintainers for the binding and I noticed two small
issues I'll describe below.

with recent additions to the pwm-backlight we shouldn't need the
long brightness-levels table and default-brightness-level anymore.

Rockpro64 board is similar to firefly rk-3399 board. DTS is taken from
firefly board and it is booting fine with minimal changes.

Should I continue with the rockchip rights or update with the mine copy
rights?

some device support is also needs to be added in this dts. In upcoming
patch-sets I will update those changes.

I guess, you could keep the old one and add a second line for 2018 and
your copyright, as you also added changes to it.
