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.

Rockpro64 board is similar to firefly rk-3399 board. DTS is taken from

with recent additions to the pwm-backlight we shouldn't need the
long brightness-levels table and default-brightness-level anymore.
some device support is also needs to be added in this dts. In upcoming
patch-sets I will update those changes.
