Linus Walleij already notified me about this. I just wondered why this
is not reflected in:

LICENSES/preferred/GPL-2.0

which seems to state:

Valid-License-Identifier: GPL-2.0-only

https://elixir.bootlin.com/linux/v5.4-rc5/source/LICENSES/preferred/GPL-2.0

I'll change the SPDX for new files for next version.

Ok. So I'll add myself then. Although I am by no means an expert what
comes to binding schemas. I know the device and driver though.

Hmmm. I thought this would depend on rest of the system's DT. Why
should it be same on each board? (I can drop this out though).

I guess it is the LED function definition. Those function/colour
bindings were only added in 5.4-rc1. Do you have them defined in your
build environment at /include/dt-bindings/leds/common.h?

Rest of the comments are clear to me :)
