I see that you are sorting alphabetically using the node name but for
example in pinctrl lines we were sorting using the GPIO bank and
offset so if we want to use the same policy here, this should be
green, blue and red.

Either way is good to me though so is up to you.

What is the rationale behind doing this in separate patch, not as part
of 2/5? You can just add new board DTS with all of its features at once,
but maybe I am missing something?

This patch depends on the pinctrl driver, 2/5 on nothing.

By keeping it a separate patch it was intended to go in more quickly
(clear fail there ;)) and it's easier to review the actual changes -
squashing is always easier than picking apart.

Thanks for your review! Both me and Ben have follow-ups once this moves
forward.

Kind regards,
Andreas

OK, I'm fine with it.

The patch looks good:

Can you resend everything with the change in chosen/console?
