Some comments, have a look if it is useful...

In rockpie-v1.2-20200427-sch.pdf this led is already called "LED_BLUE",
so comment maybe not needed anymore?

regulator-name above other regulator properties
regulator voltage missing
make things as complete as possible
from fixed-regulator.yaml:
description:
Any property defined as part of the core regulator binding, defined in
regulator.yaml, can also be used. However a fixed voltage regulator is
expected to have the regulator-min-microvolt and regulator-max-microvolt
to be the same.

For Heiko: ?? remove ??
usb3 has no support in mainline.
Regulators not in use are disabled.
For mainline this node has no use....

At the other regulators this is sort below the regulator limits.

use something else

Last numbers in nodenames are more related to the sort order then to
capabillity.
ie: mmc0, mmc1
All usb pin related things here.
