Here should be a ref to LED common.yaml:

What does this mean? Is this connected via uart? Why not name it
`baud`? I realize that `current-speed` is used in other device trees
(and `baud` as well), but what "current" is this? I don't suppose this
means electric current :)

Have you passed these via dt_binding_check?
