Well, I think the question is if you understand where those numbers come
from and if they make sense. I've not seen the schematic for the board
so I can't comment but it is quite unusual to see ranges listed for so
many supplies, for things like SD it's obviously normal but things like
video_mid are a bit more surprising. Does anything actually vary those
voltages?

The change where you fix up the supply mappings still makes sense of
course.
