This looks basically good, a couple of minor nits below but nothing
substantial.

This looks like a linear range so could use the linear range helpers
(4.5-6.35V in steps of 0.05V)? Similarly for the LDO.

These names don't correspond to what was in the binding document and
there's a couple of extra LDOs.
