Please check this. The actual filenames don't look correct to me.

Can we give a bit of text saying what that is? It's nice if people writing userspace software looking at this don't have to go find the datasheet just to give a human readable description of the channel.

drop _current_ as that's a bit confusing :) Reading returns voltage in uV

Is this measuring output of a regulator which has taken vbus and divided it by 5? I'm rather confused.
