nit: the comment above this block (not in the unified diff)
specifically calls out 1.8V. It'd be nice if you updated the comment
since it's no longer fixed at 1.8V.

nit: "else if" instead of "if"?


I guess I'm a little late since I think this already got applied, but
all the above are nits. Maybe you could send a follow-up patch to
address them?
