Merging one more branch wouldn't be a problem, but we'll take care of that
later.

For now, would it be possible to rename the subdir to "pmic" instead of
"pmic_opregion"?  The "_opregion" part doesn't seem to add much value here.

And can the names of the files be somewhat shorter too?  Like "intel_pmic.[h][c]"
and "intel_pmic_crc.c"?
