Hmm yeah there are slight variations to my signature it seems :)

I guess I have no idea at this point with no documentation. I'll
just drop the comments for now for the mystery registers.

OK will drop for now.

Yup thanks, also can use __func__ or just driver name.

Heheh yeah that looks really weird :) I guess I was too chicken to mess
with the calibration for the battery ADCs earlier so I tried to keep it
as it was in the Motorola driver. But now things are working and I can
compare the results so it should not be a problem.

Yeah so it seems, I'll take a look.

Thanks yes. It was Kelvins in the Motorola driver.
Will fix up the rest of your comments and repost. Thanks for looking
and thanks for the good comments.
