Calibration values are 24-bit wide. Those values so far appear to span
only 16 bits but let's not push our luck.

Found while looking at the original Mediatek driver code.

I wonder how much feedback you got on v1 - I didn't even look and will not lose
time with that - but regardless, if you don't add the right people to the Cc field,
I really don't think that you'll ever get your patches reviewed (and probably also
not accepted).

That -- especially if you don't even Cc all the relevant maintainers...!

Please don't suggest to people that commit signers and authors are CCed. 
That results in huge Cc lists of people that probably aren't interested. 
If they are, then they should add themselves to MAINTAINERS.
