Hello Alexandre,

Thanks for quick check! I'll be off for the rest of the week but I will
re-work this patch at next week :) I agree with you regarding most of
the comments.

I would prefer renaming because it makes it clearly visible which
defines/structs/functions are common for both PMICs and which are PMIC
specific. But I really understand the problem of spotting real changes.
Would it be Ok if I did renaming in separate patch which does not bring
in any other changes - and then the functional changes in separate
patch?
