Please do not submit new versions of already applied patches, please submit incremental updates to the existing code. Modifying existing commits creates problems for other users building on top of those commits so it's best practice to only change pubished git commits if absolutely essential.

Should I send a v4 to fix that? If there are any changes in this version then yes, if it's identical no.

I will send a v4 with the aforemenetioned fix as a separated commit! - Angelo

Implement {get,set}_voltage_sel, list_voltage, map_voltage with the useful regulator regmap helpers in order to be able to manage the voltage of LAB (positive) and IBB (negative) regulators. In particular, the supported ranges are the following: - LAB (pos): 4600mV to 6100mV with 100mV stepping, - IBB (neg): -7700mV to -1400mV with 100mV stepping.
