Hi,

This serie cleans and adds regulator support to Panfrost devfreq.
This is mostly based on comment for the freshly introduced lima
devfreq.

We need to add regulator support because on Allwinner the GPU OPP
table defines both frequencies and voltages.

First patches [01-07] should not change the actual behavior
and introduce a proper panfrost_devfreq struct.

Regards,
Clément
