Hi Jonathan,

I agree that it would be better to specify the exact PMIC models, however
'similar' wording might be a bit misleading here. As far as I know,
the mt6363 and mt6373 use SPMI, while mt635x (and older models, like
most of the mt63xx series) use PWRAP (a custom SPI-based protocol).
The mt6323 has an older AUXADC revision which is not compatible
with the mt635x driver.

Would you prefer more explicit list like 'MT6323, MT6350 series, MT6363
and MT6373 PMIC AUXADC'? It's a bit mess because some mt63xx
(like mt6333) are sub-PMICs and use I2C instead of PWRAP.
