The MediaTek mt6397 PMIC has a 10-bit AUXADC that nothing in-tree can
reach. On boards built around it that ADC is the only path to the battery:
the SoC's AUXADC is wired to board thermistors, and the charger ICs these
boards use have no ADC at all, so without it there is no pack voltage and
no state of charge.
Hi Ryan,

Please slow down between new versions. Unless a maintainer is specifically
asking for a quick turn around (sometimes happen very late in a series) at
least a week is typical time to allow multiple reviews to come in
and hence save on effort all round.

Hi Jonathan,

Got it, thanks for being patient with me while I'm learning the kernel workflow. I'm sure you guys get a lot of newcomers not knowing the ins and outs. Won't happen again.

Best regards,
