[PATCH v3 0/9] Add support for mt6392 PMIC

[Luca Leonardo Scorcia]

The MediaTek mt6392 PMIC is usually found on devices powered by
the mt8516/mt8167 SoC, and is yet another mt6323/mt6397 variant.

This series is mostly based around patches submitted a couple
years ago by Fabien Parent and not merged and from Val Packett's
submission from Jan 2025 that included extra cleanups, fixes, and a
new dtsi file similar to ones that exist for other PMICs. Some
comments weren't addressed and the series was ultimately not merged.

This series only enables four functions: regulators, keys, pinctrl
and RTC.

I added a handful of device tree improvements to fix some dtbs_check
errors and addressed the comments from last year's reviews.
The series has been tested on Xiaomi Mi Smart Clock x04g. In order for
pinctrl to probe successfully patch [1] has to be merged too, but
each patch code has no dependency on the other.

v3: Added pinctrl device, changed mt6397-rtc fallback to mt6323-rtc,
    added schema for regulators and fixed checkpatch issues.
v2: Review feedback - replaced explicit compatibles with fallbacks
