[PATCH v9 1/9] dt-bindings: mfd: mt6397: Add MT6392 PMIC
From: Luca Leonardo Scorcia <hidden>
Date: 2026-08-20 12:26:10
Also in:
linux-devicetree, linux-gpio, linux-input, linux-mediatek, linux-pm, lkml
Subsystem:
mediatek board level shutdown drivers, mediatek pmic led driver, multifunction devices (mfd), open firmware and flattened device tree bindings, the rest · Maintainers:
Sen Chu, Sean Wang, Macpaul Lin, Lee Jones, Rob Herring, Krzysztof Kozlowski, Conor Dooley, Linus Torvalds
Describe the MT6392 PMIC and its RTC and regulator devices. This device is mostly based on MT6323 with some similarities to MT6397 and is usually found on boards using the MT8516/MT8167 SoC.
