[PATCH 23/27] arm64: dts: mediatek: Add MT6331 PMIC devicetree

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



MT6331 is the primary PMIC for the MediaTek Helio X10 MT6795 smartphone
platforms: add a devicetree describing its regulators, Real Time Clock
and PMIC-keys.
