[PATCH v1 4/4] arm64: dts: mediatek: Add ADC node on MT6357, MT6358, MT6359 PMICs

From: AngeloGioacchino Del Regno
Date: Thu May 30 2024 - 05:35:40 EST


Add support for the ADC on MT6357/8/9 and keep it default enabled
as this IP is always present on those PMICs.
Users may use different IIO channels depending on board-specific
routing.
