Subject: [PATCH v3 4/5] arm64: tegra: Add vmmc-supply regulator for Jetson AGX Xavier SDMMC1
Date: Wed, 14 Oct 2020 19:56:26 +0200 [thread overview]
Message-ID: <20201014175627.5585-5-tszucs@protonmail.ch> (raw)
In-Reply-To: <20201014175627.5585-1-tszucs@protonmail.ch>
Create regulator for VDD_3V3_SD and add it to SDMMC1. When vmmc-supply is
undefined the initialization sequence specified in aliases is disregarded.
