From c8d29601fea3080a42731e8535b929a93afa107e Mon Sep 17 00:00:00 2001 From: Philippe Schenker Date: Tue, 9 Jan 2024 13:16:27 +0100 Subject: [PATCH] arm64: dts: imx8mp-verdin: Label ldo5 and link to usdhc2 This commit labels LDO5 as `reg_vdd_sdio` in `imx8mp-verdin.dtsi` to facilitate changing its voltage to 1.8V, necessary for an SDIO peripheral that requires 1.8V at default and high-speed modes. Additionally, it links `reg_vdd_sdio` to `&usdhc2`, aligning with the hardware configuration specified in the datasheet.
