From 2b703592b72dbdbdd574181cbfdeea411988a317 Mon Sep 17 00:00:00 2001 From: Monish Chunara Date: Mon, 26 Oct 2026 17:26:11 +0530 Subject: [PATCH] FROMLIST: arm64: dts: qcom: talos-lyra-evk: fix sdhc_2 vqmmc-supply for UHS-I mode SD card is detected as SDHS instead of UHS-I because sdhc_2 was configured with vreg_s4a as vqmmc-supply, which cannot switch between 1.8V and 3.3V. Switch vqmmc-supply to vreg_l2a and update its voltage range to 1800000-2960000 uV to enable proper UHS-I signaling.
