From a10ff5b8cf862cebc24bd3fff9f260451b9d3b87 Mon Sep 17 00:00:00 2001 From: Krzysztof Kozlowski Date: Wed, 26 Oct 2022 16:03:55 -0400 Subject: [PATCH] arm64: dts: qcom: sm8450: disable SDHCI SDR104/SDR50 on all boards [ Upstream commit 9d561dc4e5cc31e757f91eb7bb709d2e2a8c9ce0 ] SDHCI on SM8450 HDK also has problems with SDR104/SDR50: mmc0: card never left busy state mmc0: error -110 whilst initialising SD card so I think it is safe to assume this issue affects all SM8450 boards. Move the quirk disallowing these modes to the SoC DTSI, to spare people working on other boards the misery of debugging this issue.
