From 87b90082179daf87969ad9ff44032acc59d9086a Mon Sep 17 00:00:00 2001 From: Diogo Ivo Date: Mon, 23 Sep 2024 19:24:51 +0100 Subject: [PATCH] arm64: tegra: Add SDMMC sdr104-offsets for Tegra X1 Define the sdr104-specific offsets, preventing the driver from defaulting to the 1.8V offsets, which cause the system to hang during the SDR104 mode calibration. The zeroing of these values was chosen since it restores functionality and no better suggestions are provided by the Tegra X1 TRM.
