From 0000000000000000000000000000000000000000 Mon Sep 17 00:00:00 2001 From: Tianling Shen <cnsztl@gmail.com> Date: Mon Aug 05 16:14:33 2024 +0800 Subject: [PATCH] arm64: dts: rockchip: lower mmc speed for Radxa Rock 5B The previously stated speed of sdr-104 in is too high for the hardware to reliably communicate with some fast SD cards. Rockchip boards have a common bug when operating uhs speed, which will hang the system during a soft reboot. To be on the safe side, lower the speed to workaround.
