If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. commit 4bf04e8c2e6ccef318dfc13a96d1bf8afa24a685 Author: Alex Bee <knaerzche@xxxxxxxxx> Date: Sat Jun 19 14:13:06 2021 +0200 arm64: dts: rockchip: Re-add regulator-always-on for vcc_sdio for rk3399-roc-pc [ Upstream commit eb607cd4957fb0ef97beb2a8293478be6a54240a ] Re-add the regulator-always-on property for vcc_sdio which supplies sdmmc, since it gets disabled during reboot now and the bootrom expects it to be enabled when booting from SD card. This makes rebooting impossible in that case and requires a hard reset to boot again. Fixes: 04a0077fdb19 ("arm64: dts: rockchip: Remove always-on properties from regulator nodes on rk3399-roc-pc.")
