    Subject[PATCH 5.10 234/243] arm64: dts: rockchip: Re-add regulator-always-on for vcc_sdio for rk3399-roc-pc
    Date
    From: Alex Bee <knaerzche@gmail.com>

    [ 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.")
