| Subject: arm64: dts: rockchip: Re-add regulator-always-on for vcc_sdio for |
| rk3399-roc-pc |
| |
| 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. |
