+Subject: [PATCH] arm64: dts: rockchip: regulator for sd needs to be always on
+ for BPI-R2Pro
+
+With default dts configuration for BPI-R2Pro, the regulator for sd card is
+powered off when reboot is commanded, and the only solution to detect the
+sd card again, and therefore, allow rebooting from there, is to do a
+hardware reset.
+
+Configure the regulator for sd to be always on for BPI-R2Pro in order to
+avoid this issue.
+
