   4 Subject: [PATCH] arm64: dts: rockchip: regulator for sd needs to be always on
   5  for BPI-R2Pro
   6
   7 With default dts configuration for BPI-R2Pro, the regulator for sd card is
   8 powered off when reboot is commanded, and the only solution to detect the
   9 sd card again, and therefore, allow rebooting from there, is to do a
  10 hardware reset.
  11
  12 Configure the regulator for sd to be always on for BPI-R2Pro in order to
  13 avoid this issue.
