   4 Subject: [PATCH] arm64: dts: rockchip: Add sdmmc related properties on
   5  rk3308-rock-pi-s
   6
   7 Add cap-mmc-highspeed to allow use of high speed MMC mode using an eMMC
   8 to uSD board. Use disable-wp to signal that no physical write-protect
   9 line is present. Also add vcc_io used for card and IO line power as
  10 vmmc-supply.
