   4 Subject: [PATCH] arm64: dts: rockchip: Add pinctrl for UART0 to
   5  rk3308-rock-pi-s
   6
   7 UAR0 CTS/RTS is not wired to any pin and is not used for the default
   8 serial console use of UART0 on ROCK Pi S.
   9
  10 Override the SoC defined pinctrl props to limit configuration of the
  11 two xfer pins wired to one of the GPIO pin headers.
