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