X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=13d4890ca951d8aa6b43e1f03d5f44fe5451d6ec;p=thirdparty%2Flinux.git

arm64: dts: freescale: imx95-verdin: Split UART_2 pinctrl group

Some carrier board reuse the UART_2 control signals as GPIO, split
the pinctrl RTS/CTS in separated nodes to maximize flexibility.
