main_uart5 node defined in the SoC dtsi file is incomplete and will not be functional unless it is extended with pinmux information at board integration level. Thus, add pinmux for main_uart5 in the board dts file and enable it to make it functional. Signed-off-by: Bhavya Kapoor <b-kapoor@xxxxxx> ---
