[PATCH] arm64: dts: ti: k3-j722s-evm: Enable main_uart5
Posted by Bhavya Kapoor 1 year, 6 months ago 
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.

Hi all, please ignore this patch as main_uart5 needs to be kept 
reserved. I will send another patch for the same
