Tool/software:
#1. Can wkup_uart and mcu_uart be used in Linux? I think it is okay, but there is a notes in In k3-j722s-evm.dts, How to enable it for Linux side using?
&wkup_uart0: /*WKUP UART0 is used by DM firmware */
#2. Is there limitation of wkup_uart and mcu_uart usage? like if support DMA, or other limitation?
