arm64: dts: ti: k3-am642-evm/sk: Set serial console settings for stdout-path

[PATCH] arm64: dts: ti: k3-am642-evm/sk: Set serial console settings for stdout-path

Posted by Jonathan Humphreys 1 year, 6 months ago

Set serial console UART settings in the DT so that generic distros will
work even if the OS loader doesn't explicitly pass it.

let the baudrate and uart settings be set by userspace as desired. Also
