[PATCH 04/10] arm64: dts: ti: k3-am642-sk: Describe main_uart1 pins
From: Nishanth Menon
Date: Fri Apr 14 2023 - 03:34:02 EST
Describe the main_uart1 pins even though it is a reserved node for
hardware complete description. This is used by other users of device
tree to help configure the SoC per board requirements.
