[PATCH v4 4/6] arm64: dts: ti: k3-j784s4: Add Main CPSW2G node

From: Chintan Vankar
Date: Wed Jan 31 2024 - 05:17:17 EST


From: Siddharth Vadapalli <s-vadapalli@xxxxxx>

Add the device-tree nodes for the Main CPSW2G instance and enable it.

Add alias for the Main CPSW2G port to enable Linux to fetch MAC Address
for the port directly from U-Boot.
