[PATCH v2 2/5] arm64: dts: ti: k3-j784s4: Add Main CPSW2G node

From: Jayesh Choudhary
Date: Fri Apr 14 2023 - 11:16:23 EST


From: Siddharth Vadapalli <s-vadapalli@xxxxxx>

J784S4 SoC has a Main CPSW2G instance of the CPSW Ethernet Switch.

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