[v2,2/5] arm64: dts: ti: k3-j784s4: Add Main CPSW2G node
Commit Message
From: Siddharth Vadapalli <s-vadapalli@ti.com>
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.

Please do not mix the SoC and evm changes in the same patch.
Also, any benefits of giving the second instance an alias?
