Matthew Gerlach says:

====================
arm64: dts: socfpga: enable ethernet support for Agilex5

This patch set enables ethernet support for the Agilex5 family of SOCFPGAs,
and specifically enables gmac2 on the Agilex5 SOCFPGA Premium Development
Kit.

Patch 1 defines Agilex5 compatibility string in the device tree bindings.

Patch 2 add the new compatibility string to dwmac-socfpga.c.
