[PATCH 1/2] arm/arm64: dts: Enable 2.5G Ethernet port on CN9130-CRB

From: Chris Packham
Date: Thu Oct 07 2021 - 19:06:37 EST


Enable the 2.5G Ethernet port by setting the status to "okay" and the
phy-mode to "2500base-x" on the cn9130-crb boards. Tested on a
CN9130-CRB-A.

The Marvell SDK adds 2500base-t and uses it in the equivalent dtsi but
looking at the documentation for both the SoC and the PHY I think
2500base-x is correct for the system interface (the line side is
2500base-t).
