[PATCH v3 0/2] arm64: dts: socfpga: enable ethernet support for Agilex5

[PATCH v3 0/2] arm64: dts: socfpga: enable ethernet support for Agilex5

[Matthew Gerlach]

This patch set enables ethernet support for the Agilex5 family of SOCFPGAs,
and specifically enables gmac2 on the Agilex5 SOCFPGA Premium Development
Kit. Patches 1 and 4 from v2 have been merged; so they are dropped from this
version. The remaining two patches are unchanged from v2.

Link to v2:
https://lore.kernel.org/lkml/20250724154052.205706-1-matthew.gerlach@altera.com/T/#m3e3d9774dbdb34d646b53c04c46ec49d32254544
 
Patch 1 defines the base gmac nodes it the Agilex5 DTSI.

Patch 2 enables gmac2 on the Agilex5 SOCFPGA Premium Development Kit.

[PATCH v3 1/2] arm64: dts: Agilex5 Add gmac nodes to DTSI for Agilex5

[Matthew Gerlach]

From: Mun Yew Tham <mun.yew.tham@altera.com>

Add the base device tree nodes for gmac0, gmac1, and gmac2 to the DTSI
for the Agilex5 SOCFPGA.  Agilex5 has three Ethernet controllers based on
Synopsys DWC XGMAC IP version 2.10.

[PATCH v3 2/2] arm64: dts: socfpga: agilex5: enable gmac2 on the Agilex5 dev kit

[Matthew Gerlach]

Enable gmac2 on the Agilex5 SOCFGPA Development Kit. The MAC is connected
to a RGMII PHY on a daughter card. There are no RGMII clock delays
implemented the on PCB.

v3:
 - No change from v2.

v2:
 - change phy-mode to "rgmii-id"
 - add newline before inner device tree nodes
