Hello,
This series adds support for CPSW3G MAC port 2 with the SK-Ethernet-DC01
Add-On daughtercard. Also, the missing alias for CPSW3G MAC Port 1 is
added to the am62a7-sk board file in order to allow kernel to fetch MAC
address populated by U-Boot for CPSW3G MAC Port 1.
This series is based on linux-next tagged next-20240424.
Link to v1:
https://lore.kernel.org/r/20230424111945.3865240-1-s-vadapalli@ti.com/
Changes from v1 to v2:
- Since support for device tree overlays for am62a7-sk is already enabled
by commit "635ed9715194", it is removed from this series.
