The first two patches prepare the sun8i-emac driver to deal with the EMAC as integrated into the H616 SoC. This IP block is compatible with the A64 version, but the current driver prevents us from using that: - The EPHY syscon register needs to have a bit cleared to select the external PHY. On the A64 it is cleared on reset, but we should not rely on that. The Linux driver does so as well. Fixed in patch 1/3. - The pinmux setting is tied to the compatible string, but the H616 requires a different value. Fixed in patch 2/3.
The final patch enables Ethernet support for the OrangePi Zero 2 board, which now works without further ado.
Cheers, Andre
