Ah, that is different. So the board is using it for RGMII to 1000Base-KX?
phy-mode is about the MAC-PHY link. So in this case RGMII.
There is no DT way to configure the PHY-Switch link. However, it sounds like you have the PHY strapped so it is doing 1000BaseX on the PHY-Switch link. So do you actually need to configure this?
You report you never see link up? So maybe the problem is actually in read_status? When in 1000BaseX mode, do you need to read the link status from some other register? The Marvell PHYs use a second page for 1000BaseX.
