I wonder if we're simply missing the pinctrl definitions in the ethmac node: pinctrl-0 = <ð_rmii_pins>; pinctrl-names = "default";
I don't know how the SoC works internally but I am assuming that the MDIO pins are routed to the "internal PHY" (within the chip). also we need the eth_rmii_pins anyways for the RXD/TXD pins which are connected to the physical Ethernet port on the board. bonus question: while writing this email I'm surprised to see that on GXL we don't use the rmii pins anywhere, why is Ethernet working fine there?
