That's weird. AFAICT, the net part has hit Linus's tree.

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?

AFAIK, the pinmux is for the external pad Martin The internal phy does not use those pads. > > > Martin

AFAICT, the net part has hit Linus's tree. Ah, that's the key ingredient. I was testing with a v5.1 baseline (not linus/master) along with all my queued up changes. I just pulled in linus/master to test this series, and indeed, everything works, and I don't need my config fragment either. Thanks for clarifying.
