Commit e34d65696d2e ("stmmac: create of compatible mdio bus for stmmac driver") broke DW GMAC functionality on ARC AXS10x boards: That's what happens on eth0 up: --------------------------->8------------------------ | libphy: PHY stmmac-0:ffffffff not found | eth0: Could not attach to PHY | stmmac_open: Cannot attach to PHY (error: -19) --------------------------->8------------------------ Simplest solution is to add PHY description in board's .dts. And so we do here. Signed-off-by: Alexey Brodkin Cc: Rob Herring Cc: Phil Reid Cc: David S.
