Each child node of an MDIO node is scanned as a PHY when calling of_mdiobus_register() givint the following result: [ 18.175379] mdio_bus stmmac-0: /soc/ethernet@1c30000/mdio/mdio-mux has invalid PHY address [ 18.175408] mdio_bus stmmac-0: scan phy mdio-mux at address 0 [ 18.175450] mdio_bus stmmac-0: scan phy mdio-mux at address 1 [...] [ 18.176420] mdio_bus stmmac-0: scan phy mdio-mux at address 30 [ 18.176452] mdio_bus stmmac-0: scan phy mdio-mux at address 31 Since mdio-mux nodes are not PHY, this patch a way to to not scan them.This can be dropped now, right?
Yes and it is dropped in my two last serie. Forgot to said it in changelog
