1. What if we just don't specific a phy address with a reg property which would specify to auto probe it and find the phy as illustrated below?Ethernet_MAC: ether...@81000000 { #address-cells = <1>; #size-cells = <1>; phy-handle = <&phy0>; mdio { #address-cells = <1>; #size-cells = <0>; phy0: p...@7 { } ; } ; 2. Or a special value (-1 or something not 0 - 31) in the phy address that specifies to auto probe as illustrated below. phy0: p...@7 { reg = <-1>; } ;I don't like abusing the reg property in this way. I wonder if a new empty property would be a better way to indicate this. Maybe "phy-probe-address;"? It would also be important to specify in the binding that only one phy node is allowed when phy-probe-address is used. Also, without a known reg the 'p...@7' name is inaccurate. Drop the @7. Scott, Andy: any thoughts?
I'm not fond of the -1. I'd prefer the explicit phy-probe-address property, though I don't mind too much using the absence of reg.
