[PATCH] DT: net: davinci_emac: "phy-handle" property is actually optional

[Sergei Shtylyov]

Though described as required, the "phy-handle" property for the DaVinci EMAC
binding is actually optional, as the driver will happily function without it,
assuming 100/FULL link; the property is not specified  either in the example
device node,  or in the actual EMAC device nodes for DA850 and AM3517 device
trees.

The patch is against DaveM's 'net-next.git' repo.  Though being a fix, it does
not seem important enough for 'net.git' repo at this time. Not sure if it should
be considered for the stable kernels...
