Subject: DT: net: davinci_emac: "phy-handle" property is actually optional
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=2c2dc1619e429c30356d76d29e93576ba031a80c;p=linux.git
DT: net: davinci_emac: "phy-handle" property is actually optional
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.
