Introduce documentation for a device tree binding for the Intel Platform Controller Hub (PCH) GigaBit Ethernet (GBE) device. Although this is a PCIe device & thus largely auto-detectable, this binding will be used to provide the driver with the PHY reset GPIO. Signed-off-by: Paul Burton <paul.burton@mips.com> Cc: David S.
