Lothar Felten 3c2abf5019 sunxi: R40: add gigabit ethernet devicetree node
Add a device tree node for the Allwinner R40/V40 GMAC gigabit
ethernet interface.
The R40 SoC does not use the syscon register for GMAC settings.
The gigabit ethernet interface can only be routed to a fixed set of
pins.
Updated to match the Linux kernel's device tree.
