[PATCH RFT net-next 07/10] arm64: dts: allwinner: a527: cubie-a5e: Enable second Ethernet port

[Chen-Yu Tsai]

From: Chen-Yu Tsai <wens at csie.org>

On the Radxa Cubie A5E board, the second Ethernet controller, aka the
GMAC200, is connected to a second external Maxio MAE0621A PHY. The PHY
uses an external 25MHz crystal, and has the SoC's PJ16 pin connected to
its reset pin.

Enable the second Ethernet port. Also fix up the label for the existing
external PHY connected to the first Ethernet port.
