[PATCH 0/2] sunxi: a523: enable Ethernet

[Andre Przywara]

The first of the two Ethernet controllers in the Allwinner A527/T527
SoCs is compatible to the IP used in the A64 SoC, which our MAC driver
already supports. Since the recent DT update brought us the DT
description of the network interface, enable the driver and thus
Ethernet functionality on the two boards that work.
Patch 1/2 fixes the function name for the RGMII pins in the pinctrl
driver, while patch 2/2 just enables building the sun8i-emac driver.

Please have a look and test!

Cheers,
Andre

[PATCH 1/2] pinctrl: sunxi: a523: change Ethernet pin function name

[Andre Przywara]

The name of the pin function was changed last minute in the DT, from
emac0 to gmac0.
Adjust the name we use in the pinctrl driver accordingly.

[PATCH 2/2] sunxi: a527: radxa/avaota: enable Ethernet

[Andre Przywara]

The first of the two Ethernet controllers in the Allwinner A527/T527 is
compatible to the MAC from the previous SoCs. Consequently the recent DT
update brought use the MAC node, using the A64 compatible string as the
fallback, which works out of the box.

Enable the sun8i-emac Ethernet driver in the defconfig for the Radxa and
the Avaota boards, so that kernels and other data can be loaded via
TFTP. Please note that only one of the Ethernet sockets will work, the
second MAC is not compatible, and needs a new U-Boot driver. The
X96QPro+ TV box unfortunately uses only this second EMAC, so Ethernet
cannot be used there at the moment.
