[PATCH v3 0/2] rockchip: Enable Ethernet controller on Radxa E20C

[Jonas Karlman <jonas@kwiboo.se>]

The Rockchip RK3528 has two Ethernet controllers, one 100/10 MAC to be
used with the integrated PHY and a second 1000/100/10 MAC to be used
with an external Ethernet PHY.

This series add device tree nodes for the Ethernet controllers found in
RK3528 and enable the LAN interface on Radxa E20C.

This include a gmac0 node for the 100/10 MAC and its related integrated
PHY node that only have recived limited testing. I have no board that
expose an Ethernet port for the gmac0 and the integrated PHY. However,
the PHY can be identified on addr 0x2 as 0044.1400 and in vendor kernel
this relate to the Rockchip RK630 PHY. A proper PHY driver will be
needed to support any real use of gmac0.

Changes in v3:
- Rebase on top of latest mmind/for-next

Changes in v2:
- Split from the "Add GMAC support for RK3528" driver series [1]
- Add ethernet-phy@2 for the integrated PHY
- Rebase on top of the "Support I2C controllers in RK3528" series [2]
