[PATCH 0/2] rockchip: Fix ethernet on Radxa ROCK Pi E v1.21

[Jonas Karlman]

Ethernet on a Radxa ROCK Pi E v1.21 with a RTL8211F ethernet PHY
currently fails with the following message:

  Could not get PHY for ethernet at ff540000: addr -1

This happens because the ethernet PHY is never reset before a phy-id is
read back from the MDIO bus.

This series fixes this issue by calling eth_phy_set_mdio_bus() from the
designware ethernet driver to issue a PHY reset before the phy_connect()
call.

With the driver change and DM_ETH_PHY and PHY_REALTEK enabled the PHY
can be identified and etherent works:

  => mdio list
  ethernet at ff540000:
  1 - RealTek RTL8211F <--> ethernet at ff540000

This was tested with and without the DM_MDIO option enabled. Decided to
leave it disabled in this series.
