[PATCH v3 0/7] Fixes for the NXP LS1028A-QDS boards

[Vladimir Oltean]

This series fixes through patches 1, 2 and 6 networking issues seen on
the LS1028A-QDS boards:
- Traffic through the RGMII port enetc-1 does not work
- The switch ports are not probed
- RGMII fixed-link connections do not work

Patches 3 and 4 are dependencies for patch 6, as follows:
- Forcing the MAC speed to equal the RGMII PHY requires having a PHY
  unconditionally in the enetc driver
- Having a PHY unconditionally requires updating the device tree to
  declare fixed PHYs for the internal enetc ports

Finally, patches 5 and 7 are cleanup changes, which disables the DSA
master port enetc-2 on LS1028A-QDS boards where the switch is not
enabled, and propagate an error code.

Changes in v2:
Reword commit message of patch 6.

Changes in v3:
Update driver copyright as part of corporate requirements.
Add patch 7.

Vladimir Oltean (7):
  arm: dts: ls1028a: enable the switch CPU port for the LS1028A-QDS
  arm: dts: ls1028a: enable internal RGMII delays for the LS1028A-QDS
    AR8035 PHY
  arm: dts: ls1028a: declare the fixed-link speeds for the internal
    ENETC ports
  arm: dts: ls1028a: disable enetc-2 by default
  net: enetc: require a PHY device when probing
  net: enetc: force the RGMII MAC speed/duplex instead of using in-band
    signaling
  net: enetc: propagate the return code from phy_startup() to
    eth_ops::start
