Subject: [PATCH net-next v1 0/4] enetc: Add mdio bus driver for the PCIe MDIO endpoint

Second patch just registers the PCIe endpoint device containing
the MDIO registers as a standalone MDIO bus driver, to allow
an alternative way to control the MDIO bus.  The same code used
by the ENETC ports (eth controllers) to manage MDIO via local
registers applies and is reused.

Bindings are provided for the new MDIO node, similarly to ENETC
port nodes bindings.

Last patch enables the ENETC port 1 and its RGMII PHY on the
LS1028A QDS board, where the MDIO muxing configuration relies
on the MDIO support provided in the first patch.

Claudiu Manoil (4):
  enetc: Clean up local mdio bus allocation
  enetc: Add mdio bus driver for the PCIe MDIO endpoint
  dt-bindings: net: fsl: enetc: Add bindings for the central MDIO PCIe
    endpoint
  arm64: dts: fsl: ls1028a: Enable eth port1 on the ls1028a QDS board
