Subject: [PATCH net-next 0/3] net: enetc: add port MDIO support for both i.MX94 and i.MX95

For the external PHY devices, NETC provide external MDIO interface to
manage them. ENETC can use a set of MDIO registers provided by EMDIO to
access its PHY, which is a method currently supported by the driver. It
also can use its own set of MDIO registers to access its PHY, but the
premise is that its corresponding LaBCR[MDIO_PHYAD_PRTAD] needs to be
set correctly, which indicates its PHY address.

Similar to the external MDIO registers, each ENETC has a set of internal
MDIO registers to access its on-die PHY (PCS), so internal MDIO support
is also added.

  net: enetc: set external MDIO PHY address for i.MX95 ENETC

  net: enetc: set external MDIO PHY address for i.MX94 ENETC
  net: enetc: add port MDIO support for ENETC v4
