   12 description:
   13   If the QCA8K switch is connect to an SoC's external mdio-bus, each subnode
   14   describing a port needs to have a valid phandle referencing the internal PHY
   15   it is connected to. This is because there is no N:N mapping of port and PHY
   16   ID. To declare the internal mdio-bus configuration, declare an MDIO node in
   17   the switch node and declare the phandle for the port, referencing the internal
   18   PHY it is connected to. In this config, an internal mdio-bus is registered and
   19   the MDIO master is used for communication. Mixed external and internal
   20   mdio-bus configurations are not supported by the hardware.

   54       Set LEDs to open-drain mode. This requires the qca,ignore-power-on-sel to
   55       be set, otherwise the driver will fail at probe. This is required if the
   56       OEM does not use pin strapping to set this mode and prefers to set it
   57       using SW regs. The pin strappings related to LED open-drain mode are
   58       B68 on the QCA832x and B49 on the QCA833x.

   64                  If this is not present, the legacy mapping is used and the
   65                  internal mdio access is used.
   66                  With the legacy mapping the reg corresponding to the internal
   67                  mdio is the switch reg with an offset of -1.

  103               or greater, a warning will be displayed. When the CPU port is set to
  104               SGMII on the QCA8337, it is advised to set this unless a communication
  105               issue is observed.
