  There are two versions of MT7530, standalone and in a multi-chip module.

  There are three versions of MT7530, standalone, in a multi-chip module and

  built-into a SoC.



  MT7530 is a part of the multi-chip module in MT7620AN, MT7620DA, MT7620DAN,

  MT7620NN, MT7621AT, MT7621DAT, MT7621ST and MT7623AI SoCs.



  The MT7988 SoC comes with a built-in switch similar to MT7531 as well as four

  Gigabit Ethernet PHYs. The switch registers are directly mapped into the SoC's

  memory map rather than using MDIO. The switch got an internally connected 10G

  CPU port and 4 user ports connected to the built-in Gigabit Ethernet PHYs.



  MT7530 in MT7620AN, MT7620DA, MT7620DAN and MT7620NN SoCs has got 10/100 PHYs

  and the switch registers are directly mapped into SoC's memory map rather than

  using MDIO. The DSA driver currently doesn't support this.
