+description: |
+  There are two versions of MT7530, standalone and in a multi-chip module.
+
+  MT7530 is a part of the multi-chip module in MT7620AN, MT7620DA, MT7620DAN,
+  MT7620NN, MT7621AT, MT7621DAT, MT7621ST and MT7623AI SoCs.
+
+  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.
+
+  There is only the standalone version of MT7531.
+
+  Port 5 on MT7530 has got various ways of configuration.
+
+  For standalone MT7530:
+
+    - Port 5 can be used as a CPU port.
+
+    - PHY 0 or 4 of the switch can be muxed to connect to the gmac of the SoC
+      which port 5 is wired to. Usually used for connecting the wan port
+      directly to the CPU to achieve 2 Gbps routing in total.
+
+      The driver looks up the reg on the ethernet-phy node which the phy-handle
+      property refers to on the gmac node to mux the specified phy.
+
+      The driver requires the gmac of the SoC to have "mediatek,eth-mac" as the
+      compatible string and the reg must be 1. So, for now, only gmac1 of an
+      MediaTek SoC can benefit this. Banana Pi BPI-R2 suits this.
+      Check out example 5 for a similar configuration.
+
+    - Port 5 can be wired to an external phy. Port 5 becomes a DSA slave.
+      Check out example 7 for a similar configuration.
+
+  For multi-chip module MT7530:
+
+    - Port 5 can be used as a CPU port.
+
+    - PHY 0 or 4 of the switch can be muxed to connect to gmac1 of the SoC.
+      Usually used for connecting the wan port directly to the CPU to achieve 2
+      Gbps routing in total.
+
+      The driver looks up the reg on the ethernet-phy node which the phy-handle
+      property refers to on the gmac node to mux the specified phy.
+
+      For the MT7621 SoCs, rgmii2 group must be claimed with rgmii2 function.
+      Check out example 5.
+
+    - In case of an external phy wired to gmac1 of the SoC, port 5 must not be
+      enabled.
+
+      In case of muxing PHY 0 or 4, the external phy must not be enabled.
+
+      For the MT7621 SoCs, rgmii2 group must be claimed with rgmii2 function.
+      Check out example 6.
+
+    - Port 5 can be muxed to an external phy. Port 5 becomes a DSA slave.
+      The external phy must be wired TX to TX to gmac1 of the SoC for this to
+      work. Ubiquiti EdgeRouter X SFP is wired this way.
+
+      Muxing PHY 0 or 4 won't work when the external phy is connected TX to TX.
+
+      For the MT7621 SoCs, rgmii2 group must be claimed with gpio function.
+      Check out example 7.
