Port 5 is muxed to GMAC5 and can interface to an external phy. - Port 5 becomes an extra switch port. - Only works on platform where external phy TX<->RX lines are swapped. - Like in the Ubiquiti ER-X-SFP. - 4. Port 5 is muxed to GMAC5 and interfaces with the 2nd GAMC as 2nd CPU port. - Currently a 2nd CPU port is not supported by DSA code. - - Depending on how the external PHY is wired: - 1. normal: The PHY can only connect to 2nd GMAC but not to the switch - 2. swapped: RGMII TX, RX are swapped; external phy interface with the switch as - a ethernet port. But can't interface to the 2nd GMAC. - - Based on the DT the port 5 mode is configured. - - Driver tries to lookup the phy-handle of the 2nd GMAC of the master device. - When phy-handle matches PHY of port 0 or 4 then port 5 set-up as mode 2. - phy-mode must be set, see also example 2 below! - * mt7621: phy-mode = "rgmii-txid"; - * mt7623: phy-mode = "rgmii"; + 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.

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.
