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:
|
||
|
||
- Port 5 can be used as a CPU port.
|
||
|
||
- PHY 0 or 4 of the switch can be muxed to gmac5 of the switch. Therefore,
|
||
the gmac of the SoC which is wired to port 5 can connect to the PHY.
|
||
This is 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 on the gmac node refers to, 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 a
|
||
MediaTek SoC can benefit this. Banana Pi BPI-R2 suits this.
|
||
|
||
For the MT7621 SoCs, rgmii2 group must be claimed with rgmii2 function.
|
||
|
||
Check out example 5.
|
||
|
||
- For the multi-chip module MT7530, 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 wired to an external phy. Port 5 becomes a DSA slave.
|
||
|
||
For the multi-chip module MT7530, 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.
|
||
|
||
For the multi-chip module MT7530, 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.
