-Subject: [PATCH 30/57] net-next: dsa: add dsa support for Mediatek MT7530
- switch
-
-MT7530 is a 7-ports Gigabit Ethernet Switch that could be found on
-Mediatek router platforms such as MT7623A or MT7623N platform which
-includes 7-port Gigabit Ethernet MAC and 5-port Gigabit Ethernet PHY.
-Among these ports, The port from 0 to 4 are the user ports connecting
-with the remote devices while the port 5 and 6 are the CPU ports
-connecting into Mediatek Ethernet GMAC.
-
-For port 6, it can communicate with the CPU via Mediatek Ethernet GMAC
-through either the TRGMII or RGMII which could be controlled by phy-mode
-in the dt-bindings to specify which mode is preferred to use. And for
-port 5, only RGMII can be specified. However, currently, only port 6 is
-being supported in this DSA driver.
-
-The driver is made with the reference to qca8k and other existing DSA
-driver. The most of the essential callbacks of the DSA are already
-support in the driver, including tag insert for user port distinguishing,
-port control, bridge offloading, STP setup and ethtool operation to allow
-DSA to model each user port into a standalone netdevice as the other DSA
-driver had done.
