    net-next: dsa: add dsa support for Mediatek MT7530 switch · b8f126a8
    Sean Wang authored
    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.
