  • c1b78d05b   [POWERPC] Generalize tsi108 PHY types ... Browse Code »

    Add a phy_type field to the tsi108 ethernet structures to indicate which PHY
    is used on a board. This is derived from the "compatible" property in the
    ethernet-phy node of the device tree. The default remains the MV88E PHY.

    Also, convert the setup code to use of_get_mac_address instead of hard coding
    a lookup for the "address" property in the ethernet node.

    Add tsi108/9 on chip Ethernet controller driver support.

    The driver code collects the feedback of previous posting form the mailing
    list and gives the update.

    MPC7448HPC2 platform in arch/powerpc uses tsi108 bridge.

    The following is a brief description of the Ethernet controller:

    The Tsi108/9 Ethernet Controller connects Switch Fabric to two independent
    Gigabit Ethernet ports,E0 and E1. It uses a single Management interface to
    manage the two physical connection devices (PHYs). Each Ethernet port has
    its own statistics monitor that tracks and reports key interface
    statistics. Each port supports a 256-entry hash table for address
    filtering. In addition, each port is bridged to the Switch Fabric through
    a 2-Kbyte transmit FIFO and a 4-Kbyte Receive FIFO.

    Each Ethernet port also has a pair of internal Ethernet DMA channels to
    support the transmit and receive data flows. The Ethernet DMA channels use
    descriptors set up in memory, the memory map of the device, and access via
    the Switch Fabric. The Ethernet Controller’s DMA arbiter handles
    arbitration for the Switch Fabric. The Controller also has a register bus
    interface for register accesses and status monitor control.

    The PMD (Physical Media Device) interface operates in MII, GMII, or TBI
    modes. The MII mode is used for connecting with 10 or 100 Mbit/s PMDs.
    The GMII and TBI modes are used to connect with Gigabit PMDs. Internal
    data flows to and from the Ethernet Controller through the Switch Fabric.
    Each

    Ethernet port uses its transmit and receive DMA channels to manage data
    flows through buffer descriptors that are predefined by the system (the
    descriptors can exist anywhere in the system memory map). These
    descriptors are data structures that point to buffers filled with data
    ready to transmit over Ethernet, or they point to empty buffers ready to
    receive data from Ethernet.
