    Add a minimalistic Broadcom BCM53xx (roboswitch) switch driver similar
    to the Marvell MV88E617x. This takes care of configuring the minimum
    amount out of the switch hardware such that each user visible port
    (configurable) and the CPU port can forward packets between each other
    while preserving isolation with other ports.

    This is useful for e.g: the Lamobo R1 board featuring a Broadcom
    BCM53125 switch.

  • d397f7c45   net: phy: micrel: Separate KSZ9000 drivers from KSZ8000 drivers ... Browse Code »
    12

    The KS8721BL and KSZ9021 PHYs are software-incompatible, yet they
    share the same ID. Drivers for bothe PHYs cannot safely coexist, so
    the solution was to use #ifdefs to select between the two drivers.

    As a result KSZ9031, which has a unique ID, is now caught in the
    crossfire. Unless CONFIG_PHY_MICREL_KSZ9031 is defined, the KSZ9031
    will not function properly, as some essential configuration code is
    ifdef'd-out.

    To prevent such situations, move the KSZ9000 drivers to a separate
    file, and place them under a separate Kconfig option. While it is
    possible to enable both KSZ8000 and KSZ9000 drivers at the same time,
    the assumption is that it is highly unlikely for a system to contain
    both a KSZ8000 and a KSZ9000 PHY, and that only one of the drivers
    will be enabled at any given time.

  • db40c1aa1   drivers/net/phy: add fixed-phy / fixed-link support ... Browse Code »
    1

    This patch adds support for having a "fixed-link" to some other MAC
    (like some embedded switch-device).

    For this purpose we introduce a new phy-driver, called "Fixed PHY".

    Fixed PHY works only with CONFIG_DM_ETH enabled, since the fixed-link is
    described with a subnode below ethernet interface.

    Most ethernet drivers (unfortunately not all are following same scheme
    for searching/attaching phys) are calling "phy_connect(...)" for getting
    a phy-device.
    At this point we link in, we search here for a subnode called "fixed-
    link", once found we start phy_device_create(...) with the special phy-
    id PHY_FIXED_ID (0xa5a55a5a).

    During init the "Fixed PHY" driver has registered with this id and now
    gets probed, during probe we get all the details about fixed-link out of
    dts, later on the phy reports this values.

    Finally, put a phy_interface field in struct eth_pdata since this is an
    important part of the platform data for Ethernet.

    - Cortina PHY has non-standard offset of PHY ID registers, thus

  • 9082eeac5   phylib: Add a bunch of PHY drivers from tsec ... Browse Code »

    The tsec driver had a bunch of PHY drivers already written. This
    converts them all into PHY Lib drivers, and serves as the first
    set of PHY drivers for PHY Lib.

    While doing that, cleaned up a number of magic numbers (though
    not all of them, as PHY vendors like to keep their numbers as
    magical as possible). Also, noticed that almost all of the
    vitesse/cicada PHYs had the same config/parse/startup functions,
    so those have been collapsed into one.

  • 5f184715e   Create PHY Lib for U-Boot ... Browse Code »

    Extends the mii_dev structure to participate in a full-blown MDIO and
    PHY driver scheme. The mii_dev structure and miiphy calls are modified
    in such a way to allow the original mii command and miiphy
    infrastructure to work as before, but also to support a new set of APIs
    which allow (among other things) sharing of PHY driver code and 10G support

    The mii command will continue to support normal PHY management functions
    (Clause 22 of 802.3), but will not be changed to support 10G
    (Clause 45).

    The basic design is similar to PHY Lib from Linux, but simplified for
    U-Boot's network and driver infrastructure.

    We now have MDIO drivers and PHY drivers

    An MDIO driver provides:
    read
    write
    reset

    A PHY driver provides:
    (optionally): probe
    config - initial setup, starting of auto-negotiation
    startup - waiting for AN, and reading link state
    shutdown - any cleanup needed

    The ethernet drivers interact with the PHY Lib using these functions:
    phy_connect()
    phy_config()
    phy_startup()
    phy_shutdown()

    Each PHY driver can be configured separately, or all at once using
    config_phylib_all_drivers.h (added in the patch which adds the drivers)

    We also provide generic drivers for Clause 22 (10/100/1000), and
    Clause 45 (10G) PHYs.

    We also implement phy_reset(), and call it in phy_connect(). Because
    phy_reset() is essentially the same as miiphy_reset, but:
    a) must support 10G PHYs, and
    b) should use the phylib primitives,

    we implement miiphy_reset, using phy_reset(), but only when
    CONFIG_PHYLIB is set. Otherwise, we just use the old version. In this
    way, we save on compile size, even if we don't manage to save code size.

    Pulled ethtool.h and mdio.h from:
    git://git.kernel.org/pub/scm/linux/kernel/git/davem/net-next-2.6
    782d640afd15af7a1faf01cfe566ca4ac511319d
    With many, many deletions so as to enable compilation under u-boot
