  • 9810489ca   net: phy: add XFI, USXGMII types to is_10g_interface() helper ... Browse Code »

    The helper is used to reset PHYs on connect and it determines the clause
    to use (C22/C45) based on interface type. This fixes 'PHY reset timed out'
    warnings in console for USXGMII/XFI PHYs.

  • e2ffeaa16   phy: Include NC-SI in phy setup ... Browse Code »

    Add NC-SI to the usual phy handling. This makes two notable changes:
    - Somewhat similar to a fixed phy, phy_connect() will create an NC-SI
    phy if CONFIG_PHY_NCSI is defined.
    - An early return is added to phy_read() and phy_write() to handle a
    case like the NC-SI phy which does not define a bus.

  • f641a8ac9   phy: Add support for the NC-SI protocol ... Browse Code »

    This introduces support for the NC-SI protocol, modelled as a phy driver
    for other ethernet drivers to consume.

    NC-SI (Network Controller Sideband Interface) is a protocol to manage a
    sideband connection to a proper network interface, for example a BMC
    (Baseboard Management Controller) sharing the NIC of the host system.
    Probing and configuration occurs by communicating with the "remote" NIC
    via NC-SI control frames (Ethernet header 0x88f8).

    This implementation is roughly based on the upstream Linux
    implementation[0], with a reduced feature set and an emphasis on getting
    a link up as fast as possible rather than probing the full possible
    topology of the bus.
    The current phy model relies on the network being "up", sending NC-SI
    command frames via net_send_packet() and receiving them from the
    net_loop() loop (added in a following patch).

    The ncsi-pkt.h header[1] is copied from the Linux kernel for consistent
    field definitions.

    This patch adds support for gmiitorgmii converter.
    This converter sits between the MAC and the external phy
    MAC GMII2RGMII RGMII_PHY.
    The ethernet driver probes this bridge and this bridge driver
    probes real phy driver and invokes the real phy functionalities
    as requested. This bridge just needs to be configured based on
    real phy negotiated speed and duplex.

  • 4f6746dc7   net: phy: Add generic helpers to access MMD PHY registers ... Browse Code »

    Two new helper functions (phy_read_mmd() and phy_write_mmd()) are added
    to allow access to the MMD PHY registers.

    The MMD PHY registers can be accessed by several means:

    1. Using two new MMD access function hooks in the PHY driver. These
    functions can be implemented when the PHY driver does not support the
    standard IEEE Compatible clause 45 access mechanism described in clause
    22 or if the PHY uses its own non-standard access mechanism.

    2. Direct access for C45 PHYs and C22 PHYs when accessing the reachable
    DEVADs.

    3. The standard clause 45 access extensions to the MMD registers through
    the indirection registers (clause 22) in all the other cases.

  • eef0b8a93   net: phy: add ofnode node to struct phy_device ... Browse Code »
    1

    Now the UCLASS_ETH device "node" field is owerwritten by some network drivers in
    case of Ethernet PHYs which are linked to UCLASS_ETH device using
    "phy-handle" DT property and when Ethernet PHY driver needs to read some
    additional information from DT. In such cases following happens (in
    general):

    - network drivers
    priv->phydev = phy_connect(priv->bus, priv->phyaddr, dev,
    priv->interface);
    phy_of_handle > 0)
    dev_set_of_offset(priv->phydev->dev, priv->phy_of_handle);
    dev->node is overwritten by phy-handle DT node

    - PHY driver in .config() callback
    int node = dev_of_offset(dev);
    node
    const void *fdt = gd->fdt_blob;

    if (fdtdec_get_bool(fdt, node, "property"))
    ...

    As result, UCLASS_ETH device can't be used any more for DT accessing.

    This patch adds additional ofnode node field to struct phy_device which can
    be set explicitly by network drivers and used by PHY drivers, so
    overwriting can be avoided. Also add helper function phy_get_ofnode()
    which will check and return phy_device->node or dev_ofnode(phydev->dev) for
    backward compatibility with existing drivers.

  • 83d290c56   SPDX: Convert all of our single license tags to Linux Kernel style ... Browse Code »
    56

    When U-Boot started using SPDX tags we were among the early adopters and
    there weren't a lot of other examples to borrow from. So we picked the
    area of the file that usually had a full license text and replaced it
    with an appropriate SPDX-License-Identifier: entry. Since then, the
    Linux Kernel has adopted SPDX tags and they place it as the very first
    line in a file (except where shebangs are used, then it's second line)
    and with slightly different comment styles than us.

    In part due to community overlap, in part due to better tag visibility
    and in part for other minor reasons, switch over to that style.

    This commit changes all instances where we have a single declared
    license in the tag as both the before and after are identical in tag
    contents. There's also a few places where I found we did not have a tag
    and have introduced one.

    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.
