  • 8880edba0   net: add MDIO_MUX DM class ... Browse Code »

    Adds a class for MDIO MUXes, which control access to a series of
    downstream child MDIOs.
    MDIO MUX drivers are required to implement a select function used to switch
    between child buses.
    MUX children are registered as MDIO buses and they can be used just like
    regular MDIOs.

  • 9215bb1f3   miiphy: Add function to retrieve MDIO bus list head ... Browse Code »

    In upcoming freescale board LX2160AQDS, the MDIO bus is muxed.
    i.e. same MDIO bus can be routed to eight different slots depending
    on mux register settings.

    To support this mdio mux behavior, we add each MDIO bus mux as a
    separate MDIO bus.

    Now, various phy devices can be attached to each of these slots(mux).
    The information about these devices is passed to OS via device tree.

    To do the fdt fixups related to MDIO bus, its necessary that MDIO bus
    list is accessed.Therefore, add a function to retrieve the list head.

  • 4549e789c   SPDX: Convert all of our multiple license tags to Linux Kernel style ... Browse Code »

    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 multiple licenses (in
    these cases, dual license) declared in the SPDX-License-Identifier tag.
    In this case we change from listing "LICENSE-A LICENSE-B" or "LICENSE-A
    or LICENSE-B" or "(LICENSE-A OR LICENSE-B)" to "LICENSE-A OR LICENSE-B"
    as per the Linux Kernel style document. Note that parenthesis are
    allowed so when they were used before we continue to use them.

  • 79e2a6a04   common: miiphyutil: Add helper function for mdio bus name ... Browse Code »

    The most of ethernet drivers are using this mdio registration sequence.
    strcpy(priv->bus->name, "emac");
    mdio_register(priv->bus);
    Where driver can be used only with one MDIO bus because only unique
    name should be used.

    Other drivers are using unique device name for MDIO registration to
    support multiple instances.
    snprintf(priv->bus->name, sizeof(bus->name), "%s", name);

    With DM dev->seq is used more even in logs
    (like random MAC address generation:
    printf("\nWarning: %s (eth%d) using random MAC address - %pM\n",
    dev->name, dev->seq, pdata->enetaddr);
    )
    where eth%d prefix is used.

    Simplify driver code to register mdio device with dev->seq number
    to simplify mdio registration and reduce code duplication across
    all drivers. With DM_SEQ_ALIAS enabled dev->seq reflects alias setting.

  • 1b387ef55   SPDX: fix IBM-pibs license identifier ... Browse Code »

    The SPDX License List version 1.19 now contains an official entry for
    the IBM-pibs license. However, instead of our suggestion "ibm-pibs",
    the SPDX License List uses "IBM-pibs", with the following rationale:
    "The reason being that all other SPDX License List short identifiers
    tend towards using capital letters unless spelling a word. I'd prefer
    to be consistent to this end".

    Change the license IDs to use the official name.

    This commit adapts the files that were derived from PIBS (PowerPC
    Initialization and Boot Software) codeto using SPDX License
    Identifiers.

    So far, SPDX has not assigned an official License ID for the PIBS
    license yet, so this should be considered preliminary.

    Note that the following files contained incorrect license information:

    arch/powerpc/cpu/ppc4xx/4xx_uart.c
    arch/powerpc/cpu/ppc4xx/start.S
    arch/powerpc/include/asm/ppc440.h

    These files included, in addition to the GPL-2.0 / ibm-pibs dual
    license as inherited from PIBS, a GPL-2.0+ license header which was
    obviously incorrect. This has been removed.

  • f6add132f   net/miiphy/serial: drop duplicate "NAMESIZE" define ... Browse Code »

    A few subsystems are using the same define "NAMESIZE". This has been
    working so far because they define it to the same number. However, I
    want to change the size of eth_device's NAMESIZE, so rather than tweak
    the define names, simply drop references to it. Almost no one does,
    and the handful that do can easily be changed to a sizeof().

    It causes a lot of "incompatible pointer type" warnings for a large
    number of Ethernet drivers, which are not really worth fixing
    especially as this patch was only supposed to help the old,
    deprecated miiphy API. Instead of adding more efforts to a lost case
    we rather revert it.

  • 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.

    git://git.kernel.org/pub/scm/linux/kernel/git/davem/net-next-2.6

  • 4ba31ab33   Rewrite the miiphybb (Bit-banged MII bus driver) in order to support an arbitrar… ... Browse Code »

    …y number of mii buses.

    This feature is useful when your board uses different mii buses for different
    phys and all (or a part) of these buses are implemented via bit-banging mode.

    The driver requires that the following macros should be defined into the board
    configuration file:

    CONFIG_BITBANGMII - Enable the miiphybb driver
    CONFIG_BITBANGMII_MULTI - Enable the multi bus support

    If the CONFIG_BITBANGMII_MULTI is not defined, the board's config file needs
    to define at least the following macros:

    MII_INIT - Generic code to enable the MII bus (optional)
    MDIO_DECLARE - Declaration needed to access to the MDIO pin (optional)
    MDIO_ACTIVE - Activate the MDIO pin as out pin
    MDIO_TRISTATE - Activate the MDIO pin as input/tristate pin
    MDIO_READ - Read the MDIO pin
    MDIO(v) - Write v on the MDIO pin
    MDC_DECLARE - Declaration needed to access to the MDC pin (optional)
    MDC(v) - Write v on the MDC pin

    The previous macros make the driver compatible with the previous version
    (that didn't support the multi-bus).

    When the CONFIG_BITBANGMII_MULTI is also defined, the board code needs to fill
    the bb_miiphy_buses[] array with a record for each required bus and declare
    the bb_miiphy_buses_num variable with the number of mii buses.
    The record (struct bb_miiphy_bus) has the following fields/callbacks (see
    miiphy.h for details):

    char name[] - The symbolic name that must be equal to the MII bus
    registered name
    int (*init)() - Initialization function called at startup time (just
    before the Ethernet initialization)
    int (*mdio_active)() - Activate the MDIO pin as output
    int (*mdio_tristate)() - Activate the MDIO pin as input/tristate pin
    int (*set_mdio)() - Write the MDIO pin
    int (*get_mdio)() - Read the MDIO pin
    int (*set_mdc)() - Write the MDC pin
    int (*delay)() - Delay function
    void *priv - Private data used by board specific code

    The board code will look like:

    struct bb_miiphy_bus bb_miiphy_buses[] = {
    { .name = miibus#1, .init = b1_init, .mdio_active = b1_mdio_active, ... },
    { .name = miibus#2, .init = b2_init, .mdio_active = b2_mdio_active, ... },
    ...
    int bb_miiphy_buses_num = sizeof(bb_miiphy_buses) /
    sizeof(bb_miiphy_buses[0]);

    It was brought to our attention that U-Boot contains code derived from the
    IBM OpenBIOS source code originally provided with some of the older PowerPC
    4xx development boards. As a result, the original license of this code has
    been carried in the various files for a number of years in the U-Boot project.

    IBM is dual-licensing the IBM code contributions already present in U-Boot
    under either the terms of the GNU General Public License version 2, or the
    original code license already present.
