  • 8d9d7f018   net: phy: realtek: Use the dummy stubs for MMD register access for rtl8211b ... Browse Code »

    [ Upstream commit 0231b1a074c672f8c00da00a57144072890d816b ]

    The Ethernet on mpc8315erdb is broken since commit b6b5e8a69118
    ("gianfar: Disable EEE autoneg by default"). The reason is that
    even though the rtl8211b doesn't support the MMD extended registers
    access, it does return some random values if we trying to access
    the MMD register via indirect method. This makes it seem that the
    EEE is supported by this phy device. And the subsequent writing to
    the MMD registers does cause the phy malfunction. So use the dummy
    stubs for the MMD register access to fix this issue.

    Fixes: b6b5e8a69118 ("gianfar: Disable EEE autoneg by default")

  • e3230494b   net: phy: realtek: fix enabling of the TX-delay for RTL8211F ... Browse Code »

    The old logic always enabled the TX-delay when the phy-mode was set to
    PHY_INTERFACE_MODE_RGMII. There are dedicated phy-modes which tell the
    PHY driver to enable the RX and/or TX delays:
    - PHY_INTERFACE_MODE_RGMII should disable the RX and TX delay in the
    PHY (if required, the MAC should add the delays in this case)
    - PHY_INTERFACE_MODE_RGMII_ID should enable RX and TX delay in the PHY
    - PHY_INTERFACE_MODE_RGMII_TXID should enable the TX delay in the PHY
    - PHY_INTERFACE_MODE_RGMII_RXID should enable the RX delay in the PHY
    (currently not supported by RTL8211F)

    With this patch we enable the TX delay for PHY_INTERFACE_MODE_RGMII_ID
    and PHY_INTERFACE_MODE_RGMII_TXID.
    Additionally we now explicity disable the TX-delay, which seems to be
    enabled automatically after a hard-reset of the PHY (by triggering it's
    reset pin) to get a consistent state (as defined by the phy-mode).

    This fixes a compatibility problem with some SoCs where the TX-delay was
    also added by the MAC. With the TX-delay being applied twice the TX
    clock was off and TX traffic was broken or very slow (

  • d5bf9071e   phylib: Support registering a bunch of drivers ... Browse Code »

    If registering of one of them fails, all already registered drivers
    of this module will be unregistered.

    Use the new register/unregister functions in all drivers
    registering more than one driver.

    amd.c, realtek.c: Simplify: directly return registration result.

    Tested with broadcom.c
    All others compile-tested.

  • cf93c9458   net/phy: fix many "defined but unused" warnings ... Browse Code »

    MODULE_DEVICE_TABLE only expands to something if it's compiled
    for a module. So when building-in support for the phys, the
    mdio_device_id tables are unused. Marking them with __maybe_unused
    fixes the following warnings:
