  • Bcmdhd wifi driver default build as module, now default build in
    this wifi driver. To support this build in feature, this patch
    add flag ENABLE_INSMOD_NO_FW_LOAD, and use extern function
    sdio_reset_comm() as instead.

  • Some major fixes delivered by Broadcom.
    1. Initialize nd_config parameter of cfg80211_wowlan to NULL
    2. Avoid using hardcoded dummy channel number while creating p2p interface
    3. Avoid creation of multiple instance of wl_event_handler thread.

  • For MX7D LPSR mode, the controller will lost power and got the
    configuration state lost after system resume back.
    So we need to set pinctrl state again and re-start chip to do
    re-configuration after resume.

    For wakeup case, we also need re-configure the chip in case the state
    got lost. For interface is not up before suspend case, we don't need
    re-configure as it will be configured by user later by interface up.

  • In .mdio_bus_phy_may_suspend(), there check netdev is NULL to judge to set
    phy to suspend status.

    netdev is NULL has three cases:
    - phy is not found
    - phy is found, match to general phy driver
    - phy is found, match to specifical phy driver

    Case 1: phy is not found, cannot communicate by MDIO bus.
    Case 2: phy is found:
    if phy dev driver probe/bind err, netdev is not __open__ status,
    mdio bus is unregistered.
    if phy is detached, phy had entered suspended status.
    Case 3: phy is found, phy is detached, phy had entered suspended status.

    So, in here, it shouldn't set phy to suspend by calling mdio bus.

    In i.MX6UL evk/arm2 board, if down the ethx interface and do suspend/resume,
    system will hang. Because after ethx down all clocks are gated off, for general
    phy driver, unbind the phy device, for specifical phy driver, no unbind the
    device, and the original driver call mdio bus to set phy to suspend during
    system suspend, so system will hang since there have mdio register access.
    The patch can fix it.

  • bcmdhd can't support removing host during suspend and
    driver crash when detect card after resume due to no response
    to CMD7.
    It looks bcmdhd has a special requirement to enumerate card
    by itself which is incompatible with current MMC core.
    So implement post-cd feature to allow driver to detect card
    as it wants, then we add back non-removable capability
    to avoid MMC core to redetect card after resume.

  • During normal suspend process, disable all irqs to avoid the late
    TXF interrupt comming after clocks disabled that accessing registers
    cause system hang.

  • Current we can meet timeout issue when setting a small bitrate
    like 10000 as follows:
    root@imx6qdlsolo:~# ip link set can0 up type can bitrate 10000
    A link change request failed with some changes committed already.
    Interface can0 may have been left with an inconsistent configuration,
    please check.
    RTNETLINK answers: Connection timed out

    It is caused by calling of flexcan_chip_unfreeze() timeout.

    Originally the code is using usleep_range(10, 20) for unfreeze operation,
    but the patch (8badd65 can: flexcan: avoid calling usleep_range from
    interrupt context) changed it into udelay(10) which is only a half delay
    of before, there're also some other delay changes.

    After only changed unfreeze delay back to udelay(20), the issue is gone.
    So other timeout values are kept the same as 8badd65 changed.

  • Avoid to access the null interface before update tx status.

    This patch workaround to fix the panic when the p2p connection
    disconnect in the p2p stress test. The interface will be
    released during the disconnect process.

    Fixed coding style issue by Aisheng.

  • Current driver will meet the following warning on MX6SL platform which does
    not support ADMA.
    It is caused by the driver is using fixed scatter gather DMA not matter whether
    the host supports or not. Then the host without ADMA capability will warning
    if found the DMA sg_count is non-1.
    Change the driver a bit to avoid multi DMA scatter list if found the
    host->max_segs is only 1 to fix the issue.

  • Pull back sdpcm_hdrlen length from old skb as new skb here
    is passed to postprocessing.
    This is a generic fix. We must have it regardless of host is
    non scatter-gather or scatter gather capable.

  • As part of starting up IBSS, CFG80211 driver needs BSS information to be
    plumbed into it. Hence in DHD we call cfg80211_infrom_bss() and it needs whole
    frame consist of IEs contained in beacon frame. But FW was passing frame buffer
    with some extra bytes preceded and when same is plumbed into CFG80211 it was not
    able to decode the frame and it ignores the frame as result we get such warnings.
    Using latest FW delivered by Broadcom to fix the issue.

    As well as wl_cfg80211.c changes are essential. This change is actually fix certain
    warnings seen when moving between IBSS and BSS network mode.
    Changes must be done in wl_cfg80211_change_virtual_iface() which you can find at
    wl_cfg80211.c and this file is not specific wl tool.
