  • a390e85cf   wl12xx: move common init code from bus modules to main ... Browse Code »

    Move all common parts from sdio.c and spi.c to main.c, since they now
    can be handled as part of the platform driver.

  • 341b7cde6   wl12xx: Handle platforms without level trigger interrupts ... Browse Code »

    Some platforms are incapable of triggering on level interrupts. Add a
    platform quirks member in the platform data structure, as well as an
    edge interrupt quirk which can be set on such platforms.

    When the interrupt is requested with IRQF_TRIGGER_RISING, IRQF_ONESHOT
    cannot be used, as we might miss interrupts that occur after the FW
    status is cleared and before the threaded interrupt handler exits.

    Moreover, when IRQF_ONESHOT is not set, iterating more than once in the
    threaded interrupt handler introduces a few race conditions between this
    handler and the hardirq handler. Currently this is worked around by
    limiting the loop to one iteration only. This workaround has an impact
    on performance. To remove to this restriction, the race conditions will
    need to be addressed.

  • d29633b40   wl12xx: Clean up and fix the 128x boot sequence ... Browse Code »

    Clean up the boot sequence code & fix the following issues:
    1. Always read the registers' values and set the relevant bits instead of
    zeroing all other bits
    2. Handle cases where wl1271_top_reg_read returns an error
    3. Verify that the HW can detect the selected clock source
    4. Remove 128x PG10 initialization code
    5. Configure the MCS PLL to work in HP mode

  • 15cea9930   wl1271: make ref_clock configurable by board ... Browse Code »

    The wl1271 device is using a reference clock that may change
    between board to board.

    Make the ref_clock parameter configurable by board settings
    instead of having a hard coded value in the sources.

  • 61ee7007a   wl12xx: add platform data passing support ... Browse Code »

    Add a simple mechanism to pass platform data to the
    SDIO instances of wl12xx.

    This way there is no confusion over who owns the 'embedded data',
    typechecking is preserved, and no possibility for the wrong driver to
    pick up the data.

    Originally proposed by Russell King.

    Move wl12xx.h outside of the spi-specific location,
    so it can be shared with both spi and sdio solutions.

    Update all users of spi/wl12xx.h accordingly
