  • ac96b737c   spi: spi-mpc52xx-psc: Remove deprecated create_singlethread_workqueue ... Browse Code »

    The workqueue "workqueue" has a single work item(&mps->work)
    doesn't require ordering. Also, it is not being used on a memory reclaim
    path. Hence, the singlethreaded workqueue has been replaced with the use
    of system_wq.

    System workqueues have been able to handle high level of concurrency
    for a long time now and hence it's not required to have a singlethreaded
    workqueue just to gain concurrency. Unlike a dedicated per-cpu workqueue
    created with create_singlethread_workqueue(), system_wq allows multiple
    work items to overlap executions even on the same CPU; however, a
    per-cpu workqueue doesn't have any CPU locality or global ordering
    guarantee unless the target CPU is explicitly specified and thus the
    increase of local concurrency shouldn't make any difference.

    Work item has been flushed in mpc52xx_psc_spi_of_remove() to ensure that
    nothing is pending while disconnecting the driver.

  • f6bd03a74   spi: Don't break user-visible strings to multiple source lines in drivers ... Browse Code »

    User-visible strings are more difficult to grep from sources if they are
    separated to multiple source lines. This is worse than over 80 columns long
    line code style violation.

    Fix this by making those to single-line strings or by breaking them between
    variables.

    While at there, convert if (printk_ratelimit()) dev_warn() to use
    dev_warn_ratelimited in spi-pxa2xx.c.

  • 24b5a82cf   spi: use platform_{get,set}_drvdata() ... Browse Code »

    Use the wrapper functions for getting and setting the driver data using
    platform_device instead of using dev_{get,set}_drvdata() with &pdev->dev,
    so we can directly pass a struct platform_device.

  • fd4a319bc   spi: Remove HOTPLUG section attributes ... Browse Code »

    CONFIG_HOTPLUG is going away as an option. As result the __dev*
    markings will be going away.

    Remove use of __devinit, __devexit_p, __devinitdata, __devinitconst,
    and __devexit.

    Bill Pemberton has done most of the legwork on this series. I've used
    his script to purge the attributes from the drivers/gpio tree.

  • c8c87c656   spi/mpc52xx-psc: Avoid access to freed memory in device remove function ... Browse Code »

    The call to spi_unregister_master() in the device remove function frees device
    memory, and with it any device local data. However, device local data is still
    accessed after the call to spi_unregister_master().

    Acquire a reference to the SPI master device and release it after cleanup is
    complete to solve the problem.

  • 940ab8896   drivercore: Add helper macro for platform_driver boilerplate ... Browse Code »

    For simple modules that contain a single platform_driver without any
    additional setup code then ends up being a block of duplicated
    boilerplate. This patch adds a new macro, module_platform_driver(),
    which replaces the module_init()/module_exit() registrations with
    template functions.

  • ca632f556   spi: reorganize drivers ... Browse Code »

    Sort the SPI makefile and enforce the naming convention spi_*.c for
    spi drivers.

    This change also rolls the contents of atmel_spi.h into the .c file
    since there is only one user of that particular include file.

    v2: - Use 'spi-' prefix instead of 'spi_' to match what seems to be
    be the predominant pattern for subsystem prefixes.
    - Clean up filenames in Kconfig and header comment blocks
