  • 89c66ee89   spi: spi-davinci: Fix direction in dma_map_single() ... Browse Code »

    Commit 048177ce3b3962852fd34a7e04938959271c7e70 (spi: spi-davinci:
    convert to DMA engine API) introduced a regression: dma_map_single()
    is called with direction DMA_FROM_DEVICE for rx and for tx.

  • 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.

  • 32310aaf5   spi/davinci: use request_threaded_irq() to fix deadlock ... Browse Code »

    With RT pre-empt patch applied to Linux kernel, the irq handler will be
    force converted to an irq thread. spi driver can get back to back messages
    from the slave device. In such cases, IRQ thread doesn't get a chance to
    run to read the slave data. Hence the irq handler must be run in hard irq
    context to read/write data from slave device. Otherwise, the kernel goes
    into a deadlock. This patch fixes this issue when PREEMPT_RT_FULL is
    enabled in the kernel. A dummy thread function is provided to satisfy the
    request_threaded_irq() API. Passing a NULL for function also causes the
    irq handler to be executed in the thread context.

  • 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.

  • b7e97d221   Merge branch 'next' of git://git.infradead.org/users/vkoul/slave-dma ... Browse Code »

    Pull slave-dmaengine updates from Vinod Koul:
    "This time we have Andy updates on dw_dmac which is attempting to make
    this IP block available as PCI and platform device though not fully
    complete this time.

    We also have TI EDMA moving the dma driver to use dmaengine APIs, also
    have a new driver for mmp-tdma, along with bunch of small updates.

    Now for your excitement the merge is little unusual here, while
    merging the auto merge on linux-next picks wrong choice for pl330
    (drivers/dma/pl330.c) and this causes build failure. The correct
    resolution is in linux-next. (DMA: PL330: Fix build error) I didn't
    back merge your tree this time as you are better than me so no point
    in doing that for me :)"

    Fixed the pl330 conflict as in linux-next, along with trivial header
    file conflicts due to changed includes.

    Platform data for device drivers should be defined in
    include/linux/platform_data/*.h, not in the architecture
    and platform specific directories.

    This moves such data out of the davinci include directories

  • 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
