    In preparation for unconditionally passing the
    struct tasklet_struct pointer to all tasklet
    callbacks, switch to using the new tasklet_setup()
    and from_tasklet() to pass the tasklet pointer explicitly.

  • e17be6e1b   dmaengine: Remove dev_err() usage after platform_get_irq() ... Browse Code »

    We don't need dev_err() messages when platform_get_irq() fails now that
    platform_get_irq() prints an error message itself when something goes
    wrong. Let's remove these prints with a simple semantic patch.

    //
    @@
    expression ret;
    struct platform_device *E;
    @@

    ret =
    (
    platform_get_irq(E, ...)
    |
    platform_get_irq_byname(E, ...)
    );

    if ( \( ret < 0 \| ret

    While we're here, remove braces on if statements that only have one
    statement (manually).

  • 750afb08c   cross-tree: phase out dma_zalloc_coherent() ... Browse Code »

    We already need to zero out memory for dma_alloc_coherent(), as such
    using dma_zalloc_coherent() is superflous. Phase it out.

    This change was generated with the following Coccinelle SmPL patch:

    @ replace_dma_zalloc_coherent @
    expression dev, size, data, handle, flags;

    -dma_zalloc_coherent(dev, size, handle, flags)

  • fd3c69bd1   dmaengine: xgene-dma: move unmap to before callback ... Browse Code »

    Completion callback should happen after dma_descriptor_unmap() has
    happened. This allow the cache invalidate to happen and ensure that
    the data accessed by the upper layer is in memory that was from DMA
    rather than stale data. On some architecture this is done by the
    hardware, however we should make the code consistent to not cause
    confusion.

    This is in preperation of moving to a callback that provides results to the
    callback for the transaction. The conversion will maintain current behavior
    and the driver must convert to new callback mechanism at a later time in
    order to receive results.

    Pull dmaengine updates from Vinod Koul:
    "This time we have aded a new capability for scatter-gathered memset
    using dmaengine APIs. This is supported in xdmac & hdmac drivers

    We have added support for reusing descriptors for examples like video
    buffers etc. Driver will follow

    The behaviour of descriptor ack has been clarified and documented

    New devices added are:
    - dma controller in sun[457]i SoCs
    - lpc18xx dmamux
    - ZTE ZX296702 dma controller
    - Analog Devices AXI-DMAC DMA controller
    - eDMA support for dma-crossbar
    - imx6sx support in imx-sdma driver
    - imx-sdma device to device support

    Other:
    - jz4780 fixes
    - ioatdma large refactor and cleanup for removal of ioat v1 and v2
    which is deprecated and fixes
    - ACPI support in X-Gene DMA engine driver
    - ipu irq fixes
    - mvxor fixes
    - minor fixes spread thru drivers"

    [ The Kconfig and Makefile entries got re-sorted alphabetically, and I
    handled the conflict with the new Intel integrated IDMA driver by
    slightly mis-sorting it on purpose: "IDMA64" got sorted after "IMX" in
    order to keep the Intel entries together. I think it might be a good
    idea to just rename the IDMA64 config entry to INTEL_IDMA64 to make
    the sorting be a true sort, not this mismash.

    Also, this merge disables the COMPILE_TEST for the sun4i DMA
    controller, because it does not compile cleanly at all. - Linus ]

  • 77a68e56a   dmaengine: Add an enum for the dmaengine alignment constraints ... Browse Code »

    Most drivers need to set constraints on the buffer alignment for async tx
    operations. However, even though it is documented, some drivers either use
    a defined constant that is not matching what the alignment variable expects
    (like DMA_BUSWIDTH_* constants) or fill the alignment in bytes instead of
    power of two.

    Add a new enum for these alignments that matches what the framework
    expects, and convert the drivers to it.
