    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.

  • f55f14752   ASoC: mxs-saif: Fix channel swap for 24-bit format ... Browse Code »

    Playing 24-bit format file leads to channel swap on mx28 and the reason is that
    the current driver performs one write/read to/from the SAIF_DATA register to
    trigger the transfer.

    This approach works fine for S16_LE case because SAIF_DATA is a 32-bit register
    and thus is capable of storing the 16-bit left and right channels, but for the
    S24_LE case it can only store one channel, so in order to not lose the FIFO sync
    an extra read/write is needed.

    Set an initial clock rate for the saif internal logic to work
    properly. This is important when working in EXTMASTER mode that
    uses the other saif's BITCLK&LRCLK but it still needs a basic
    clock which should be fast enough for the internal logic.

  • c2e1d9073   ASoC: mxs-saif: fix clock prepare and enable unbalance issue ... Browse Code »

    Currently we directly call a clock_enable in trigger function without
    a clk_prepare as pair first.
    This will cause system hang immediately when run capture because
    the clock was not prepared(playback does not hang because the clock was
    prepared already by get_mclk before), a warning message in clock framework
    may cause a deadlock to reclaim clock lock (see: pl011_console_write).

    Here we prepare clock first in hw_param, then enable it in trigger
    function to guarantee the balance.

  • 9883ab229   ASoC: dmaengine-pcm: Rename and deprecate snd_dmaengine_pcm_pointer ... Browse Code »

    Currently the sound dmaengine pcm helper functions implement the pcm_pointer
    callback by trying to count the number of elapsed periods. This is done by
    advancing the stream position in the dmaengine callback by one period.
    Unfortunately there is no guarantee that the callback will be called for each
    elapsed period. It may be possible that under high system load it is only called
    once for multiple elapsed periods. This patch renames the current implementation
    and documents its shortcomings and that it should not be used anymore in new
    drivers.

    The next patch will introduce a new snd_dmaengine_pcm_pointer which will be
    implemented based on querying the current stream position from the dma device.

  • bc92657a1   ASoC: make snd_soc_dai_link more symmetrical ... Browse Code »

    Prior to this patch, the CPU side of a DAI link was specified using a
    single name. Often, this was the result of calling dev_name() on the
    device providing the DAI, but in the case of a CPU DAI driver that
    provided multiple DAIs, it needed to mix together both the device name
    and some device-relative name, in order to form a single globally unique
    name.

    However, the CODEC side of the DAI link was specified using separate
    fields for device (name or OF node) and device-relative DAI name.

    This patch allows the CPU side of a DAI link to be specified in the same
    way as the CODEC side, separating concepts of device and device-relative
    DAI name.

    I believe this will be important in multi-codec and/or dynamic PCM
    scenarios, where a single CPU driver provides multiple DAIs, while also
    booting using device tree, with accompanying desire not to hard-code the
    CPU side device's name into the original .cpu_dai_name field.

    Ideally, both the CPU DAI and CODEC DAI loops in soc_bind_dai_link()
    would now be identical. However, two things prevent that at present:

    1) The need to save rtd->codec for the CODEC side, which means we have
    to search for the CODEC explicitly, and not just the CODEC side DAI.

    2) Since we know the CODEC side DAI is part of a codec, and not just
    a standalone DAI, it's slightly more efficient to convert .codec_name/
    .codec_of_node into a codec first, and then compare each DAI's .codec
    field, since this avoids strcmp() on each DAI's CODEC's name within
    the loop.

    However, the two loops are essentially semantically equivalent.

  • 2e341ca68   Merge tag 'sound-3.5' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound ... Browse Code »

    Pull sound updates from Takashi Iwai:
    "This is the first big chunk for 3.5 merges of sound stuff.

    There are a few big changes in different areas. First off, the
    streaming logic of USB-audio endpoints has been largely rewritten for
    the better support of "implicit feedback". If anything about USB got
    broken, this change has to be checked.

    For HD-audio, the resume procedure was changed; instead of delaying
    the resume of the hardware until the first use, now waking up
    immediately at resume. This is for buggy BIOS.

    For ASoC, dynamic PCM support and the improved support for digital
    links between off-SoC devices are major framework changes.

    Some highlights are below:

    * HD-audio
    - Avoid accesses of invalid pin-control bits that may stall the codec
    - V-ref setup cleanups
    - Fix the races in power-saving code
    - Fix the races in codec cache hashes and connection lists
    - Split some common codes for BIOS auto-parser to hda_auto_parser.c
    - Changed the PM resume code to wake up immediately for buggy BIOS
    - Creative SoundCore3D support
    - Add Conexant CX20751/2/3/4 codec support

    * ASoC
    - Dynamic PCM support, allowing support for SoCs with internal
    routing through components with tight sequencing and formatting
    constraints within their internal paths or where there are multiple
    components connected with CPU managed DMA controllers inside the
    SoC.
    - Greatly improved support for direct digital links between off-SoC
    devices, providing a much simpler way of connecting things like
    digital basebands to CODECs.
    - Much more fine grained and robust locking, cleaning up some of the
    confusion that crept in with multi-component.
    - CPU support for nVidia Tegra 30 I2S and audio hub controllers and
    ST-Ericsson MSP I2S controolers
    - New CODEC drivers for Cirrus CS42L52, LAPIS Semiconductor ML26124,
    Texas Instruments LM49453.
    - Some regmap changes needed by the Tegra I2S driver.
    - mc13783 audio support.

    * Misc
    - Rewrite with module_pci_driver()
    - Xonar DGX support for snd-oxygen
    - Improvement of packet handling in snd-firewire driver
    - New USB-endpoint streaming logic
    - Enhanced M-audio FTU quirks and relevant cleanups
    - Increment the support of OSS devices to 256
    - snd-aloop accuracy improvement

    There are a few more pending changes for 3.5, but they will be sent
    slightly later as partly depending on the changes of DRM."

    Fix up conflicts in regmap (due to duplicate patches, with some further
    updates then having already come in from the regmap tree). Also some
    fairly trivial context conflicts in the imx and mcx soc drivers.

  • 6b35f924b   ASoC: mxs: Fix mxs-saif timeout ... Browse Code »

    On a mx28evk board the following errors happens on mxs-sgtl5000 probe:

    [ 0.660000] saif0_clk_set_rate: divider writing timeout
    [ 0.670000] mxs-sgtl5000: probe of mxs-sgtl5000.0 failed with error -110
    [ 0.670000] ALSA device list:
    [ 0.680000] No soundcards found.

    This timeout happens because clk_set_rate will result in writing to the DIV bits
    of register HW_CLKCTRL_SAIF0 with the saif clock gated (CLKGATE bit set to one).

    MX28 Reference states the following about CLKGATE:

    "The DIV field can change ONLY when this clock gate bit field is low."

    So call clk_prepare_enable prior to clk_set_rate to fix this problem.

    After this change the mxs-saif driver can be correctly probed and audio is functional.
