    ASoC: Updates for v3.12

    - DAPM is now mandatory for CODEC drivers in order to avoid the repeated
    regressions in the special cases for non-DAPM CODECs and make it
    easier to integrate with other components on boards. All existing
    drivers have had some level of DAPM support added.
    - A lot of cleanups in DAPM plus support for maintaining controls in a
    specific state while a DAPM widget all contributed by Lars-Peter Clausen.
    - Core helpers for bitbanged AC'97 reset from Markus Pargmann.
    - New drivers and support for Analog Devices ADAU1702 and ADAU1401(a),
    Asahi Kasei Microdevices AK4554, Atmel AT91ASM9x5 and WM8904 based
    machines, Freescale S/PDIF and SSI AC'97, Renesas R-Car SoCs, Samsung
    Exynos5420 SoCs, Texas Instruments PCM1681 and PCM1792A and Wolfson
    Microelectronics WM8997.
    - Support for building drivers that can support it cross-platform for
    compile test.

  • 673c24e95   ASoC: omap: simplify platform_get_resource_byname/devm_ioremap_resource ... Browse Code »

    Remove unneeded error handling on the result of a call to
    platform_get_resource_byname when the value is passed to devm_ioremap_resource.

    In the case of omap-dmic.c, the error-handling code of
    devm_ioremap_resource is also corrected to include releasing the clock.

    A simplified version of the semantic patch that makes this change is as
    follows: (http://coccinelle.lip6.fr/)

    //
    @@
    expression pdev,res,e,e1;
    expression ret != 0;
    identifier l;
    @@

    res = platform_get_resource_byname(...);
    - if (res == NULL) { ... \(goto l;\|return ret;\) }
    e = devm_ioremap_resource(e1, res);
    //

  • bf7c6e6cc   ASoC: omap-hdmi-codec: make the driver common for other SoCs ... Browse Code »

    to support HDMI on CSR SiRFprimaII and atlasVI, we need one more HDMI pseudo
    codec, rather than add a new driver, we can make omap HDMI codec common for
    other SoCs as well. then the omap-hdmi codec becomes a generic HDMI pseudo-
    codec as HDMI audio features depend on HDMI specification not on SoCs.

  • 7c1c1d4a7   ASoC: dmaengine-pcm: Make requesting the DMA channel at PCM open optional ... Browse Code »

    Refactor the dmaengine PCM library to allow the DMA channel to be requested
    before opening a PCM substream. snd_dmaengine_pcm_open() now expects a DMA
    channel instead of a filter function and filter parameter as its parameters.
    snd_dmaengine_pcm_close() is updated to not release the DMA channel. This allows
    a dmaengine based PCM driver to request its channels before the substream is
    opened.

    The patch also introduces two new functions, snd_dmaengine_pcm_open_request_chan()
    and snd_dmaengine_pcm_close_release_chan(), which have the same signature and
    behaviour of the old snd_dmaengine_pcm_{open,close}() and internally use the new
    variants of these functions. All users of snd_dmaengine_pcm_{open,close}() are
    updated to use snd_dmaengine_pcm_open_request_chan() and
    snd_dmaengine_pcm_close_release_chan().

  • 340af748b   ASoC: omap-pcm: No need to wrap snd_dmaengine_pcm_close() ... Browse Code »

    If a PCM driver using the dmaengine PCM helper functions doesn't need to do
    anything special in its pcm_close callback, snd_dmaengine_pcm_close can be used
    directly for as the pcm_close callback and there is no need to wrap it in a
    custom function.

  • abe99370b   ASoC: omap: Call omap_mcbsp_set_threshold() from mcbsp hw_params ... Browse Code »

    The omap PCM driver provides a set_threshold callback which gets called by the
    PCM driver when either playback or capture is started. The only DAI driver which
    sets this callback is the mcbsp driver. This patch removes the callback from the
    PCM driver and moves the invocation of the omap_mcbsp_set_threshold() function
    to the mcbsp hw_params callback since this is the only place where the threshold
    size can change. Doing so allows us to use the default dmaengine PCM trigger
    callback in the omap PCM driver.

  • 81054b226   ASoC: omap-mcpdm: Fix for full duplex audio use case ... Browse Code »

    Due to HW limitation within OMAP McPDM IP uplink and downlink need to be
    started at the same time. This causes issues when we have two streams
    running, for example:
    arecord | aplay

    In this case the playback stream would have no channels enabled since at the
    capture start we are not aware that a playback is going to start.

    The workaround is to configure the other direction to stereo when the first
    stream is started. When the second stream is coming we check the new stream's
    number of channels against the pre-configured channels. If it does not match
    we stop and restart McPDM to update the configuration. This might result a
    small pop. If the coming stream is a match we do nothing in the McPDM driver.

    This workaround can handle most use cases without the need to restart McPDM.

    Convert all uses of devm_request_and_ioremap() to the newly introduced
    devm_ioremap_resource() which provides more consistent error handling.

    devm_ioremap_resource() provides its own error messages so all explicit
    error messages can be removed from the failure code paths.
