  • a68660e0c   [ALSA] ASoC AC97 device reg bugfix ... Browse Code »

    This patch fixes a bug whereby AC97 bus device data was being clobbered
    when AC97 codecs using the generic ac97_codec.c driver were being
    registered. Codecs that didn't use the generic driver were unaffected
    (e.g. WM9712, WM9713).
    Changes:-
    o Add new AC97 codec class for custom (or need bus dev registration)
    AC97 codecs.
    o Only register/deregister this custom codec device with the AC97 bus.
    The generic AC97 driver already does this for generic codec devices.
    This may be related to bug #3038 :-

  • 1c433fbda   [ALSA] soc - 0.13 ASoC headers ... Browse Code »

    This patch updates the API's to include the new DAI configuration and
    clocking architecture.
    Changes:-
    o Removed DAI automatic matching and capabilities structure (struct
    snd_soc_dai_mode) and macros.
    o Added DAI operations for codec and CPU interfaces.
    o Removed config_sysclk() function and struct snd_soc_clock_info. No
    longer needed as clocking is now configured manually in the machine
    drivers. Also removed other clocking data from structures.
    o Updated version to 0.13
    o Added shift to SOC_SINGLE_EXT kcontrol macro.

  • 4484bb2e9   [ALSA] Fix the soc code after dhowells workqueue changes. ... Browse Code »

    From: Andrew Morton
    I converted the workqueues to per-device while I was there. It seems
    strange to create a new kernel thread (on each CPU!) and to then only
    have a single global work to ever be queued upon it.
    Plus without this, I'd have to use the _NAR stuff, gawd help me.
    Does that workqueue really need to be per-cpu?
    Does that workqueue really need to exist? Why not use keventd?

  • a71a468a5   [ALSA] ASoC: Add support for BCLK based on (Rate * Chn * Word Size) ... Browse Code »

    This patch adds support for the DAI BCLK to be generated by multiplying
    Rate * Channels * Word Size (RCW).
    This now gives 3 options for BCLK clocking and synchronisation :-
    1. BCLK = Rate * x
    2. BCLK = MCLK / x
    3. BCLK = Rate * Chn * Word Size. (New)
    Changes:-
    o Add support for RCW generation of BCLK
    o Update Documentation to include RCW.
    o Update DAI documentation for label = value DAI modes.
    o Add RCW support to wm8731, wm8750 and pxa2xx-i2s drivers.
