  • 6d7f68a1e   ASoC: add support for Amstrad E3 (Delta) machine ... Browse Code »

    This patch adds machine support for Amstrad E3 (Delta) videophone to ASoC.

    Created and tested against linux-2.6.31-rc3.
    Applies and works with linux-omap-2.6 commit
    7c5cb7862d32cb344be7831d466535d5255e35ac as well.

    Depends on:
    1) latest version of the CX20442 codec driver that exposes v253_ops
    structure[1],
    2) patch 2/3 form this series: TTY: Add definition of a new line
    discipline required by Amstrad E3 (Delta) ASoC driver[2].

    CPU DAI parameters best matching the codec DAI has been selected out
    empirically for best user experience.

    Board specific audio function control (with related DAPM widgets) has been
    modeled after empirically discovered codec capabilities.

    Unlike other ASoC machine drivers, this one makes use of a codec provided line
    discipline that is required for talking to a modem chip that can control the
    codec behavoiur. As the line discipline operations must call board specific
    bits as well, the machine driver registers its own line discipline ops, not
    the codec provided, and then calls those codec provided from inside its own
    callbacks.
    If some kind of a glue, like a bus over a tty, exsited that could help in
    runtime detection of a modem (bus adapter) over a more generic line discipline
    (bus driver)[3], the line discipline code could be probably designed in a
    more generic way.

    In order to work at all, this driver requires a working McBSP1. On OMAP1510
    based machines (not sure if other OMAP1 variants as well), where McBSP1 is a
    DSP public peripheral, that means the kernel must provide basic DSP support,
    ie. omap_dsp_init(), in order to power up the DSP. This used to be included in
    linux-omap-2.6 tree up to commit 2512fd29db4eb09e82d182596304c7aaf76d2c5c.
    Without that, the driver would not work, ie. not shift in/out any bits over
    the CPU DAI[4]. This limitation is not board, but CPU specific, and may apply
    to other code that makes use of McBSP1/McBSP3 on affected machines. I provide
    an extra patch (4/3) as a temporary solution.

    To work correctly in playback mode, this driver requires my prevoiusly
    submitted patch that corrects pcm pointer calculation for OMAP1510 based
    machines[5] (already included in linux-2.6.31-rc3).

    To support codec controls, this driver requires my previously submitted patch
    that adds support for modem found on Amstrad Delta[6].

  • df205936d   ASoC: Zoom2: Add machine driver for Zoom2 board ... Browse Code »

    Add support for Zoom2 board. Zoom2 machine driver
    connects both codec DAIs (audio and voice) to omap3
    McBSP ports in the following way:

    HiFi McBSP2
    Voice McBSP3

    The zoom2 driver has the following DAPM widgets:
    * Ext Mic: MAINMIC, SUBMIC (with bias)
    * Ext Spk: HFL, HFR
    * Headset Stereophone: HSOL, HSOR
    * Headset Mic: HSMIC (with bias)
    * Aux In: AUXL, AUXR

  • d304c6ef6   ASoC: OMAP: Select OMAP pin multiplexing when using Nokia N810 ASoC drivers ... Browse Code »

    N810 bootloader muxes I2S pins for OMAP2420 EAC block while N810 ASoC
    drivers are using McBSP block so the kernel have to change configuration
    runtime.

    Author has not seen problems using kernel pin multiplexing on N810 but very
    many times unworking audio after forgotten to enable it and spending
    15 minutes each time to figure it out again...

    This change makes it easier for other users as well. If problems arise, then
    they are better to find and fix in OMAP pin multiplexing framework.
