  • e4f8bb37e   ASoC: atmel: atmel_ssc_dai: move .suspend/.resume to component ... Browse Code »

    There is no big difference at implementation for .suspend/.resume
    between DAI driver and Component driver.
    But because some driver is using DAI version, thus ALSA SoC needs
    to keep supporting it, hence, framework becoming verbose.
    If we can switch all DAI driver .suspend/.resume to Component driver,
    we can remove verbose code from ALSA SoC.

    Driver is getting its private data via dai->dev.
    But dai->dev and component->dev are same dev, thus, we can convert
    these. For same reason, we can convert dai->active to
    component->active if necessary.

    This patch moves DAI driver .suspend/.resume to Component driver

  • 0dce49efc   ASoC: atmel_ssc_dai: Remove wrong spinlock usage ... Browse Code »

    A potential bug was reported in the email "[BUG] atmel_ssc_dai: a
    possible sleep-in-atomic bug in atmel_ssc_shutdown"[1]

    Indeed in the function atmel_ssc_shutdown() free_irq() was called in a
    critical section protected by spinlock.

    However this spinlock is only used in atmel_ssc_shutdown() and
    atmel_ssc_startup() functions. After further analysis, it occurred that
    the call to these function are already protected by mutex used on the
    calling functions.

    Then we can remove the spinlock which will fix this bug as a side
    effect. Thanks to this patch the following message disappears:

    "BUG: sleeping function called from invalid context at
    kernel/locking/mutex.c:909"

    Rework DAI format calculation in preparation for adding more formats
    later. As a side-effect this enables all CBM/CBS x CFM/CFS combinations
    for supported formats. (Note: the additional modes are not tested.)

    Note: this changes FSEDGE to POSITIVE for I2S CBM_CFS mode as the TXSYN
    interrupt is not used anyway.

  • b6d6c6e95   ASoC: atmel_ssc_dai: Allow more rates ... Browse Code »

    When the SSC acts as BCK master, use a ratnum rule to limit
    the rate instead of only doing the standard rates. When the SSC
    acts as BCK slave, allow any BCK frequency up to the SSC master
    clock, divided by either of 2, 3 or 6.

    Put a cap at 384kHz. Who's /ever/ going to need more than that?

    The divider of 2, 3 or 6 is selected based on the Serial Clock Ratio
    Considerations section from the SSC documentation:

    The Transmitter and the Receiver can be programmed to operate
    with the clock signals provided on either the TK or RK pins.
    This allows the SSC to support many slave-mode data transfers.
    In this case, the maximum clock speed allowed on the RK pin is:
    - Peripheral clock divided by 2 if Receiver Frame Synchro is input
    - Peripheral clock divided by 3 if Receiver Frame Synchro is output
    In addition, the maximum clock speed allowed on the TK pin is:
    - Peripheral clock divided by 6 if Transmit Frame Synchro is input
    - Peripheral clock divided by 2 if Transmit Frame Synchro is output

  • eb58960e9   ASoC: atmel_ssc_dai: Match the CMR divider only in full duplex. ... Browse Code »

    The CMR divider register is shared by playback and capture. The SSC driver
    therefore tries to enforce rules so that the needed register content do
    not conflict during simultaneous playback/capture. However, the
    implementation also prevents changing the register content in
    half-duplex scenarios, which is needed when using the OSS API.

    Thus, only lock the divider if there is a stream in the other direction.

    Fixes the below program to not fail with the atmel ssc dai in master mode.

    int
    main(void)
    {
    int fd;
    int format;
    int channels;
    int speed;

    if ((fd = open("/dev/dsp", O_WRONLY, 0)) == -1) {
    perror("open");
    return 1;
    }
    format = AFMT_S16_LE;
    if (ioctl(fd, SNDCTL_DSP_SETFMT, &format) == -1) {
    perror("SNDCTL_DSP_SETFMT");
    return 1;
    }
    channels = 2;
    if (ioctl(fd, SNDCTL_DSP_CHANNELS, &channels) == -1) {
    perror("SNDCTL_DSP_CHANNELS");
    return 1;
    }
    speed = 22025;
    if (ioctl(fd, SNDCTL_DSP_SPEED, &speed) == -1) {
    perror("SNDCTL_DSP_SPEED");
    return 1;
    }
    return 0;

    When SSC work as master, it will generate the frame sync signal.
    On old SoCs, it only supports frame sync length less or equal to
    16bits, on newer SoCs, it supports frame sync length extension,
    which can support frame size larger than 16 bits.
    So, add this to make it supports playback 24/32 bits audio clips.
