|\ | | | | | | | | | | | | | | | | | | git://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound into for-next ASoC: Updates for v3.10 A few more bug fixes, the DAPM clock fix is actually a driver specific one since currently there's only one user of the clock support due to the problems relying on the clock API.

* | ASoC: wm8994: Support constraining the maximum number of channels clockedMark Brown2013-03-21
|/ | | | | | | | | | | | Some systems use the audio CODEC to clock a DAI with multiple data lines in parallel, meaning that bit clocks are only required for a smaller number of channels than data is sent for. In some cases providing the extra bit clocks can take the other devices on the audio bus out of spec. Support such systems by allowing a maximum number of channels to be specified.

| | | | | | | | | | | | | | | | | | If we've got jack detection support then check that the jack is still inserted when handling a mic IRQ in order to avoid transient reports caused by shorts during the removal process as the two interrupts race with each other.

| * ASoC: wm8994: Simplify button detection codeMark Brown2012-12-03
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently the WM8994 driver allows the WM8958 microphone detection code to be replaced in its entirety, providing a default implementation. This doesn't actually reflect the needs of users well. They generally wish to replace only the accessory identification parts of the algorithm (eg, using an external GPIO to provide the equivalent of the JACKDET support in the WM1811A). In preparation for supporting these users better refactor the existing code so that we have separate identification and button detection callbacks, selecting between them rather than using the mic_detecting flag in the existing callback. This also simplifies the code by introducing a more explicit state machine for the detecting and button states. In anticipation of future refactoring the callback is left in the signature for wm8958_mic_detect(), it will be removed at a later stage.

| * ASoC: wm8994: Stop mic detection whenever we detect an open circuitMark Brown2012-12-03
| | | | | | | | | | | | | | | | | | Jack detection will not do anything to help us detect a microphone when there is a fault in the cable and the debounce we have is enough to avoid getting an intermediate result so halt microphone detection when we detect that one is not present.

| * ASoC: wm8994: Lower AIFnCLK divisor when dropping to 32kHzMark Brown2012-11-22
| | | | | | | | | | | | | | | | | | When lowering SYSCLK to 50kHz for accessory detection also lower the AIFnCLK divisor to normalise the clocking configuration within the device. This will not disrupt audio as we cannot support active audio with such a low SYSCLK. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>

* | ASoC: wm_hubs: Allow configuration of MICBIAS power up delay via pdataMark Brown2012-08-22
| | | | | | | | | | | | | | | | | | Sometimes the analogue circuitry connected to the microphone needs some time to settle after power up.

* | ASoC: wm8994: Ensure we get a notification on startup for jackdetMark Brown2012-08-03
| | | | | | | | | | | | | | | | | | | | | | Since jackdet only reports deltas it won't generate an interrupt on startup when a jack is not present. This doesn't make a difference to userspace but does mean we don't generate a notification via the internal notifier chains. Fix that by scheduling a work to poll the chip after the clock is enabled. Use an extremely large timeout since there's no urgency and we don't want to report a false negative. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
