2013-08-06ASoC: wm8994: Fix class W controlsMark Brown1-1/+1
Commit 6e0650 (ASoC: wm8994: Use SOC_SINGLE_EXT() instead of open-coding it) went too far and converted a DAPM control to use SOC_SINGLE_EXT() which crashes. Revert that portion of the patch. Signed-off-by: Mark Brown <broonie@linaro.org>
2013-07-29ASoC: dapm: Add a helper to get the CODEC for DAPM kcontrolLars-Peter Clausen1-3/+1
We use the same 3 lines to get the CODEC for a kcontrol in a quite a few places. This patch puts them into a common helper function. Having this encapsulated in a helper function will also make it more easier to eventually change the data layout of the kcontrol's private data.

2013-07-19ASoC: wm8994: Use power efficient workqueueMark Brown1-9/+14
The accessory detect debounce work is not performance sensitive so let the scheduler run it wherever is most efficient rather than in a per CPU workqueue by using the system power efficient workqueue. Signed-off-by: Mark Brown <broonie@linaro.org> Acked-by: Viresh Kumar <viresh.kumar@linaro.org>

2013-07-15ASoC: wm8994: Move runtime PM init to platform device initMark Brown1-5/+5
As well as being better style this allows the device to idle when there is no audio card instantaited which is probably what we want. Signed-off-by: Mark Brown <broonie@linaro.org>

2013-06-01ASoC: wm8994: Allow debounce before MICDET identificationMark Brown1-2/+33
For systems which do not have a jack detection feature allow some debounce to be specified before we perform accessory identification, improving robustness without impacting button detection responsiveness. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>

2013-05-20ASoC: wm8994: Handle LRCLK inversion for WM8958 and WM1811AMark Brown1-0/+14
On WM8958 and WM1811A separate control of the LRCLK inversion bit is available for the DAC and ADC LRCLKs which for compatibility reasons is done in a new register bit. Since writes to each scheme have no effect on parts using the other just always write to both for simplicity.

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.
2013-04-30ASoC: wm8994: missing break in wm8994_aif3_hw_params()Dan Carpenter1-0/+1

2013-03-21ASoC: wm8994: Support constraining the maximum number of channels clockedMark Brown1-2/+11
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.

2012-12-03ASoC: wm8994: Check jack is inserted when handling mic IRQMark Brown1-0/+12
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. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
2012-12-03ASoC: wm8994: Support custom accessory identification for WM1811AMark Brown1-15/+21

2012-12-03ASoC: wm8994: Simplify button detection codeMark Brown1-50/+37
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.

2012-12-03ASoC: wm8994: Stop mic detection whenever we detect an open circuitMark Brown1-25/+31
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.

2012-11-22ASoC: wm8994: Lower AIFnCLK divisor when dropping to 32kHzMark Brown1-0/+12
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>

2012-10-24ASoC: wm8994: Only enable extra BCLK cycles when requiredMark Brown1-1/+17
Rather than always assuming the maximum possible BCLK rate will be required generate BCLKs for stereo if either one or two channels is enabled. In order to support this we also need to ensure that only the relevant channels are enabled. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>

2012-08-22ASoC: wm_hubs: Allow configuration of MICBIAS power up delay via pdataMark Brown1-0/+2
