* ASoC: Enable ASoC register map dump for some regmap CODECsMark Brown2011-12-301-0/+8
| | | | | | | It's still useful to be able to poke around in the register map at runtime. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
* ASoC: Remove unused label from wm8994 probe()Mark Brown2011-12-291-1/+1

* ASoC: Remove WM8994 register cacheMark Brown2011-12-131-87/+0
| | | | | | | | | Now that the mfd is using the register map cache there's no need for the CODEC driver to do any register cache management or any funny dances to interact with the other drivers using the device so just remove the cache initialisation and volatility information.

* ASoC: Remove ASoC-specific WM8994 I/O codeMark Brown2011-12-131-51/+12
| | | | | | | Just go directly to the regmap API, saving code and making integration that bit more direct. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>

| * ASoC: Mark WM8994 ADC muxes as virtualMark Brown2011-12-021-6/+6
| | | | | | | | | | | | | | | | Since they don't actually have power bits but do have events associated with them it's important that we bootstrap their state properly which making them virtual does. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>

* | ASoC: Drop unused state parameter from CODEC suspend callbackLars-Peter Clausen2011-12-021-1/+1
| | | | | | | | | | | | | | | | | | | | The existence of this parameter is purely historical. None of the CODEC drivers uses it and we always pass in the same value anyway, so it should be safe to remove it.

* | ASoC: Convert WM8994 to devm_kzalloc()Mark Brown2011-12-011-7/+4
| | | | | | | | | | | | | | Still have a manual free in there for some realloc()ed memory as there's no devm version of that. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
* | ASoC: Add platform data for WM8958/WM1811 microphone detection ratesMark Brown2011-12-011-8/+4
| | | | | | | | | | | | | | | | Allow systems to override the default microphone detection rates using platform data in case the settings are not suitable (eg, due to an unusually noisy jack). Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
* | ASoC: Ensure we reconfigure WM8958 microphone detection on rate changesMark Brown2011-12-011-4/+2
| | | | | | | | | | | | | | | | We don't need to rerun DAPM if the clock source is the same but we do need to adjust the microphone detection rate in case we are moving from an audio to a non-audio rate. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
* | ASoC: Implement support for WM1811A jack detectionMark Brown2011-12-011-19/+245
| | | | | | | | | | | | | | | | | | | | | | The WM1811A features an advanced low power accessory detection subsystem which allows the device to be maintained in a very low power state while the system is idle without sacrificing any accessory detection features. Implement software support for this, automatically managing the power configuration of the device depending on the detected accessory. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
* | ASoC: Rename WM8994 detecting flag to mic_detectingMark Brown2011-12-011-6/+6
| | | | | | | | | | | | More specific and avoids confusion with a following change. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
* | ASoC: Allow more WM8958/WM1811 button levels with default handlerMark Brown2011-12-011-8/+34
| | | | | | | | | | | | | | | | The WM8958 and WM1811 support detecting a range of buttons. Allow the user to provide platform data enabling more of these levels without having to write a custom detection handler. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
* | ASoC: Tune down active mode detection rate for WM8958 mic detectionMark Brown2011-12-011-2/+2

* | ASoC: Put WM8958 and WM1811 MICBIAS into bypass mode when no audioMark Brown2011-11-291-1/+39
| | | | | | | | | | | | | | When we don't have any active audio we can put the microphone biases into bypass mode to save power at the expense of performance. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
* | ASoC: Ensure SYSCLK is enabled for WM8958 accessory detectionMark Brown2011-11-291-0/+3
| | | | | | | | | | | | | | | | Ensure SYSCLK is enabled while running accessory detection on WM8958. It is always required so there is no sense in requiring machine drivers to individually do this. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>

* | ASoC: Constify snd_soc_dai_ops structsLars-Peter Clausen2011-11-231-3/+3
|/ | | | | | | | | | | | | | | | | | | | | | | Commit 1ee46ebd("ASoC: Make the DAI ops constant in the DAI structure") introduced the possibility to have constant DAI ops structures, yet this is barley used in both existing drivers and also new drivers being submitted, although none of them modifies its DAI ops structure. The later is not surprising since existing drivers are often used as templates for new drivers. So this patch just constifies all existing snd_soc_dai_ops structs to eliminate the issue altogether. The patch was generated with the following coccinelle semantic patch: // <smpl> @@ identifier ops; @@ -struct snd_soc_dai_ops ops = +const struct snd_soc_dai_ops ops = { ... }; // </smpl> Signed-off-by: Lars-Peter Clausen <lars@metafoo.de> Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
* ASoC: Ensure we get an impedence reported for WM8958 jack detectMark Brown2011-11-041-11/+26
| | | | | | | | | Occasionally we may see an accessory reported before we have a stable impedance for the accessory. If this happens then reread the status in order to ensure that the handler can take the appropriate action for the status change. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>

| | | | | | | | | | | | | | | | | | | | Pull control is availalbe for WM8994 AIF2, generally disabled as part of the GPIO configuration in order to save power after system startup. As on newer devices in the series there is no GPIO functionality on these pins this will happen less naturally so have the driver disable the pulls as the AIF is probed.

| | | | | | | | | | | | | | | | | | | | | | On WM8994 class devices only the analogue portions of the CODEC require VMID so when running digital only paths we can leave VMID disabled. On some earlier devices the FLL uses VMID so we don't use DAPM reference counting alone, we maintain an internal reference count which is also enabled and disabled by the FLL startup.

| | | | | | | | | | | | | | | | | | | | | | | | The WM8994 and WM8958 series of devices have two MICBIAS supplies rather than one, the current widget actually manages the microphone detection control register bit (which is managed separately by the relevant API).
