2008-12-09ASoC: Add platform registration APIMark Brown1-0/+38
ASoC v2 allows platform drivers to instantiate independantly of the overall ASoC card. This API allows drivers to notify the core when they are registered. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
2008-12-09ASoC: Add DAI registration APIMark Brown1-0/+83
Add API calls to register and unregister DAIs with the core. Currently these APIs are ineffective. Since multiple DAIs for a given device are a common case bulk variants are provided. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
2008-12-09ASoC: Add card registration APIMark Brown1-0/+62
ASoC v2 allows cards, codecs and platforms to instantiate separately, with the overall ASoC device only being instantiated once all the required components have registered. As part of backporting Liam's work introduce an initial version of the card registration functions. At present these do nothing active and are internal only, they will be exposed to machine drivers after further backporting. Adding this now allows the datastructures used for dynamic card instantiation to be built up gradually. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
2008-12-03ASoC: Remove platform device from DAI suspend and resume operationsMark Brown1-4/+4
None of the DAIs use it except s3c2412-i2s which only uses it for dev_() printouts. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
2008-12-03ASoC: Remove device from platform suspend and resume operationsMark Brown1-2/+2
None of the platforms are actually using the SoC device so remove it (only atmel actually has a suspend method). Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
2008-12-03ASoC: Push debugfs files out of the snd_soc_device structureMark Brown1-32/+41
This is in preparation for the removal of struct snd_soc_device. The pop time configuration should really be a property of the card not the codec but since DAPM currently uses the codec rather than the card using the codec is fine for now.

2008-12-02ASoC: Push platform registration down into the cardMark Brown1-19/+25
As part of the deprecation of snd_soc_device push the registration of the platform down into the card structure. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
2008-12-02ASoC: Push workqueue data into snd_soc_cardMark Brown1-13/+20
ASoC v2 does not use the struct snd_soc_device at runtime, using struct snd_soc_card as the root of the card. Begin removing data from snd_soc_device by pushing the workqueue data into snd_soc_card, using a backpointer to the snd_soc_device to keep things going for the time being.

2008-12-01ASoC: Rename snd_soc_register_card() to snd_soc_init_card()Mark Brown1-3/+3
Currently ASoC card initialisation is completed by a function called snd_soc_register_card(). As part of the work to allow independant registration of cards, codecs and machines in ASoC v2 a new function of the same name has been added so rename the existing function to facilitate the merge of v2.

2008-11-24ASoC: Lower priority of resume work loggingMark Brown1-4/+4
Now that the ASoC resume has been punted to a workqueue for a release cycle without attracting bug reports it should be safe to make the log messages associated with it debug level, reducing noise and kernel size in production configurations. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
2008-11-24ASoC: Remove DAI type informationMark Brown1-23/+8
DAI type information is only ever used within ASoC in order to special case AC97 and for diagnostic purposes. Since modern CPUs and codecs support multi function DAIs which can be configured for several modes it is more trouble than it's worth to maintain anything other than a flag identifying AC97 DAIs so remove the type field and replace it with an ac97_control flag. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
2008-11-21ASoC: Merge snd_soc_ops into snd_soc_dai_opsMark Brown1-37/+37
Liam Girdwood's ASoC v2 work avoids having two different ops structures for DAIs by merging the members of struct snd_soc_ops into struct snd_soc_dai_ops, allowing per DAI configuration for everything. Backport this change. This paves the way for future work allowing any combination of DAIs to be connected rather than having fixed purpose CODEC and CPU DAIs and only allowing CODEC<->CPU interconnections. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
2008-11-21ASoC: Rename snd_soc_card to snd_soc_machineMark Brown1-45/+45
One of the issues with the ASoC v1 API which has been addressed in the ASoC v2 work that Liam Girdwood has done is that the ALSA card provided by ASoC is distributed around the ASoC structures. For example, machine wide data such as the struct snd_card are maintained as part of the CODEC data structure, preventing the use of multiple codecs. This has been addressed by refactoring the data structures so that all the data for the ALSA card is contained in a single structure snd_soc_card which replaces the existing snd_soc_machine and snd_soc_device. Begin the process of backporting this by renaming struct snd_soc_machine to struct snd_soc_card, better reflecting its function and bringing it closer to standard ALSA terminology.

2008-11-05ASoC: Remove core version numberMark Brown1-1/+0
Rather than try to remember to keep the core version number updated (which hasn't been happening) just remove it. It was much more useful when ASoC was out of tree. Signed-off-by: Mark brown <broonie@opensource.wolfsonmicro.com>

2008-10-30ASoC: Fix handling of DAPM suspend workMark Brown1-32/+23
Since we can query the playback stream power state directly we do not need to infer if it is powered up from the timer being scheduled.

2008-10-30ALSA: ASoC: Fix mono controls after conversion to support full int masksMark Brown1-1/+1
When ASoC was converted to support full int width masks SOC_SINGLE_VALUE() omitted the assignment of rshift, causing the control operatins to report some mono controls as stereo. This happened to work some of the time due to a confusion between shift and min in snd_soc_info_volsw().

2008-07-29ALSA: ASoC: Rename mask to max to reflect usageJon Smirl1-10/+10
Most of the ASoC controls refer to the maximum value that can be set for a control as mask but there is no actual requirement for all bits to be set at the highest possible value making the name mask misleading.

Some codecs have unusual features in their register maps such as very large registers representing arrays of coefficients.

2008-05-19[ALSA] ASoC: Clarify API for bias configurationMark Brown1-12/+13
Currently the ASoC core configures the bias levels in the system using a callback on codecs and machines called 'dapm_event', passing it PCI style power levels as SNDRV_CTL_POWER_ constants. This is more obscure than it needs to be and has caused confusion to driver authors, especially given that DAPM is also performing power management. Address this by renaming the callback function to 'set_bias_level' and using constants explicitly representing the off, standby, pre-on and on states which DAPM transitions through. Also unexport the API for setting bias level: there are currently no in-tree users of this API other than the core itself and it is likely that the core would need to be extended to cater for any users.

This patch fixes a bug whereby AC97 bus device data was being clobbered when AC97 codecs using the generic ac97_codec.c driver were being registered. Codecs that didn't use the generic driver were unaffected (e.g. WM9712, WM9713).
