* ASoC: DaVinci: pcm, fix underrun by using sramTroy Kisky2009-11-19
| | | | | | | | | | | | Fix underruns by using dma to copy 1st to sram in a ping/pong buffer style and then copying from the sram to the ASP. This also has the advantage of tolerating very long interrupt latency on dma completion.

* ASoC: DaVinci: McASP FIFO related updatesChaithrika U S2009-09-30
| | | | | | | | | | | The DMA params for McASP with FIFO has been updated so that it works for various FIFO levels. A member- 'fifo_level' has been added to the DMA params data structure. The fifo_level can be adjusted by the tx[rx]_numevt platform data. This is relevant only for DA8xx/OMAP-L1xx platforms. This implementation has been tested for numevt values 1, 2, 4, 8.

* ASoC: Davinci: Fix race with cpu_dai->dma_dataTroy Kisky2009-09-23
| | | | | | | | | | | This patch removes references to cpu_dai->dma_data. It makes struct davinci_pcm_dma_params part of struct davinci_mcbsp_dev or struct davinci_audio_dev. It removes the unused name variable from davinci_pcm_dma_params. Signed-off-by: Troy Kisky <troy.kisky@boundarydevices.com> Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
* ASoC: DaVinci: Fix divide by zero error during 1st executionTroy Kisky2009-09-23
| | | | | | | | | | | | When both playback and capture stream were open davinci_i2s_hw_params was setting parameters for the wrong stream. The fix for davinci_i2s_hw_params is sufficient, but it looks like a race still happens in davici_pcm_open. This patch also makes the race smaller but the next patch provides a better fix.

* ASoC: DaVinci: McASP driver enhacementsChaithrika U S2009-08-13
| | | | | | | | | | | | | | | | | | On DA830/OMAP-L137 and DA850/OMAP-L138 SoCs, the McASP peripheral has FIFO support. This FIFO provides additional data buffering. It also provides tolerance to variation in host/DMA controller response times. The read and write FIFO sizes are 256 bytes each. If FIFO is enabled, the DMA events from McASP are sent to the FIFO which in turn sends DMA requests to the host CPU according to the thresholds programmed. More details of the FIFO operation can be found at http://focus.ti.com/general/docs/lit/getliterature.tsp?literatureNumber= sprufm1&fileType=pdf This patch adds support for FIFO configuration. The platform data has a version field which differentiates the McASP on different SoCs.

* ASoC: make ops a pointer in 'struct snd_soc_dai'Eric Miao2009-03-04
| | | | | | | | | | | | | | | | Considering the fact that most cpu_dai or codec_dai are using a same 'snd_soc_dai_ops' for several similar interfaces, 'ops' would be better made a pointer instead, to make sharing easier and code a bit cleaner. The patch below is rather preliminary since the asoc tree is being actively developed, and this touches almost every piece of code, (and possibly many others in development need to be changed as well). Building of all codecs are OK, yet to every SoC, I didn't test that.

* ASoC: Register platform DAIsMark Brown2008-12-09
| | | | | | | | | | | Register all platform DAIs with the core. In line with current behaviour this is done at module probe time rather than when the devices are probed (since currently that only happens as the entire ASoC card is registered except for those drivers that currently implement some kind of hotplug). Since the core currently ignores DAI registration this has no practical effect. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>

* ASoC: Remove DAI type informationMark Brown2008-11-24
| | | | | | | | | | | 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.

* ASoC: Merge snd_soc_ops into snd_soc_dai_opsMark Brown2008-11-21
| | | | | | | | | | | | | 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.

* ASoC: Rename snd_soc_card to snd_soc_machineMark Brown2008-11-21
| | | | | | | | | | | | | | | | | 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.
