2009-03-04ASoC: make ops a pointer in 'struct snd_soc_dai'Eric Miao
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.

2008-12-20ALSA: ASoC: DaVinci: document I2S limitationsTroy Kisky
DaVinci does not support true I2S or right justified mode so not all I2S codecs will work with it when the codec is master. Document this limitation.

2008-12-09ASoC: Register platform DAIsMark Brown
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>

2008-11-24ASoC: Remove DAI type informationMark Brown
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.

2008-11-21ASoC: Merge snd_soc_ops into snd_soc_dai_opsMark Brown
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.

2008-11-21ASoC: Rename snd_soc_card to snd_soc_machineMark Brown
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.
