2009-08-11Merge commit 'a5479e389e989acfeca9c32eeb0083d086202280' into for-2.6.32Mark Brown1-2/+3
2009-08-09ASoC: Define more formats for the AC97 CODECsMark Brown1-1/+7

2009-08-06ASoC: change set_tdm_slot api to allow slot_width override.Daniel Ribeiro1-2/+3
Extend set_tdm_slot to allow the user to arbitrarily set the frame width and active TX/RX slots. Updates magician.c and wm9081.c for the new set_tdm_slot(). wm9081.c still doesn't handle the slot_width override. While being there, correct an incorrect use of SlotsPerFrm(7) use in bitmask on pxa-ssp.c (SSCR0_SlotsPerFrm(x) is (((x) - 1) << 24)) ). (this series is meant for Mark's for-2.6.32 branch) Signed-off-by: Daniel Ribeiro <drwyrm@gmail.com> Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
2009-07-23ALSA: Allow passing platform_data to devices attached to AC97 busMarek Vasut1-0/+1
This patch allows passing platform_data to devices attached to AC97 bus (like touchscreens, battery measurement chips ...). Signed-off-by: Marek Vasut <marek.vasut@gmail.com> Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>

2009-05-05ASoC: Remove redundant codec pointer from DAIsMark Brown1-5/+2
The DAI structure has two pointers to the codec, one in the body of the DAI and one in a union for a parent pointer. Drop the parent pointer version. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
2009-05-02ASoC: Remove unused DAI format definesMark Brown1-18/+0
The defines for TDM and synchronous clocks are not used - they are mostly a legacy of the automatic clocking configuration. TDM will require configuration of the number of timeslots and which ones to use so can't be fit into the DAI format and synchronous mode is handled by symmetric_rates (and needs to be done by constraints rather than when the DAI format is being configured).

2009-05-02ASoC: Use a shared define for AC97 CODEC data formatsMark Brown1-0/+3
The AC97 wire format is completely fixed so CODECs don't have any choice about the formats they accept but controllers accept a variety of data formats and render them down onto the bus. Have a shared define so all the CODEC drivers will interoperate with any of our controller drivers. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
2009-04-07ASoC: Provide core support for symmetric sample ratesMark Brown1-0/+1
Many devices require symmetric configurations of capture and playback data formats, often due to shared clocking but sometimes also due to other shared playback and record configuration in the device. Start providing core support for this by allowing the DAIs or the machine to specify that the sample rates used should be kept symmetric. A flag symmetric_rates is provided in the snd_soc_dai and snd_soc_dai_link structures. If this is set in either of the DAIs or in the machine then a constraint will be applied when a stream is already open preventing any changes in sample rate.

2009-03-05ASoC: make ops a pointer in 'struct snd_soc_dai'Eric Miao1-1/+1
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.

2008-12-09ASoC: Add DAI registration APIMark Brown1-0/+8
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>
2008-12-03ASoC: Remove platform device from DAI suspend and resume operationsMark Brown1-4/+2
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>
2008-11-24ASoC: Remove DAI type informationMark Brown1-1/+1
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 Brown1-2/+18
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: Move DAI structure definitions into new soc-dai.hMark Brown1-0/+209
ASoC v2 factors most of the contents of soc.h out into separate headers, including soc-dai.h for the DAI. Factor the existing DAI API out into this file in order to prepare for backporting of the ASoC v2 DAI API. Also backport some of Liam's improvements to the documentation.
