2013-05-30ASoC: blackfin: bf5xx-i2s: Add support for TDM modeLars-Peter Clausen
The bf5xx-i2s{,-pcm} and bf5xx-tdm{-pcm} drivers are nearly identical. Both are for the same hardware each supporting a slight different subset of the hardware. The bf5xx-i2s driver supports 2 channel I2S mode while the bf5xx-tdm driver supports TDM mode and channel remapping. This patch adds support for TDM mode and channel remapping to the bf5xx-i2s driver so that we'll eventually be able to retire the bf5xx-tdm driver. Unfortunately the hardware is fixed to using 8 channels in TDM mode. The bf5xx-tdm driver jumps through a few hoops to make it work well with other channel counts as well: * Don't support mmap * Translate between internal frame size (which is always 8 * sample_size) and ALSA frame size (which depends on the channel count) * Have special copy and silence callbacks which are aware of the mismatch between internal and ALSA frame size * Reduce the maximum buffer size to ensure that there is enough headroom for dummy data. The bf5xx-i2s driver is going to use the same mechanisms when being used int TDM mode.

2011-11-23ASoC: Constify snd_soc_dai_ops structsLars-Peter Clausen
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>
2011-03-30ASoC: Blackfin: push down SPORT settings from global variablesBarry Song
Now that we have multi-component support, take the time to unify the SPORT implementations a bit and make the setup dynamic. This kills off the global sport_handle which was shared across all the Blackfin machine drivers. The pin management aspect is off loaded to platform resources, and now multiple SPORTs can be instantiated simultaneously.

2011-03-30ASoC: Blackfin: standardize machine driver namesMike Frysinger
Some machine drivers were using "bf5xx-", others were using "bf5xx_", while others were using "bfin-". Further, some were using the same name in the transport layer which makes it hard to use different codecs at the same time. So standardize all of them to "bfin-" and make sure they are name spaced according to their driver name.

2010-08-12ASoC: multi-component - ASoC Multi-Component SupportLiam Girdwood
This patch extends the ASoC API to allow sound cards to have more than one CODEC and more than one platform DMA controller. This is achieved by dividing some current ASoC structures that contain both driver data and device data into structures that only either contain device data or driver data. i.e. struct snd_soc_codec ---> struct snd_soc_codec (device data) +-> struct snd_soc_codec_driver (driver data) struct snd_soc_platform ---> struct snd_soc_platform (device data) +-> struct snd_soc_platform_driver (driver data) struct snd_soc_dai ---> struct snd_soc_dai (device data) +-> struct snd_soc_dai_driver (driver data) struct snd_soc_device ---> deleted This now allows ASoC to be more tightly aligned with the Linux driver model and also means that every ASoC codec, platform and (platform) DAI is a kernel device. ASoC component private data is now stored as device private data. The ASoC sound card struct snd_soc_card has also been updated to store lists of it's components rather than a pointer to a codec and platform. The PCM runtime struct soc_pcm_runtime now has pointers to all its components. This patch adds DAPM support for ASoC multi-component and removes struct snd_soc_socdev from DAPM core. All DAPM calls are now made on a card, codec or runtime PCM level basis rather than using snd_soc_socdev. Other notable multi-component changes:- * Stream operations now de-reference less structures. * close_delayed work() now runs on a DAI basis rather than looping all DAIs in a card. * PM suspend()/resume() operations can now handle N CODECs and Platforms per sound card. * Added soc_bind_dai_link() to bind the component devices to the sound card. * Added soc_dai_link_probe() and soc_dai_link_remove() to probe and remove DAI link components. * sysfs entries can now be registered per component per card. * snd_soc_new_pcms() functionailty rolled into dai_link_probe(). * snd_soc_register_codec() now does all the codec list and mutex init. This patch changes the probe() and remove() of the CODEC drivers as follows:- o Make CODEC driver a platform driver o Moved all struct snd_soc_codec list, mutex, etc initialiasation to core. o Removed all static codec pointers (drivers now support > 1 codec dev) o snd_soc_register_pcms() now done by core. o snd_soc_register_dai() folded into snd_soc_register_codec().

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.

2008-12-09ASoC: 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.

2008-10-27ALSA: ASoC: Blackfin: update SPORT0 port selector (v2)Cliff Cai
- Setting the TFS pin selector for SPORT 0 based on whether the selected port id F or G. If the port is F then no conflict should exist for the TFS. When Port G is selected and EMAC then there is a conflict between the PHY interrupt line and TFS. Current settings prevent the conflict by ignoring the TFS pin when Port G is selected. This allows both ssm2602 using Port G and EMAC concurrently. - some code cleanup Signed-off-by: Cliff Cai <cliff.cai@analog.com> Signed-off-by: Bryan Wu <cooloney@kernel.org> Acked-by: Mark Brown <broonie@opensource.wolfsonmicro.com> Signed-off-by: Takashi Iwai <tiwai@suse.de>
