2011-09-26ASoC: omap-mcpdm: API to configure offset cancellationPeter Ujfalusi1-0/+12
The offset cancellation values can be different from board to board, even on the same HW platform. Provide a way for the machine drivers to configure the McPDM offset cancellation. Signed-off-by: Peter Ujfalusi <peter.ujfalusi@ti.com> Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
2011-09-22ASoC: omap-mcpdm: Replace legacy driverMisael Lopez Cruz1-0/+95
Reasons for the replacement: The current driver for McPDM was developed to support the legacy mode only. In preparation for the ABE support the current driver stack need the be replaced. The new driver is much simpler, easier to extend, and it also fixes some of the issues with the old stack. Main changes: - single file for omap-mcpdm (mcpdm.c/h removed) - Define names for registers, bits cleaned up, prefixed - Full-duplex audio operation (arecord | aplay) has been fixed - Less code McPDM need to be turned off after all streams has been stopped. This might cause pop noise on the output, if the codec's DAC is still powered at this time.

2010-08-12ASoC: multi-component - ASoC Multi-Component SupportLiam Girdwood1-29/+0
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().

2010-02-23ASoC: OMAP4: Add McPDM platform driverMisael Lopez Cruz1-0/+29
McPDM platform driver is configured to use sDMA in order to transfer to/from memory. Support for interfacing with ABE will be added later. McPDM dai currently supports up to 4 downlink channels and 2 uplink channels simultaneously, as well as 88.2 and 96 KHz, and a sample size of 32 bits.
