2015-03-04ASoC: davinci: Remove unused davinci-pcm platform driverPeter Ujfalusi1-41/+0
All DAI drivers has been converted to use edma-pcm instead of davinci-pcm and the driver can be removed from the tree. Signed-off-by: Peter Ujfalusi <> Signed-off-by: Mark Brown <>

Removes the DaVinci private SRAM API and replaces it with the genalloc API. The SRAM gen_pool is passed in pdata since DaVinci is in the early stages of DT conversion. [ stub out gen_pool functions for !CONFIG_GENERIC_ALLOCATOR] Signed-off-by: Matt Porter <> Signed-off-by: Mark Brown <>
2012-08-27ASoC/ARM: Davinci: McASP: split asp header into platform and audio specificHebbar, Gururaja1-2/+1
Davinci McASP header & driver are shared by few OMAP platforms (like TI81xx, AM335x). Splitting asp header into Davinci platform specific header and Audio specific header helps to share them across platforms. Audio specific defines is moved to to common <linux/platform_data/davinci_asp.h> so that the header can be accessed by all related platforms. While here, correct the header usage (remove multiple header re-definitions and unused headers) and remove platform names from structures comments and enum. Also some some coding style errors.

2012-08-27ASoC: davinci: davinci-pcm does not need to be a plaform_driverHebbar, Gururaja1-0/+3
Same as the commit 518de86 (ASoC: tegra: register 'platform' from DAIs, get rid of pdev). It makes davinci-pcm not a platform_driver but helper to register "platform", so that the platform_device for davinci-pcm can be saved completely.

2010-08-12ASoC: multi-component - ASoC Multi-Component SupportLiam Girdwood1-3/+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().

2010-07-20ASoC: davinci: let platform data define edma queue numbersSekhar Nori1-1/+2
Currently the EDMA queue to be used by for servicing ASP through internal RAM is fixed to EDMAQ_0 and that to service internal RAM from external RAM is fixed to EDMAQ_1. This may not be the desirable configuration on all platforms. For example, on DM365, queue 0 has large fifo size and is more suitable for video transfers. Having audio and video transfers on the same queue may lead to starvation on audio side. platform data as defined currently passes a queue number to the driver but that remains unused inside the driver. Fix this by defining one queue each for ASP and RAM transfers in the platform data and using it inside the driver. Since EDMAQ_0 maps to 0, thats the queue that will be used if the asp queue number is not initialized. None of the platforms currently utilize ping-pong transfers through internal RAM so that functionality remains unchanged too. This patch has been tested on DM644x and OMAP-L138 EVMs. Signed-off-by: Sekhar Nori <> Acked-by: Liam Girdwood <> Signed-off-by: Mark Brown <>
2009-11-19ASoC: DaVinci: pcm, fix underrun by using sramTroy Kisky1-0/+1
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. Signed-off-by: Troy Kisky <> Acked-by: Liam Girdwood <> Signed-off-by: Mark Brown <>
2009-09-30ASoC: DaVinci: McASP FIFO related updatesChaithrika U S1-0/+1
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.

2009-08-13ASoC: DaVinci: McASP driver enhacementsChaithrika U S1-0/+1
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 sprufm1&fileType=pdf This patch adds support for FIFO configuration. The platform data has a version field which differentiates the McASP on different SoCs. Signed-off-by: Chaithrika U S <> Signed-off-by: Mark Brown <>
2009-06-07ASoC: Add mcasp support for DM646xChaithrika U S1-8/+10
Adds driver support for the two instances of McASP on TI's DM646x. The multichannel audio serial port (McASP) functions as a general-purpose audio serial port optimized for the needs of multichannel audio application. ( There are two instances of McASP on DM646x. The McASP0 module includes up to 4 serializers that can be individually enabled to either transmit or receive in different modes. The McASP1 module is limited with only 1 pinned-out serializer that can be enabled to only transmit in DIT mode (neither receiving in any mode nor transmitting in either Burst or TDM mode is supported). McASP0 consists of transmit and receive sections that may operate synchronized, or completely independently with separate master clocks, bit clocks, and frame syncs, and using different transmit modes with different bit-stream formats.
