2015-02-09ASoC: atmel_ssc_dai: fix start event for I2S modeBo Shen1-14/+4
commit a43bd7e125143b875caae6d4f9938855b440faaf upstream. According to the I2S specification information as following: - WS = 0, channel 1 (left) - WS = 1, channel 2 (right) So, the start event should be TF/RF falling edge.

2013-08-06ASoC: atmel: machine driver for at91sam9x5-wm8731 boardsNicolas Ferre3-0/+220
Description of the Asoc machine driver for an at91sam9x5 based board with a wm8731 audio DAC. Wm8731 is clocked by a crystal and used as a master on the SSC/I2S interface. Its connections are a headphone jack and an Line input jack.

2013-04-18Merge tag 'asoc-v3.10-2' of ↵Takashi Iwai1-3/+3
git://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound into for-next ASoC: More updates for v3.10 The main additional change here is Lars-Peter's DMA work plus the platform conversions which have been tested - getting this in mainline will make life easier for development after the merge window. These factor a large chunk of code out of the drivers for the platforms using dmaengine, greatly simplifying development.
2013-04-17ASoC: dmaengine-pcm: Make requesting the DMA channel at PCM open optionalLars-Peter Clausen1-3/+3
Refactor the dmaengine PCM library to allow the DMA channel to be requested before opening a PCM substream. snd_dmaengine_pcm_open() now expects a DMA channel instead of a filter function and filter parameter as its parameters. snd_dmaengine_pcm_close() is updated to not release the DMA channel. This allows a dmaengine based PCM driver to request its channels before the substream is opened. The patch also introduces two new functions, snd_dmaengine_pcm_open_request_chan() and snd_dmaengine_pcm_close_release_chan(), which have the same signature and behaviour of the old snd_dmaengine_pcm_{open,close}() and internally use the new variants of these functions. All users of snd_dmaengine_pcm_{open,close}() are updated to use snd_dmaengine_pcm_open_request_chan() and snd_dmaengine_pcm_close_release_chan().

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.
