* ASoC: spear_pcm: Use devm_snd_dmaengine_pcm_register to fix resource leakAxel Lin2015-08-301-1/+1
| | | | | | | | | All the callers assume devm_spear_pcm_platform_register is a devm_ API, so use devm_snd_dmaengine_pcm_register in devm_spear_pcm_platform_register.

* ASoC: SPEAr: remove custom DMA alloc compat functionStephen Warren2013-12-181-14/+7
| | | | | | | | | | | | | | | | | | spear_pcm_request_chan() is almost identical to dmaengine_pcm_compat_request_channel(), with the exception that the latter: a) Assumes that the DAI DMA data is a struct snd_dmaengine_dai_dma_data pointer rather than some custom type. b) dma_data->filter_data rather than dma_data should be passed to snd_dmaengine_pcm_request_channel() as the filter data. Make minor changes to the SPEAr DAI drivers so that those two conditions are met. This allows removal of the custom .compat_request_channel().

* ASoC: SPEAr: get rid of spear-pcm-audio struct deviceStephen Warren2013-12-181-14/+4
| | | | | | | | | | | | | Modify the SPEAr PCM driver so that it's a utility library that can be registered on each DAI, rather than a separate struct device. This is more in line with how many recent DT-converted platforms operate, and avoids the need for yet another struct device. This is also required as a pre-cursor to removing spear_pcm_request_chan(). Signed-off-by: Stephen Warren <swarren@nvidia.com> Signed-off-by: Mark Brown <broonie@linaro.org>

* Merge tag 'asoc-v3.10-2' of ↵Takashi Iwai2013-04-181-2/+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.

| * | ASoC: dmaengine-pcm: Make requesting the DMA channel at PCM open optionalLars-Peter Clausen2013-04-171-2/+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().

| |/ | | | | | | | | | | | | | | | | | | | | If a PCM driver using the dmaengine PCM helper functions doesn't need to do anything special in its pcm_close callback, snd_dmaengine_pcm_close can be used directly for as the pcm_close callback and there is no need to wrap it in a custom function.

|/ | | | | | | | | | | | Commit 552d1ef6 ("ASoC: core - Optimise and refactor pcm_new() to pass only rtd") updated the pcm_new() callback to take the rtd as the only parameter. The spear PCM driver (which was merged much later) still uses the old API. This patch updates the driver to the new API.
