2013-08-15ALSA: move dmaengine implementation from ASoC to ALSA coreDaniel Mack1-1/+1
For the PXA DMA rework, we need the generic dmaengine implementation that currently lives in sound/soc for standalone (non-ASoC) AC'97 support. Move it to sound/core, and rename the Kconfig symbol. Signed-off-by: Daniel Mack <zonque@gmail.com> Signed-off-by: Mark Brown <broonie@linaro.org>
2013-06-17ASoC: spear: Convert to use devm_ioremap_resourceTushar Behera1-15/+4
Commit 75096579c3ac ("lib: devres: Introduce devm_ioremap_resource()") introduced devm_ioremap_resource() and deprecated the use of devm_request_and_ioremap(). devm_request_mem_region is called in devm_ioremap_resource(). Hence that part can also be removed. Since devm_ioremap_resource prints error message on failure, there is no need to print an explicit warning message.

2013-06-14ASoC: SPEAr: Hide component drivers in KconfigMark Brown1-13/+3
The individual component drivers are only useful with a machine driver and should be selected by the machine drivers so shouldn't have help text of their own in order to hide them in interactive configuration. Signed-off-by: Mark Brown <broonie@linaro.org>

2013-06-13ASoC: SPEAr spdif_{in,out}: fix fallout of previous cleanupUwe Kleine-König2-19/+3
The patch that resulted in bfcc74e (ASoC: SPEAr spdif_{in,out}: use devm for clk and a few more cleanups) was broken and applied on a newer tree than it was created for. So bfcc74e introduced unbalanced clk handling, two warnings about unused variables and passed 3 arguments to a function only taking 2. This commit fixes that.

2013-04-18Merge tag 'asoc-v3.10-2' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound into for-nextTakashi Iwai1-2/+3
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 Clausen1-2/+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().

2013-03-26ASoC: spear_pcm: No need to wrap snd_dmaengine_pcm_close()Lars-Peter Clausen1-9/+1
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.
