* ASoC: spear: constify snd_soc_dai_ops structuresJulia Lawall2017-08-151-1/+1
| | | | | | | | | | | These snd_soc_dai_ops structures are only stored in the ops field of a snd_soc_dai_driver structure, which is const. Thus, the snd_soc_dai_ops structures can be const too. Done with the help of Coccinelle. Signed-off-by: Julia Lawall <Julia.Lawall@lip6.fr> Signed-off-by: Mark Brown <broonie@kernel.org>

* ASoC: spear: fix error return code in spdif_in_probe()Gustavo A. R. Silva2017-07-171-2/+4
| | | | | | | | | | | | | | | platform_get_irq() returns an error code, but the spdif_in driver ignores it and always returns -EINVAL. This is not correct, and prevents -EPROBE_DEFER from being propagated properly. Notice that platform_get_irq() no longer returns 0 on error: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=e330b9a6bb35dc7097a4f02cb1ae7b6f96df92af Print error message and propagate the return value of platform_get_irq on failure.

* ASoC: SPEAr: remove custom DMA alloc compat functionStephen Warren2013-12-184-21/+24
| | | | | | | | | | | | | | | | | | 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 Warren2013-12-184-18/+41
| | | | | | | | | | | | | 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>

| | | | | | | | | | | | | | | | | | 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.

|\ | | | | | | | | | | | | | | | | | | | | | | 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().
