2011-11-23ASoC: Tegra PCM: Use module_platform_driverStephen Warren
This saves some boiler-plate code. Signed-off-by: Stephen Warren <swarren@nvidia.com> Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
2011-10-17ASoC: Tegra: sparse cleanupOlof Johansson
Fixes the following sparse warnings: sound/soc/tegra/tegra_das.c:215:8: warning: Using plain integer as NULL pointer sound/soc/tegra/tegra_das.c:237:8: warning: Using plain integer as NULL pointer sound/soc/tegra/tegra_pcm.c:370:32: warning: symbol 'tegra_pcm_platform' was not declared. Should it be static? Signed-off-by: Olof Johansson <olof@lixom.net> Acked-by: Stephen Warren <swarren@nvidia.com> Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
2011-08-09ASoC: Tegra: tegra_pcm_deallocate_dma_buffer: Don't OOPSStephen Warren
Not all PCM devices have all sub-streams. Specifically, the SPDIF driver only supports playback and hence has no capture substream. Check whether a substream exists before dereferencing it, when de-allocating DMA buffers in tegra_pcm_deallocate_dma_buffer.

2011-06-07ASoC: core - Optimise and refactor pcm_new() to pass only rtdLiam Girdwood
Currently pcm_new() passes in 3 arguments :- card, pcm and DAI. Refactor this to only pass in 1 argument (i.e. the rtd) since struct rtd contains card, pcm and DAI along with other members too that are useful too.

2011-02-28ASoC: Tegra: Fix error handling in DMA channel allocStephen Warren
tegra_dma_allocate_channel() returns NULL on errors, not an error pointer. Signed-off-by: Stephen Warren <swarren@nvidia.com> Acked-by: Liam Girdwood <lrg@slimlogic.co.uk> Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
2011-02-13ASoC: Tegra: Add MODULE_ALIASStephen Warren
With the appropriate MODULE_ALIAS in place, the audio modules will be automatically loaded; there is no longer a need for manual modprobes. Signed-off-by: Stephen Warren <swarren@nvidia.com> Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
2011-01-10ASoC: tegra: Add tegra-pcm driverStephen Warren
This provides an ASoC platform driver that manages Tegra's APB DMA controller. Signed-off-by: Stephen Warren <swarren@nvidia.com> Acked-by: Liam Girdwood <lrg@slimlogic.co.uk> Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
