Merge tag 'asoc-v5.7' of https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound into for-linus

2020-03-30T11:43:00Z

ASoC: Updates for v5.7 This is a very big update for the core since Morimoto-san has been rather busy continuing his refactorings to clean up a lot of the cruft that we have accumilated over the years. We've also gained several new drivers, including initial (but still not complete) parts of the Intel SoundWire support. - Lots of refactorings to modernize the code from Morimoto-san. - Conversion of SND_SOC_ALL_CODECS to use imply from Geert Uytterhoeven. - Continued refactoring and fixing of the Intel support. - Soundwire and more advanced clocking support for Realtek RT5682. - Support for amlogic GX, Meson 8, Meson 8B and T9015 DAC, Broadcom DSL/PON, Ingenic JZ4760 and JZ4770, Realtek RL6231, and TI TAS2563 and TLV320ADCX140.

ALSA: dmaengine_pcm: No need to take runtime reference twice in pcm_pointer

2020-03-06T15:02:51Z

The runtime pointer has been taken in functional level so there is no need to take it again under the if () case.

ALSA: dmaengine_pcm: Consider DMA cache caused delay in pointer callback

2020-02-11T15:42:31Z

Some DMA engines can have big FIFOs which adds to the latency. The DMAengine framework can report the FIFO utilization in bytes. Use this information for the delay reporting.

ASoC: pcm_dmaengine: Extract snd_dmaengine_pcm_refine_runtime_hwparams

2019-10-01T11:18:25Z

When set the runtime hardware parameters, we may need to query the capability of DMA to complete the parameters. This patch is to Extract this operation from dmaengine_pcm_set_runtime_hwparams function to a separate function snd_dmaengine_pcm_refine_runtime_hwparams, that other components which need this feature can call this function.

ASoC: dmaengine_pcm: Add support for packed transfers

2016-04-27T16:34:11Z

dmaengine_pcm currently only supports setups where FIFO reads/writes correspond to exactly one sample, eg 16-bit sample data is transferred via 16-bit FIFO accesses, 32-bit data via 32-bit accesses. This patch adds support for setups with fixed width FIFOs where multiple samples are packed into a larger word. For example setups with a 32-bit wide FIFO register that expect 16-bit sample transfers to be done with the left+right sample data packed into a 32-bit word. Support for packed transfers is controlled via the SND_DMAENGINE_PCM_DAI_FLAG_PACK flag in snd_dmaengine_dai_dma_data.flags If this flag is set dmaengine_pcm doesn't put any restriction on the supported formats and sets the DMA transfer width to undefined. This means control over the constraints is now transferred to the DAI driver and it's responsible to provide proper configuration and check for possible corner cases that aren't handled by the ALSA core.

ALSA: pcm_dmaengine: Properly synchronize DMA on shutdown

2015-11-16T02:58:52Z

Use the new dmaengine_synchronize() function to make sure that all complete callbacks have finished running before the runtime data, which is accessed in the completed callback, is freed. This fixes a long standing use-after-free race condition that has been observed on some systems. Signed-off-by: Lars-Peter Clausen Reviewed-by: Takashi Iwai Signed-off-by: Vinod Koul
