ASoC: amd: Fix simultaneous playback and capture

2020-01-29T17:48:47+00:00

Stopping of one stream is killing the other stream when they are running simultaneously. This is because, IER register is cleared which disables I2S and overrides any other block enables. Clearing IER register only when all streams on a channel are disabled, fixes the issue.

ASoC: amd: Fix for Subsequent Playback issue.

2020-01-27T17:51:48+00:00

If we play audio back to back, which kills one playback and immediately start another, we can hear clicks. This patch fixes the issue.

ASoC: amd: Additional DAI for I2S SP instance.

2020-01-17T15:31:24+00:00

I2S SP instance has separate BCLK and LRCLK for Tx and Rx. Creating additional DAI for Rx. Signed-off-by: Ravulapati Vishnu vardhan rao Link: https://lore.kernel.org/r/1579261510-12580-1-git-send-email-Vishnuvardhanrao.Ravulapati@amd.com Signed-off-by: Mark Brown

ASoC: amd: acp3x: Fix return value check in acp3x_dai_probe()

2020-01-09T13:23:43+00:00

In case of error, the function devm_ioremap() returns NULL pointer not ERR_PTR(). The IS_ERR() test in the return value check should be replaced with NULL test.

ACP-I2S device support MMAP_INTERLEAVED. Added support for the same. Signed-off-by: Ravulapati Vishnu vardhan rao Link: https://lore.kernel.org/r/1577540460-21438-7-git-send-email-Vishnuvardhanrao.Ravulapati@amd.com Signed-off-by: Mark Brown

ASoC: amd: Added ACP3x system resume and runtime pm

2019-12-31T00:23:15+00:00

When system wide suspend happens, ACP will be powered off and when system resumes,for audio usecase to continue,all the runtime configuration data needs to be programmed again. Added resume pm call back to ACP pm ops and also added runtime PM operations for ACP3x PCM platform device. Device will enter into D3 state when there is no activity on audio I2S lines.

ASoC: amd: Handle ACP3x I2S-SP Interrupts.

2019-12-31T00:22:59+00:00

Enabled support for I2S-SP interrupt handling. Previous to this implementation, driver supports only interrupts on BT instance.

ASoC: amd: add ACP3x TDM mode support

2019-12-31T00:22:43+00:00

ACP3x I2S (CPU DAI) can act in normal I2S and TDM modes. Added support for TDM mode. Desired mode can be selected from ASoC machine driver.

ASoC: amd: Enabling I2S instance in DMA and DAI

2019-12-31T00:22:28+00:00

This patch adds I2S SP support in ACP PCM DMA and DAI. Added I2S support in DMA and DAI probe,its hw_params handling its open and close functionalities. This enables to open and close on the SP instance for playback and capture.
