[PATCH AUTOSEL 5.13 177/219] soundwire: intel: fix potential race condition during power down

[PATCH AUTOSEL 5.13 088/219] ASoC: Intel: update sof_pcm512x quirks
by Sasha Levin 09 Sep '21

09 Sep '21

From: Pierre-Louis Bossart <pierre-louis.bossart(a)linux.intel.com> [ Upstream commit 22414cade8dfec25ab94df52b3a4f7aa8edb6120 ] The default SOF topology enables SSP capture and DMICs, even though both of these hardware capabilities are not always available in hardware (specific versions of HiFiberry and DMIC kit needed). For the SSP capture, this leads to annoying "SP5-Codec: ASoC: no backend capture" and "streamSSP5-Codec: ASoC: no users capture at close - state 0" errors. Update the quirks to match what the topology needs, which also allows for the ability to remove SSP capture and DMIC support.

[PATCH AUTOSEL 5.13 006/219] ASoC: ti: davinci-mcasp: Fix DIT mode support
by Sasha Levin 09 Sep '21

09 Sep '21

From: Peter Ujfalusi <peter.ujfalusi(a)gmail.com> [ Upstream commit bbdd3f4dbe81e19b9123bc54e23ed54517615524 ] The DIT mode support has not been tested due to lack of platform where it can be tested. To be able to use the McASP on OMAP4/5 (only supporting DIT mode) we need to have DIT mode working in the McASP driver on a know platform. After hacking around (on BBW, mcasp1.axr1 can be routed out for this) it appeared that DIT mode is broken. This patch fixes it up and 16/24 bit audio works along with passthrough, but I have only tested with DTS example and test files.

[PATCH AUTOSEL 5.14 224/252] ASoC: soc-pcm: protect BE dailink state changes in trigger
by Sasha Levin 09 Sep '21

09 Sep '21

From: Pierre-Louis Bossart <pierre-louis.bossart(a)linux.intel.com> [ Upstream commit 0c75fc7193387776c10f7c7b440d93496e3d5e21 ] When more than one FE is connected to a BE, e.g. in a mixing use case, the BE can be triggered multiple times when the FE are opened/started concurrently. This race condition is problematic in the case of SoundWire BE dailinks, and this is not desirable in a general case. The code carefully checks when the BE can be stopped or hw_free'ed, but the trigger code does not use any mutual exclusion. Fix by using the same spinlock already used to check FE states, and set the state before the trigger. In case of errors, the initial state will be restored. This patch does not change how the triggers are handled, it only makes sure the states are handled in critical sections.
