[PATCH] ASoC: rt1015: remove possible unused variable `bclk_ms'
by Tzung-Bi Shih 23 Aug '21

23 Aug '21

bclk_ms is possible unused by using the given config (see [1]). sound/soc/codecs/rt1015.c:724:2: warning: Value stored to 'bclk_ms' is never read [clang-analyzer-deadcode.DeadStores] bclk_ms = frame_size > 32; ^ ~~~~~~~~~~~~~~~ In addition, bclk_ms is meaningless and confusing after applying commit a5db2ca51367 ("ASoC: rt1015: remove unneeded variables in rt1015_priv"). The "> 32" in the expression looks like a typo but it was not. Let's remove the confusing variable bclk_ms.

[PATCH 00/11] ASoC: Intel: Skylake: Fix and support complex

Existing skylake-driver supports very basic scenarios with limited range of modules and their control.

[PATCH 2/2] plugio: Check for pointer callback error codes

By checking error code returned by the pointer callback, we can determine more precisely PCM state. Previous implementation assumed, that a software PCM can only produce overrun or underrun. It was impossible to mark software PCM as disconnected.

[PATCH v2 0/3] soundwire: intel: exit clock-stop mode before system suspend
by Bard Liao 23 Aug '21

23 Aug '21

Intel validation reported an issue where the HW_RST self-clearing bit is not cleared in hardware, which as a ripple effect creates issues with the clock stop mode. This happens is a specific sequence where the Intel manager is pm_runtime suspended with the clock-stop mode enabled. During the system suspend, we currently do nothing, which can lead to potential issues on system resume and the following pm_runtime suspend, depending on the hardware state. This patch suggests a full resume if the clock-stop mode is used. This may require extra time but will make the suspend/resume flows completely symmetric. This also removes a race condition where we could not access SHIM registers if the parent was suspended as well. Resuming the link also resumes the parent by construction. BugLink: https://github.com/thesofproject/linux/issues/2606 v2: - Better comments and commit messages. - Modified the .prepare callback to only deal with the corner case that is NOT covered today instead of systematically doing a full resume.

[PATCH for-5.15] ASoC: intel: atom: Revert PCM buffer address setup workaround again

We worked around the breakage of PCM buffer setup by the commit 65ca89c2b12c ("ASoC: intel: atom: Fix breakage for PCM buffer address setup"), but this isn't necessary since the CONTINUOUS buffer type also sets runtime->dma_addr since commit f84ba106a018 ("ALSA: memalloc: Store snd_dma_buffer.addr for continuous pages, too").
