[PATCH AUTOSEL 6.1 03/53] ASoC: SOF: pm: Always tear down pipelines before DSP suspend

Hi, This series contains one fix (first patch) followed by a nice to have safety belts in case we get a widget from topology which is not handled by SOF and will not have corresponding swidget associated with. I think these can be sent selectively to stable kernels with appropriate adjustments to apply. I was not comfortable to add Fixes or Complements tags since the last patch for sure going to conflict in some stable variants.

[PATCH v3 0/5] ASoC: samsung: fsd: audio support for FSD SoC
by Padmanabhan Rajanbabu 16 Jan '23

16 Jan '23

This patch series enables audio support on FSD SoC. Changes in v3: 1. Addressed all the review comments provided for v2 patch. 2. Fixed compilation warnings reported by kernel test robot. Changes in v2: 1. New compatible added in Exynos I2S driver for FSD platform. 2. Added Fixup support for Exynos I2S CPU DAI. 3. Migration of manual PSR, OPCLK configuration to Exynos CPU DAI driver as fixup. 4. Migrated from dedicated sound card to simple audio card. 5. Support added for tlv320aic3x-i2c codec on FSD platform. Changes in v1: 1. Add TDM support on samsung I2S interface. 2. Allow sound card to directly configure I2S prescaler divider instead of calculating it from frame clock. 3. The sound card support for FSD SoC which utilizes samsung I2S interface as CPU DAI.

[PATCH] ucm: add existence checks to geti calls

15 Jan '23

From: Curtis Malainey <cujomalainey(a)chromium.org> Right now in snd_use_case_geti you cannot tell if the item being queried exists or not when being checked. This also means the only way to check for the existence of something in the client of the library is to iterate over the list of mods/devs even if we know exactly the name we are looking for. We have functions that do exactly this internally so lets return this information in a logical fashion through geti.
