[PATCH] ASoC: da7219: Fix pole orientation detection on OMTP headsets when playing music
by David Rau 09 Feb '23

09 Feb '23

The OMTP pin define headsets can be mis-detected as line out instead of OMTP, causing obvious issues with audio quality. This patch is to put increased resistances within the device at a suitable point. To solve this issue better, the new mechanism setup ground switches with conditional delay control and these allow for more stabile detection process to operate as intended. This conditional delay control will not impact the hardware process but use extra system resource. This commit improves control of ground switches in the AAD logic.

[PATCH 0/2] ASoC: dt-bindings: renesas,rsnd.yaml: adjust to R-Car Gen4
by Kuninori Morimoto 09 Feb '23

09 Feb '23

Hi Mark, Rob, Krzysztof Cc Geert These are R-Car Gen4 support for Renesas sound driver. I have posted these patches as [RFC], because the schemas doesn't work correctly for me under certain conditions. "required: dmas/dma-names" always hits to "if-then" and never hits to "else" for some reasons. I'm still not sure why... But to be very strict, actually, this schemas is not mandatory, because there is PIO transfer mode which doesn't need to have DMA settings. Thus, this patch-set dropped the schemas for now, and ignore the issue, but it is *not* a wrong schemas IMO.

[PATCH] ASoC: dt-bindings: wlf,wm8994: Convert to dtschema
by Krzysztof Kozlowski 08 Feb '23

08 Feb '23

Convert the Wolfson WM1811/WM8994/WM8958 audio codecs bindings to DT schema. Changes against original binding: 1. Add missing LDO1VDD-supply for WM1811. 2. Use "gpios" suffix for wlf,ldo1ena and wlf,ldo2ena (Linux kernel's gpiolib already looks for both variants). 3. Do not require AVDD1-supply and DCVDD-supply, because at least on Arndale board with Exynos5250 these are grounded.

[PATCH v3 0/4] Add CS35L41 shared boost feature
by Lucas Tanure 08 Feb '23

08 Feb '23

Valve's Steam Deck uses CS35L41 in shared boost mode, where both speakers share the boost circuit. Add this support in the shared lib, but for now, shared boost is not supported in HDA systems as would require BIOS changes. Based on David Rhodes shared boost patches. Also, fix boost config overwriting in IRQ found in the review and do a small refactor of the code. Changes from V2: - Drop External boost without VSPK Documentation - Move Shared boost to use values 2 and 3 - Revert back to reg_sequence but reading the value first and only update the necessary bits - Fix bug found by Intel kernel Test Robot Changes from V1: - Fix Documentation patch subject - New patch for External boost without VSPK Documentation - New patch to fix boost IRQ overwriting issue - New patch to refactor IRQ release error code - reinit_completion on pcm_startup - fix DRE switch overwriting - return IRQ_HANDLED in PLL_LOCK case Lucas Tanure (4): ASoC: cs35l41: Only disable internal boost ASoC: cs35l41: Refactor error release code ALSA: cs35l41: Add shared boost feature ASoC: cs35l41: Document CS35l41 shared boost .../bindings/sound/cirrus,cs35l41.yaml | 10 +- include/sound/cs35l41.h | 13 +- sound/pci/hda/cs35l41_hda.c | 6 +- sound/soc/codecs/cs35l41-lib.c | 69 +++++++++- sound/soc/codecs/cs35l41.c | 125 +++++++++--------- sound/soc/codecs/cs35l41.h | 1 + 6 files changed, 153 insertions(+), 71 deletions(-) -- 2.39.1
