[PATCH] ASoC: dt-bindings: davinci-mcasp: Fix interrupt properties
by Miquel Raynal 07 Oct '24

07 Oct '24

Combinations of "tx" alone, "rx" alone and "tx", "rx" together are supposedly valid (see link below), which is not the case today as "rx" alone is not accepted by the current binding. Let's rework the two interrupt properties to expose all correct possibilities.

A devm_kzalloc() in asoc_qcom_lpass_cpu_platform_probe() could possibly return NULL pointer. NULL Pointer Dereference may be triggerred without addtional check. Add a NULL check for the returned pointer.

[PATCH v2 0/7] qrb4210-rb2: add HDMI audio playback support
by Alexey Klimov 06 Oct '24

06 Oct '24

Rebased on top of -master, tested. Changes since v1: -- removed handling of MI2S clock in sm2450_snd_shutdown(): setting clock rate and disabling it causes audio delay on playback start; -- removed empty sound { } node from sm6115.dtsi as suggested by Krzysztof; -- moved lpi_i2s2_active pins description to qrb423310 board-specific file as suggested by Dmitry Baryshkov; -- moved q6asmdai DAIs to apr soc node as suggested by Konrad Dybcio; -- lpass_tlmm is not disabled; -- lpass_tlmm node moved to sm4250.dtsi; -- kept MultiMedia DAIs as is, without them the sound card driver doesn't initialise; -- added some reviewed-by tags. This series still keeps "qcom,qrb4210-rb2-sndcard" for sm8250 soundcard. As per off the list discussion with Srini it was suggested to have it since in future it may be required to add clocks, workarounds, quirks, model-specific things based on this compatible. The same as for RB5 compatible in sm8250 snd driver. This focuses on HDMI audio playback only hence there are no soundwire and dmic pins, for instance. The work to enable playback via wcd+wsa8815 amplifier is in progress (it works) and one of the routes is to merge such two patchsets together.

[PATCH] sound: soc: uniphier: Handle regmap_write errors in aio_src_set_param()
by (학생) 장인규 (컴퓨터공학과) 05 Oct '24

05 Oct '24

From 791716bf359b8540c519810848fd1f8006d7c3c5 Mon Sep 17 00:00:00 2001 From: Ingyu Jang <ingyujang25(a)unist.ac.kr> Date: Thu, 26 Sep 2024 19:40:04 +0900 Subject: [PATCH] sound: soc: uniphier: Handle regmap_write errors in aio_src_set_param() The aio_src_set_param() function did not previously check the return values of regmap_write() and regmap_update_bits(). If these functions fail, it could lead to silent failures when configuring the sample rate converter (SRC), causing improper behavior in audio processing without any indication of an error. This patch modifies aio_src_set_param to check the return values of regmap_write() and regmap_update_bits(). If either function returns an error, the error code is propagated back to the caller to ensure proper error handling. This change aligns with the existing error-handling behavior in functions like uniphier_aio_prepare(), where a failure in a sub-function should result in an immediate return of the error.
