[PATCH v5 0/5] Add pin control support for lpass sc7280
by Srinivasa Rao Mandadapu 15 Dec '21

15 Dec '21

This patch series is to split lpass variant common pin control functions and SoC specific functions and to add lpass sc7280 pincontrol support. It also Adds dt-bindings for lpass sc7280 lpass lpi pincontrol. Changes Since V4: -- Update commit message and description of the chip specific extraction patch. -- Sort macros in kconfig and makefile. -- Update optional clock voting to conditional clock voting. -- Fix typo errors. -- Move to quicinc domain email id's. Changes Since V3: -- Update separate Kconfig fields for sm8250 and sc7280. -- Update module license and description. -- Move static variables to corresponding .c files from header file. Changes Since V2: -- Add new dt-bindings for sc7280 lpi driver. -- Make clock voting change as separate patch. -- Split existing pincontrol driver and make common functions as part of separate file. -- Rename lpass pincontrol lpi dt-bindings to sm8250 specific dt-bindings Changes Since V1: -- Make lpi pinctrl variant data structure as constant -- Add appropriate commit message -- Change signedoff by sequence.

[PATCH] ASoC: wcd934x: Fix a incorrect use of kstrndup
by Miaoqian Lin 14 Dec '21

14 Dec '21

In wcd934x_codec_enable_dec(), widget_name is allocated by kstrndup(). However, according to doc: "Note: Use kmemdup_nul() instead if the size is known exactly." So we should use kmemdup_nul() here instead of kstrndup(). It's similar to CVE-2019-12454.

[PATCH 0/5] ASoC: qcom: apq8016_sbc: Allow routing audio through QDSP6
by Stephan Gerhold 14 Dec '21

14 Dec '21

This series makes it possible to route audio through the combined audio/modem DSP on MSM8916/APQ8016 devices instead of bypassing it using the LPASS drivers. This is necessary to support certain functionality such as voice call audio. See PATCH 4/5 for details. Also, qcom,apq8016-sbc.txt is converted to DT schema by adding it to the existing qcom,sm8250.yaml. The bindings are similar enough that it is easier to share a single schema instead of duplicating everything into multiple ones.

[PATCH] ASoC: SOF: sof-probes: Constify sof_probe_compr_ops
by Rikard Falkeborn 14 Dec '21

The only usage of sof_probe_compr_ops is to assign its address to the cops field in the snd_soc_dai_driver struct (in sound/soc/sof/intel/hda-dai.c).

[PATCH v4] ASoC: dt-bindings: davinci-mcasp: convert McASP bindings to yaml schema
by Jayesh Choudhary 14 Dec '21

14 Dec '21

Convert the bindings for McASP controllers for TI SOCs from txt to YAML schema. Adds additional properties 'clocks', 'clock-names', 'power-domains', '#sound-dai-cells' and 'port' which were missing from txt file. Removes properties 'sram-size-playback' and 'sram-size-capture' since they are not used. Adds 'dmas' and 'dma-names' in the example which were missing from the txt file. Changes 'interrupts' and 'interrupt-names' from optional to required properties. Changes 'op-mode', 'serial-dir' and 'tdm-slots' to optional properties as they are not needed if the McASP is used only as GPIO. Adds the yaml file in the 'MAINTAINERS' under the heading 'TEXAS INSTRUMENTS ASoC DRIVERS' Signed-off-by: Jayesh Choudhary <j-choudhary(a)ti.com> --- Changelog: v4: - changes the commit message - adds type and description to relevant properties - changes maxItems for 'serial-dir' - removes properties 'sram-size-playback' and 'sram-size-capture' as they are not used - removes 'function-gpios' - removes 'num-serializer' - marks 'tdm-slots', 'serial-dir' and 'op-mode' as optional properties - adds the yaml file in MAINTAINERS v3: - removes maxItems from 'clock-names' v2: - changes the commit message - modifies the properties 'clocks', 'clock-names', 'dma-names', 'dmas', 'interrupts' and 'interrupt-names' according to the arm SOCs - adds 'ports' and 'num-serializer' as node properties .../bindings/sound/davinci-mcasp-audio.txt | 86 -------- .../bindings/sound/davinci-mcasp-audio.yaml | 185 ++++++++++++++++++ MAINTAINERS | 1 + 3 files changed, 186 insertions(+), 86 deletions(-) delete mode 100644 Documentation/devicetree/bindings/sound/davinci-mcasp-audio.txt create mode 100644 Documentation/devicetree/bindings/sound/davinci-mcasp-audio.yaml diff --git a/Documentation/devicetree/bindings/sound/davinci-mcasp-audio.txt b/Documentation/devicetree/bindings/sound/davinci-mcasp-audio.txt deleted file mode 100644 index bd863bd69501..000000000000 --- a/Documentation/devicetree/bindings/sound/davinci-mcasp-audio.txt +++ /dev/null @@ -1,86 +0,0 @@ -Texas Instruments McASP controller - -Required properties: -- compatible : - "ti,dm646x-mcasp-audio" : for DM646x platforms - "ti,da830-mcasp-audio" : for both DA830 & DA850 platforms - "ti,am33xx-mcasp-audio" : for AM33xx platforms (AM33xx, AM43xx, TI81xx) - "ti,dra7-mcasp-audio" : for DRA7xx platforms - "ti,omap4-mcasp-audio" : for OMAP4 - -- reg : Should contain reg specifiers for the entries in the reg-names property. -- reg-names : Should contain: - * "mpu" for the main registers (required).
