[PATCH 0/2] Kconfig symbol clean-up for sound
by Lukas Bulwahn 25 Nov '21

25 Nov '21

Dear sound maintainers, The script ./scripts/checkkconfigsymbols.py warns on invalid references to Kconfig symbols (often, minor typos, name confusions or outdated references). This is a patch series addressing the issues reported by ./scripts/checkkconfigsymbols.py in the ./sound/ directory for Kconfig files, quickly filtered down with: ./scripts/checkkconfigsymbols.py | grep "sound.*Kconfig" -B 1 This patch series addresses: SND_SOC_UNIPHIER_AIO_DMA Referencing files: sound/soc/uniphier/Kconfig SND_SOC_WCD937X Referencing files: sound/soc/codecs/Kconfig This patch series does not address: CLK_FIXED_FCH Referencing files: sound/soc/amd/Kconfig, sound/soc/amd/acp/Kconfig Rationale: config definition has been submitted, but is still pending for inclusion through another tree. SND_SOC_AC97_BUS_NEW Referencing files: sound/soc/pxa/Kconfig Rationale: waiting for response; the kernel developer has been informed here: https://lore.kernel.org/all/CAKXUXMzqgyNGEnxAMQqZiXJYSK-X8uB-nxHWwPg41H6yS0… Both patches in this series can be discussed and applied individually. They are sent in one patch series, as they orginate from the investigation guided by the same tool and hence share similar topics and resolutions. Please pick this series of minor clean-up patches. It applies cleanly on next-20211124. Best regards, Lukas Lukas Bulwahn (2): ASoC: uniphier: drop selecting non-existing SND_SOC_UNIPHIER_AIO_DMA ASoC: codecs: wcd938x: add SND_SOC_WCD938_SDW to codec list instead sound/soc/codecs/Kconfig | 3 +-- sound/soc/uniphier/Kconfig | 2 -- 2 files changed, 1 insertion(+), 4 deletions(-) -- 2.26.2

by Jayesh Choudhary 25 Nov '21

25 Nov '21

Convert the bindings for McASP controllers for TI SOCs from txt to YAML schema. Adds additional properties 'clocks', 'clock-names', 'power-domains' and '#sound-dai-cells' which were not there in txt file. Adds 'dmas' and 'dma-names' in the example which were not there in txt file. Changes 'interrupts' and 'interrupt-names' from optional to required properties.

sound: X86: Xilinx : PCIe : ALSA PCM sample driver code
by Muni Sekhar 25 Nov '21

25 Nov '21

Hi All, I am using a Linux X86 machine where Xilinx FPGA sound card connected to X86 machine's PCIe slot. The sound card supports PCM playback and capture capabilities. I need to write an ALSA driver for my sound card. Since I am using X86 machine and it don't have the devicetree, can someone please suggest the what driver architecture I should use for this type of sound card, also please point me to the ALSA driver reference code for this type of sound card. -- Thanks, Sekhar

[PATCH 00/11] dmaengine: kill off dma_slave_config->slave_id
by Arnd Bergmann 25 Nov '21

25 Nov '21

From: Arnd Bergmann <arnd(a)arndb.de> I recently came across some new uses of the 'slave_id' field that I had (almost) removed a few years ago. There are no legitimate uses of this field in the kernel, only a few stale references and two drivers that abuse the field as a side-channel between the dmaengine driver and its client. Let's change the xilinx and qualcomm drivers to use the documented side-channel (peripheral_data) instead, and remove the remnants of it to prevent new users from coming in. As the last patch in the series depends on all the others, it would be nice have everything merged into the dmaengine tree for v5.17.

Mediatek ADSP IPC is used to send notification or short message between processors with dsp. It will place the message to the share buffer and will access the ADSP mailbox registers to kick dsp.
