[alsa-devel] simple card, asymetrical configuration
by Michael Walle 03 Dec '19

03 Dec '19

Hi Kuninori, there seems to be a problem in the simple-card using the following device tree fragment: sound { compatible = "simple-audio-card"; simple-audio-card,format = "i2s"; [snip] simple-audio-card,bitclock-master = <&dailink0_master>; simple-audio-card,frame-master = <&dailink0_master>; simple-audio-card,cpu@0 { sound-dai = <&sai6>; }; simple-audio-card,cpu@1 { sound-dai = <&sai5>; }; dailink0_master: simple-audio-card,codec { sound-dai = <&wm8904>; }; }; Just for the background, I have hardware with the LS1028A which only have unidirectional SAIs. But two of those SAIs (one for playback and one for capture) are connected to one codec (with a shared bit and frame clock). So I thought the example in the simple-card bindings makes sense for my case. Although I don't really know what "(Mixing)" means. Nevertheless, using the fragment above, the kernel oopses or fails to probe the hardware. I've traced that back to the following: - the count is correct: the kernel reports "link 2, dais 3, ccnf 0". please note the 3 dais here. - but simple_dai_link_of() will always "allocate" two dais from the pool: cpu_dai = dai_props->cpu_dai = &priv->dais[li->dais++]; codec_dai = dai_props->codec_dai = &priv->dais[li->dais++]; While this still works for the first link, the second one will fail because codec_dai will not be valid. Btw, converting that to two explicit dai-link nodes, the dai count will be 4 and it will work. Is my use case correct or should I use the two explicit dai-link nodes? But in any case there seems to be a bug in simple-card. -michael

[alsa-devel] [PATCH 00/10] ASoC: SOF: initial cleanup for DT and multi-client support
by Pierre-Louis Bossart 03 Dec '19

This series does not add new functionality but introduces a better code partition to support machine drivers in Device Tree, as well as a 'componentization' of the PCM/topology parts needed for multi-client support. This cleanup was merged in the SOF tree and tested extensively with no regressions identified. Thanks Ranjani and Daniel for combining your proposals in a single change.

[alsa-devel] Integrating Texes Instruments PCM1860 ADC
by Umar Dockrat 02 Dec '19

02 Dec '19

Good Day, I have been struggling with the integration of a PCM1860 ADC for audio recording. I have created a "sound card" board that contains both a PCM5102A (DAC) and PCM1860 (ADC). The main processor is an Omega Onion 2 which is based on MediaTek MT7688 SoC device. I am struggling with creating the device tree as the Kernel currently has reference to the PCM186X where X is 2,3,4 or 5 but not the more simple PCM1860. The difference between the PCM1860 and the PCM186X is that the PCM1860 does not have I2C control and is HW configured using pull up/down. https://www.kernel.org/doc/Documentation/devicetree/bindings/sound/pcm186x.… I have tried multiple device tree setup's and have only got the DAC working when configured in isolation, as soon as I add any reference to the ADC then both DAC and ADC are not recognised. This DTSI allows the DAC to function https://pastebin.com/z9H67DHd There are my attempts at including the DAC and ADC: https://pastebin.com/RLsKNsiR https://pastebin.com/rmJVcCz1 Please can someone assist with the correct way to integrate this ADC device? Any suggestions on how to properly debug this further is also really appreciated. Thanks, UFD

When system wide suspend happens, ACP will be powered off and when system resumes,for audio usecase to continue,all the runtime configuration data needs to be programmed again.

[alsa-devel] [PATCH v13 5/7] ASoC: amd: Handle ACP3x I2S-SP Interrupts.
by Ravulapati Vishnu vardhan rao 02 Dec '19
