[alsa-devel] Prepare to covert Codec/Platform into Component
by Kuninori Morimoto 09 May '18

09 May '18

Hi Mark, Lars-Peter I will post all prepare patches to convert Codec/Platform into Component. It has 3 steps. 1) add new necessary functions 2) remove/don't use codec hw_write/read 3) remove/don't use codec reg_cache If these are accepted, all prepares were completed. Next, I can post "convert Codec/Platform into Component" patch bomb. These are too many convert patches, to avoid review issue, I will post few of them as sample. 4) sample of don't use rtd->codec 5) sample of convert Platform into Component 6) sample of convert Codec into Component I will post some of "remove" patches too for each steps. I will re-post all "remove" patches if all are accepted. For your review, please consider below. If these are not good, all covert patch doesn't work. 1. use devm_snd_soc_register_component() and remove snd_soc_unregister_component() My patches is using devm_ version function, and removed unregister function. This is not a big deal 2. New flags. Because "Codec" and "CPU/Platform" are using different features, we need to use some new flags. .idle_bias_off/on .ignore_pmdown_time/pmdown_time These are because "CPU/Platform" and "Codec" are using different default value. "Codec" side convert patches are using these. .endianness .non_legacy_dai_naming These are because "Codec" only needs fixup format, and not use "legacy" DAI name. "Codec" side convert patches are using these I added its flags info on each patch. 3. rtd->platform rtd->platform will be removed. Now we can find all rtd connected component by using rtdcom_lookup. rtd->platform will be replaced to snd_soc_rtdcom_lookup(rtd, DRV_NAME); Here, DRV_NAME is platform's component driver name. 4. rtd->codec rtd->codec will be removed. In soc_bind_dai_link(), It is rtd->codec = rtd->codec_dai->codec; And now, DAI has codec and component pointer. So, rtd->codec will be replaced into rtd->codec_dai->component.

[alsa-devel] [PATCH] ASoC: nau8824: user configuration of key detection
by John Hsu 17 Apr '18

The SAR ADC of key press detection varies depending on headset. We can't make a set of common threshold values for every case. Therefore, the driver provides configuration for user and they can set up values by UCM configuration.

[alsa-devel] [PATCH] ASoC: max98357a: Fix speaker pop when starting playback
by Ezequiel Garcia 16 Apr '18

16 Apr '18

From: Mac Chiang <mac.chiang(a)intel.com> Currently, speaker pop/crack noise can happen during PCM playback. This is due to the LRCLK being removed while the BCLK being present, which as per the datasheet can cause large DC output voltage. While on some platforms simply controlling the SD_MODE pin is enough to remove the noise, others have a significant delay between the BCLK and the LRCLK activation. Therefore, this commit adds a delay in the codec driver to guarantee clocks are both active by the time SD_MODE is asserted.
