From 9fe9efd6924c9a62ebb759025bb8927e398f51f7 Mon Sep 17 00:00:00 2001 From: Tomasz Figa Date: Wed, 14 Oct 2020 14:16:24 +0000 Subject: ASoC: Intel: kbl_rt5663_max98927: Fix kabylake_ssp_fixup function MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This is a copy of commit 5c5f1baee85a ("ASoC: Intel: kbl_rt5663_rt5514_max98927: Fix kabylake_ssp_fixup function") applied to the kbl_rt5663_max98927 board file. Original explanation of the change: kabylake_ssp_fixup function uses snd_soc_dpcm to identify the codecs DAIs. The HW parameters are changed based on the codec DAI of the stream. The earlier approach to get snd_soc_dpcm was using container_of() macro on snd_pcm_hw_params. The structures have been modified over time and snd_soc_dpcm does not have snd_pcm_hw_params as a reference but as a copy. This causes the current driver to crash when used. This patch changes the way snd_soc_dpcm is extracted. snd_soc_pcm_runtime holds 2 dpcm instances (one for playback and one for capture). 2 codecs on the SSP are dmic (capture) and speakers (playback). Based on the stream direction, snd_soc_dpcm is extracted from snd_soc_pcm_runtime.

On top of that, there is an equivalent set of configs targeting the same solution: - SND_SST_ATOM_HIFI2_PLATFORM (core) - SND_SST_ATOM_HIFI2_PLATFORM_PCI - SND_SST_ATOM_HIFI2_PLATFORM_ACPI As both sets do the same job - allow for granular platform selection - remove the duplicate set and rely on SND_SST_ATOM_HIFI2_PLATOFRM_XXX configs alone.

Reasons for such thing is partly because Qualcomm machine drivers never cared to set driver_name.

Otherwise the codec may produce some noise after the end of DAPM power down sequence. The delay between DAC and CLOCK_SUPPLY widgets is too short. Add a delay in mclk shutdown request to manage the shutdown delay explicitly. From experiments, at least 10ms delay is necessary. Set delay to 20ms as recommended in Documentation/timers/timers-howto.rst when using msleep().
