2022-05-09ASoC: wcd938x: Add endianness flag in snd_soc_component_driverCharles Keepax
The endianness flag is used on the CODEC side to specify an ambivalence to endian, typically because it is lost over the hardware link. This device receives audio over a SoundWire DAI and as such should have endianness applied.

https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound into for-linus ASoC: Updates for v5.18 Quite a quiet release for ASoC, lots of work on drivers and platforms but nothing too groundbreaking but not much on the core itself: - Start of moving SoF to support multiple IPC mechanisms. - Use of NHLT ACPI table to reduce the amount of quirking required for Intel systems. - Some building blocks for use in forthcoming Intel AVS driver for legacy Intel DSP firmwares. - Support for AMD PDM, Atmel PDMC, Awinic AW8738, i.MX cards with TLV320AIC31xx, Intel machines with CS35L41 and ESSX8336, Mediatek MT8181 wideband bluetooth, nVidia Tegra234, Qualcomm SC7280, Renesas RZ/V2L, Texas Instruments TAS585M

2021-12-24ASoC/SoundWire: dai: expand 'stream' concept beyond SoundWirePierre-Louis Bossart
The HDAudio ASoC support relies on the set_tdm_slots() helper to store the HDaudio stream tag in the tx_mask. This only works because of the pre-existing order in soc-pcm.c, where the hw_params() is handled for codec_dais *before* cpu_dais. When the order is reversed, the stream_tag is used as a mask in the codec fixup functions: /* fixup params based on TDM slot masks */ if (substream->stream == SNDRV_PCM_STREAM_PLAYBACK && codec_dai->tx_mask) soc_pcm_codec_params_fixup(&codec_params, codec_dai->tx_mask); As a result of this confusion, the codec_params_fixup() ends-up generating bad channel masks, depending on what stream_tag was allocated. We could add a flag to state that the tx_mask is really not a mask, but it would be quite ugly to persist in overloading concepts. Instead, this patch suggests a more generic get/set 'stream' API based on the existing model for SoundWire. We can expand the concept to store 'stream' opaque information that is specific to different DAI types. In the case of HDAudio DAIs, we only need to store a stream tag as an unsigned char pointer. The TDM rx_ and tx_masks should really only be used to store masks. Rename get_sdw_stream/set_sdw_stream callbacks and helpers as get_stream/set_stream. No functionality change beyond the rename.

Interrupt Clear registers WCD938X_INTR_CLEAR_0 - WCD938X_INTR_CLEAR_2 are not marked as volatile. This has resulted in a missing interrupt bug while performing runtime pm. regcache_sync() during runtime pm resume path will write to Interrupt clear registers with previous values which basically clears the pending interrupt and actual interrupt handler never sees this interrupt. This issue is more visible with headset plug-in plug-out case compared to headset button.
