ASoC: codecs: constify static sdw_slave_ops struct

2023-05-17T11:58:39Z

[ Upstream commit 65b7b869da9bd3bd0b9fa60e6fe557bfbc0a75e8 ] The struct sdw_slave_ops is not modified and sdw_driver takes pointer to const, so make it a const for code safety.

ASoC: rt1316-sdw: Switch to new snd_sdw_params_to_config helper

2022-11-28T13:04:27Z

The conversion from hw_params to SoundWire config is pretty standard as such most of the conversion can be handled by the new snd_sdw_params_to_config helper function.

ASoC: rt1316-sdw: get BQ params property and apply them

2022-11-10T20:42:22Z

If the machine driver level sets the BQ params into the device property, the codec driver will get the BQ params and apply them.

ASoC: rt1316-sdw: Add endianness flag in snd_soc_component_driver

2022-05-09T11:46:50Z

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.

ASoC/SoundWire: dai: expand 'stream' concept beyond SoundWire

2021-12-24T14:06:47Z

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.

ASoC: rt1316-sdw: use first_hw_init flag on resume

2021-06-08T12:36:30Z

The intent of the status check on resume was to verify if a SoundWire peripheral reported ATTACHED before waiting for the initialization to complete. This is required to avoid timeouts that will happen with 'ghost' devices that are exposed in the platform firmware but are not populated in hardware. Unfortunately we used 'hw_init' instead of 'first_hw_init'. Due to another error, the resume operation never timed out, but the volume settings were not properly restored.
