ASoC: rt715: Make read-only arrays capture_reg_H and capture_reg_L static const

2022-12-05T14:05:41Z

Don't populate the read-only arrays capture_reg_H and capture_reg_L on the stack but instead make them static const. Also makes the object code a little smaller. Signed-off-by: Colin Ian King Link: https://lore.kernel.org/r/20221202171450.1815346-1-colin.i.king@gmail.com Signed-off-by: Mark Brown

ASoC: rt715: Switch to new snd_sdw_params_to_config helper

2022-11-28T13:04:31Z

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: codecs: soundwire: call pm_runtime_resume() in component probe

2022-06-17T17:37:59Z

Make sure that the bus and codecs are pm_runtime active when the card is registered/created. This avoid timeouts when accessing registers.

ASoC: rt715: Add endianness flag in snd_soc_component_driver

2022-05-09T11:46:47Z

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: rt*: Constify static struct snd_soc_dai_ops

2021-03-10T13:06:33Z

The only usage of them is to assign their address to the ops field in the snd_soc_dai_driver struct, which is a pointer to const. Make them const to allow the compiler to put them in read-only memory.
