2019-10-09ASoC: jz4740: Remove unused match variableStephen Boyd
After commit 67ad656bdd70 ("ASoC: jz4740: Use of_device_get_match_data()"), the match local variable is unused and the compiler rightly warns. sound/soc/jz4740/jz4740-i2s.c: In function 'jz4740_i2s_dev_probe': sound/soc/jz4740/jz4740-i2s.c:500:29: warning: unused variable 'match' [-Wunused-variable] 500 | const struct of_device_id *match; Drop it.

Current snd_soc_component_driver has pcm_new/pcm_free, but, it doesn't have "component" at parameter. Thus, each callback can't know it is called for which component. Each callback currently is getting "component" by using snd_soc_rtdcom_lookup() with driver name. It works today, but, will not work in the future if we support multi CPU/Codec/Platform, because 1 rtd might have multiple same driver name component.

Thus, each callback can't know it is called for which component. Thus, each callback currently is getting "component" by using snd_soc_rtdcom_lookup() with driver name (3). --- ALSA SoC --- ... if (component->driver->ops && component->driver->ops->open) (1) return component->driver->ops->open(substream); ... --- driver --- (2) static int xxx_open(struct snd_pcm_substream *substream) { struct snd_soc_pcm_runtime *rtd = substream->private_data; (3) struct snd_soc_component *component = snd_soc_rtdcom_lookup(..); ... } It works today, but, will not work in the future if we support multi CPU/Codec/Platform, because 1 rtd might have multiple components which have same driver name. To solve this issue, each callback needs to be called with component. We already have many component driver callback. This patch copies each snd_pcm_ops member under component driver, and having "component" as parameter. --- ALSA SoC --- ... if (component->driver->open) => return component->driver->open(component, substream); ... --- driver --- => static int xxx_open(struct snd_soc_component *component, struct snd_pcm_substream *substream) { ... } *Note* Only Intel skl-pcm has .get_time_info implementation, but ALSA SoC framework doesn't call it so far.

2019-10-08ASoC: pcm3168a: Use fixup instead of constraint for channels and formatsPeter Ujfalusi
The snd_pcm_hw_constraint_minmax() works fine when a single codec is connected to a single CPU DAI, but in multicodec or DPCM setup the constraints placed by the driver will apply to the whole PCM stream (FE included) and thus prevents more than 8 playback channels for example.

2019-10-07ASoC: SOF: support alternate list of machinesPierre-Louis Bossart
For cases where an interface can be pin-muxed, we need to assess at probe time which configuration should be used. In cases such as SoundWire, we need to maintain an alternate list of machines and walk through them when the primary detection based on ACPI _HID fails.

2019-10-07ASoC: soc-acpi: add link_mask fieldPierre-Louis Bossart
When interfaces can be pin-muxed, static information from ACPI might not be enough. Add information on which links needs to be enabled by hardware/firmware for a specific machine driver to be selected. When walking through the list of possible machines, links will be checked, which implies that configurations where multiple links are required need to be checked first. Additional criteria will be needed later, such as which SoundWire Slave devices are actually enabled, but for now this helps detect between basic configurations.
