snd_pcm_ops is no longer needed. Let's use component driver callback. *Note* Only Intel skl-pcm has .get_time_info implementation, but ALSA SoC framework doesn't call it so far. To keep its implementation, this patch keeps .get_time_info, but it is still not called. Intel guy need to support it in the future. Signed-off-by:

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. To solve this issue, each callback need to be called with component. This patch adds new pcm_construct/pcm_destruct with "component" parameter. Signed-off-by:

Current snd_soc_component_driver has snd_pcm_ops, and each driver can have callback via it (1). But, it is mainly created for ALSA, thus, it doesn't have "component" as parameter for ALSA SoC (1)(2). 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.

Before regmap_reinit_cache we must reset audio regs as default values. So we use reset controller unit(toprgu) to reset audio hw. Signed-off-by:

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. Signed-off-by:

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. Signed-off-by:

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. Signed-off-by:

According the documentation for snd_soc_update_bits the API will return a 1 if the update was successful with a value change, a 0 if the update was successful with no value change or a negative if the command just failed. So the value of return in the driver needs to be checked for being less then 0 or the caller may indicate failure when the value actually changed. Signed-off-by:

There are several problems in the error handling in fsl_mqs_probe(). 1) "ret" isn't initialized on some paths. GCC has a feature which warns about uninitialized variables but the code initializes "ret" to zero at the start of the function so the checking is turned off. 2) "gpr_np" is a pointer so initializing it to zero is confusing and generates a Sparse warning. 3) of_parse_phandle() doesn't return error pointers on error, it returns NULL. 4) If devm_snd_soc_register_component() fails then the function should free the "gpr_np".

This probe function is only called if the device is backed by a DT node, so switch this call to of_device_get_match_data() to reduce code size and simplify a bit. This also avoids needing to reference a potentially undefined variable because of_device_get_match_data() doesn't need to know anything beyond the struct device to find the match table.

dai / component related resources are created when component is registered, and it will be freed when component was unregistered. These resources are not re-used after that. This means, we can use devm_xxx for dai / component, without thinking about kfree(). This patch uses devm_xxx for these. Signed-off-by:

It is easy to read code if it is cleanly using paired function/naming, like start <-> stop, register <-> unregister, etc, etc. But, current ALSA SoC code is very random, unbalance, not paired, etc. It is easy to create bug at the such code, and it will be difficult to debug. soc_cleanup_card_resources() (a) which is paired function of snd_soc_instantiate_card() (A) is calling soc_remove_dai_links() (*) to remove card related resources, but it is breaking add/remove balance (B)(b)(C)(c)(D)(d), in other words these should be called from soc_cleanup_card_resources() (a) from balance point of view. More headacke is that it is using original removing method for dai_link even though we already have snd_soc_remove_dai_link() which is the function for it (d). This patch removes snd_soc_remove_dai_links() and balance up code. static void soc_remove_dai_links(...) { ... (b) soc_remove_link_dais(card); (c) soc_remove_link_components(card); for_each_card_links_safe(card, link, _link) { ... /* it should use snd_soc_remove_dai_link() here */ (d) list_del(&link->list); } } (a) static int soc_cleanup_card_resources(...) { ... /* remove and free each DAI */ (*) soc_remove_dai_links(card); ... } (A) static int snd_soc_instantiate_card(struct snd_soc_card *card) { ... /* add predefined DAI links to the list */ for_each_card_prelinks(card, i, dai_link) (B) snd_soc_add_dai_link(card, dai_link); ... /* probe all components used by DAI links on this card */ (C) ret = soc_probe_link_components(card); ... /* probe all DAI links on this card */ (D) ret = soc_probe_link_dais(card); ... } Signed-off-by: -

Current rtd, rtd->dev, rtd->codec_dais are created by normal kzalloc(), but we want to use devm_kzalloc() as much as possible. Created rtd->dev is registered by device_register() at soc_new_pcm_runtime(), and it will be freed at soc_free_pcm_runtime() by device_unregister(). This means, if we can use devm_kzalloc(rtd->dev, xxx) for rtd / rtd->codec_dais, all these are automatically freed via soc_free_pcm_runtime(). This patch uses devm_kzalloc(rtd->dev, xxx) for rtd / rtd->codec_dais. Signed-off-by:
