ASoC: soc-core.c: add index on snd_soc_of_get_dai_name()

2023-06-20T11:49:22+00:00

Current snd_soc_of_get_dai_name() doesn't accept index
for #sound-dai-cells. It is not useful for user.
This patch adds it.

ASoC: soc-core.c: add snd_soc_{of_}get_dlc()

2023-06-20T11:49:21+00:00

Current soc-core.c has snd_soc_{of_}get_dai_name() to get DAI name
for dlc (snd_soc_dai_link_component). It gets .dai_name, but we need
.of_node too. Therefor user need to arrange.

It will be more useful if it gets both .dai_name and .of_node.
This patch adds snd_soc_{of_}get_dlc() for it, and existing functions
uses it.

Merge series from Kuninori Morimoto :

This patch-set adds new "trigger" starting/stopping method.

ASoC: remove old trigger ordering method

2023-06-13T11:11:23+00:00

All drivers switch to use generic trigger ordering method.
Let's remove old method.

ASoC: add new trigger ordering method

2023-06-13T11:11:19+00:00

Current ASoC is assuming that trigger starting order is
Link -> Component -> DAI as default, and its reverse order for stopping.
But some Driver / Card want to reorder it for some reasons.
We have such flags, but is unbalance like below.

	struct snd_soc_component_driver	:: start_dma_last
	struct snd_soc_dai_link		:: stop_dma_first

We want to have more flexible, and more generic method.
This patch adds new snd_soc_trigger_order for start/stop at
component / DAI-link.

ASoC: add N cpus to M codecs dai link support

2023-06-13T11:11:15+00:00

Currently, ASoC supports dailinks with the following mappings:
1 cpu DAI to N codec DAIs
N cpu DAIs to N codec DAIs
But the mapping between N cpu DAIs and M codec DAIs is not supported.
The reason is that we didn't have a mechanism to map cpu and codec DAIs

This patch suggests a new snd_soc_dai_link_codec_ch_map struct in
struct snd_soc_dai_link{} which provides codec DAI to cpu DAI mapping
information used to implement N cpu DAIs to M codec DAIs
support.

When a dailink contains two or more cpu DAIs, we should set channel
number of cpus based on its channel mask. The new struct also provides
channel mask information for each codec and we can construct the cpu
channel mask by combining all codec channel masks which map to the cpu.

The N:M mapping is however restricted to the N <= M case due to physical
restrictions on a time-multiplexed bus such as I2S/TDM, AC97, SoundWire
and HDaudio.

ASoC: add snd_soc_get_stream_cpu()

2023-06-06T15:57:31+00:00

We are using get_stream_cpu() to get CPU stream which cares
Codec2Codec. But it is static function for now, and we want to use it
from other files. This patch makes it global function.

ASoC: expand snd_soc_dpcm_mutex_lock/unlock()

2023-04-17T11:57:25+00:00

soc-pcm.c has snd_soc_dpcm_mutex_lock/unlock(),
but other files can't use it because it is static function.

It requests snd_soc_pcm_runtime as parameter (A), but sometimes we
want to use it by snd_soc_card (B).

(A)	static inline void snd_soc_dpcm_mutex_lock(struct snd_soc_pcm_runtime *rtd)
	{
		mutex_lock_nested(&rtd->card->pcm_mutex, rtd->card->pcm_subclass);
	}			   ^^^^^^^^^

(B)	mutex_lock_nested(&card->pcm_mutex, card->pcm_subclass);
			   ^^^^

We want to use it with both "rtd" and "card" for dapm lock/unlock.
To enable it, this patch uses _Generic macro.

This patch makes snd_soc_dpcm_mutex_{un}lock() global function, and use it on
each files.
