ASoC: Fixes for v7.2

We've got a good collection of device specific fix here, plus a couple
of stand out things:

 - Richard fixed some special cases with the new device_link creation
   by more gracefully handling any errors during creation.
 - Charles did some light refactoring of the SoundWire interfaces to
   fix some persistent randconfig issues that people kept running into.

ASoC: tas2781: Update default register address to TAS2563

2026-06-25T13:19:11+00:00

The previous TAS2781 address is overwritten during calibration,
so switching to the TAS2563 address is required.

ASoC: soc-core: Don't fail if device_link could not be created

2026-06-24T12:01:38+00:00

If device_link_add() fails in snd_soc_bind_card() just skip that
driver pair and carry on.

This means that ASoC must now keep track of which components it was
able to device_link to the card->dev. The new card_device_link member
of struct snd_soc_component is non-NULL if a device_link exists.

The intent of the device link is to ensure that the machine driver
system-suspends before the component drivers, to prevent ASoC
suspend attempting to reconfigure a driver that has already suspended.

It isn't possible to create this device link if the machine driver is
a parent of the component driver or already has a device_link in the
opposite direction. In this case skip the link. A warn is placed in
kernel log since this might indicate a genuine design problem with
those two drivers (this can be downgraded to dbg in future when
people are happy that all these special drivers correctly handle their
reversed shutdown order).

ASoC: Updates for v7.2

There's been quite a lot of framework improvements this time around,
though mainly cleanups and robustness rather than user visible features.
The same pattern is seen with a lot of the driver work that's going on,
there are new features but a huge proportion of this is bug fixing and
cleanup work.  We also have a good selectio of new device support.

 - Improvements to SDCA jack handling from Charles Keepax.
 - Use of device links to make suspend handling more robust from Richard
   Fitzgerald.
 - Use of a new helper to factor out a common pattern in SoundWire
   enmeration from Charles Keepax.
 - Slimming down of the component from Kuninori Morimoto.
 - Simplification of format auto selection from Kuninori Morimoto.
 - Lots of conversions to guard() from Bui Duc Phuc.
 - Addition of a simple-amplifier driver supporting more featureful GPIO
   controller amplifiers than the previous basic driver from Herve
   Codina.
 - Support for AMD ACP 7.x, Cirrus Logic CS42448/CS42888, Everest Semi
   ES9356, Mediatek MT2701 and MT8196, Renesas RZ/G3E, Spacemit K3,
   Texas Instruments TAC5xx2 and TAS67524.

ASoC: update auto format selection method

2026-06-12T17:57:58+00:00

Current DAI supports auto format selection. It allow to have array like
below.

(X)	static u64 xxx_auto_formats[] = {
(A)		/* First Priority */
		SND_SOC_POSSIBLE_DAIFMT_I2S	|
		SND_SOC_POSSIBLE_DAIFMT_LEFT_J,

		/* Second Priority */
(B)		SND_SOC_POSSIBLE_DAIFMT_DSP_A	|
		SND_SOC_POSSIBLE_DAIFMT_DSP_B,
	};

It try to find available format from I2S/LEFT_J first (A).
Then, try to find from I2S/LEFT_J/DSP_A/DSP_B if couldn't find (A)+(B).
(OR:ed)

In this method, it can't handle if there is format combination.
For example, some driver has pattern.

Pattern1
	I2S/RIFHT_J/LEFT_J (FORMAT) and NB_NF/IB_IF/IB_NF/NB_IF (INV)_
Pattern2
	DSP_A/DSP_B        (FORMAT) and NB_NF/      IB_NF

Because it will try to OR Pattern1 and Pattern2, un-supported
pattern might be selected.

This patch update method not to use OR, and assumes full format array.
Above sample (X) need to be

	static u64 xxx_auto_formats[] = {
		/* First Priority */
		SND_SOC_POSSIBLE_DAIFMT_I2S	|
		SND_SOC_POSSIBLE_DAIFMT_LEFT_J,

		/* Second Priority */
		SND_SOC_POSSIBLE_DAIFMT_I2S	|
		SND_SOC_POSSIBLE_DAIFMT_LEFT_J	|
		SND_SOC_POSSIBLE_DAIFMT_DSP_A	|
		SND_SOC_POSSIBLE_DAIFMT_DSP_B,
	};

Note: It doesn't support Multi CPU/Codec for now

Clock provider / consumer selection is based on board, we can't select
automatically from software. Let's remove SND_SOC_POSSIBLE_xBx_xFx.

ALSA: hda: Use the new helper for PCM instance refcount

2026-06-11T07:34:09+00:00

HD-audio core driver has some open-code for managing the refcount for

ALSA: Add simple refcount helper functions

2026-06-11T07:34:09+00:00

There are many open-code to manage the same pattern for refcount +
wakeup sync at closing.  Let's provide the common helper functions to
replace the open-code.

- The recount is kept in struct snd_refcount, where it's initialized
by snd_refcount_init().
- The user can simply reference or unreference via snd_refcount_get()
and snd_refcount_put() functions
- The user can wait for the all usages gone by snd_refcount_sync()

Note that here we use atomic_t instead of refcount_t since the current
users allow reusing the refcount after sync again.  The design of
refcount_t prevents exactly this behavior, so it doesn't fit.

ASoC: remove .debugfs_prefix from Component

2026-06-10T11:21:16+00:00

Kuninori Morimoto  says:

Basically, we are assuming to use snd_soc_register_component() (X) to
register Component. It requests Component driver (A).

And, current Component has .debugfs_prefix (B).

Now we can set component->debugfs_prefix (B) via
component_driver->debugfs_prefix (A) today.

But some drivers are still trying to set it via (B).
Thus, they need to use snd_soc_component_initialize() (1) /
snd_soc_component_add() (2) instead of (X), because they need to
access component->debugfs_prefix (B).

These functions (= 1, 2) should be capsuled into soc-xxx.c, but can't
because of above drivers.

This patch-set removes component->debugfs_prefix (B).

The functions (= 1, 2) are still not yet be capsuled.
This is step1 for it, step2 will be posted after this.
