ASoC: soc.h: convert asoc_xxx() to snd_soc_xxx()

[ Upstream commit 1d5a2b5dd0a8d2b2b535b5266699429dbd48e62f ]

ASoC is using 2 type of prefix (asoc_xxx() vs snd_soc_xxx()), but there
is no particular reason about that [1].
To reduce confusing, standarding these to snd_soc_xxx() is sensible.

This patch adds asoc_xxx() macro to keep compatible for a while.
It will be removed if all drivers were switched to new style.

ASoC: soc-card: Add storage for PCI SSID

[ Upstream commit 47f56e38a199bd45514b8e0142399cba4feeaf1a ]

of the soundcard.

ASoC: soc-card: Add storage for PCI SSID

[ Upstream commit 47f56e38a199bd45514b8e0142399cba4feeaf1a ]

Add members to struct snd_soc_card to store the PCI subsystem ID (SSID)
of the soundcard.

The PCI specification provides two registers to store a vendor-specific
SSID that can be read by drivers to uniquely identify a particular
"soundcard". This is defined in the PCI specification to distinguish
products that use the same silicon (and therefore have the same silicon
ID) so that product-specific differences can be applied.

PCI only defines 0xFFFF as an invalid value. 0x0000 is not defined as
invalid. So the usual pattern of zero-filling the struct and then
assuming a zero value unset will not work. A flag is included to
indicate when the SSID information has been filled in.

Unlike DMI information, which has a free-format entirely up to the vendor,
the PCI SSID has a strictly defined format and a registry of vendor IDs.

It is usual in Windows drivers that the SSID is used as the sole identifier
of the specific end-product and the Windows driver contains tables mapping
that to information about the hardware setup, rather than using ACPI
properties.

This SSID is important information for ASoC components that need to apply
hardware-specific configuration on PCI-based systems.

As the SSID is a generic part of the PCI specification and is treated as
identifying the "soundcard", it is reasonable to include this information
in struct snd_soc_card, instead of components inventing their own custom
ways to pass this information around.

Merge tag 'sound-6.6-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound

Pull sound updates from Takashi Iwai:
"We've received a fairly wide range of changes at this time, including
for ALSA and ASoC core, but all of them are rather small changes.

Here are some highlights:

ALSA / ASoC Core:
- Fixes of inconsistent locking around control API helpers
- A few new control API functions and cleanups
- Workarounds for potential UAFs by delayed kobj releases
- Unified PCM copy ops with iov_iter
- Continued efforts for ASoC API cleanups

ASoC:
- An adaptor to allow use of IIO DACs and ADCs in ASoC which pulls in
some IIO changes
- Create a library function for intlog10() and use it in the NAU8825
driver
- Convert drivers to use the more modern maple tree register cache
- Lots of work on the SOF framework, AMD and Intel drivers, including
a lot of cleanup and new device support
- Standardization of the presentation of jacks from drivers
- Provision of some generic sound card DT properties
- Support for AMD Van Gogh, AMD machines with MAX98388 and NAU8821,
AWInic AW88261, Cirrus Logic CS35L36 and CS42L43, various Intel
platforms including AVS machines with ES8336 and RT5663, Mediatek
MT7986, NXP i.MX93, RealTek RT1017 and StarFive JH7110

Others:
- New test coverage including ASoC and topology tests in KUnit; this
also involves enabling UML builds of ALSA since that's the default
KUnit test environment which pulls in the addition of some stubs to
the driver
- More enhancement of pcmtest driver
- A few fixes / enhancements of MIDI 2.0 UMP core
- Using PCI definitions in allover HD-audio code
- Support for Cirrus CS35L56 and TI TAS2781 HD-audio sub-codecs
- CS35L41 HD-audio sub-codec improvements
- Continued emu10k1 improvements"

ASoC: Updates for v6.6

Here's an initial batch of updates for ASoC for this release cycle.
We've got a bunch of new drivers in here, a bit of core work from
Morimoto-san and quite a lot of janitorial work. There's several
updates that pull in changes from other subsystems in order to build
on them:

- An adaptor to allow use of IIO DACs and ADCs in ASoC which pulls in
some IIO changes.
- Create a library function for intlog10() and use it in the NAU8825
driver.
- Include the ASoC tests, including the topology tests, in the default
KUnit full test coverage. This also involves enabling UML builds of
ALSA since that's the default KUnit test environment which pulls in
the addition of some stubs to the driver.
- More factoring out from Morimoto-san.
- Convert a lot of drivers to use the more modern maple tree register
cache.
- Support for AMD machines with MAX98388 and NAU8821, Cirrus Logic
CS35L36, Intel AVS machines with ES8336 and RT5663 and NXP i.MX93.

ASoC: soc-core.c: enable multi Component

ASoC: soc-core.c: enable multi Component

Current ASoC Card is using dlc (snd_soc_dai_link_component) to find
target DAI / Component to be used.
Current dlc has below 3 items to identify DAI / Component

(a) name for Component
(b) of_node for Component
(c) dai_name for DAI

(a) or (b) is used to identify target Component, and (c) is used
to identify DAI.

One of the biggest issue on it today is dlc needs "name matching"
for "dai_name" (c).

It was not a big deal when we were using platform_device, because we
could specify nessesary "dai_name" via its platform_data.

But we need to find DAI name pointer from whole registered datas and/or
each related driver somehow in case of DT, because we can't specify it.
Therefore, Card driver parses DT and assumes the DAI, and find its name
pointer. How to assume is based on each Component and/or Card.

Next biggest issue is Component node (a)/(b).

Basically, Component is registered when CPU/Codec driver was
probed() (X). Here, 1 Component is possible to have some DAIs.

int xxx_probe(struct platform_device *pdev)
{
...
(X) ret = devm_snd_soc_register_component(pdev->dev,
&component_driver,
&dai_driver, dai_driver_num);
...
}

The image of each data will be like below.
One note here is "driver" is included for later explanation.

+-driver------+
|+-component-+|
|| dai0||
|| dai1||
|| ...||
|+-----------+|
+-------------+

The point here is 1 driver has 1 Component, because basically driver
calles snd_soc_register_component() (= X) once.

Here is the very basic CPU/Codec connection image.

HW image SW image
+-- Board ------------+ +-card--------------------------+
|+-----+ +------+| |+-driver------+ +-driver------+|
|| CPU | <--> |CodecA|| ||+-component-+| |+-component-+||
|+-----+ +------+| ||| dai|<=>|dai |||
+---------------------+ ||+-----------+| |+-----------+||
|+-------------+ +-------------+|
+-------------------------------+

It will be very complex if it has multi DAIs.
Here is intuitive easy to understandable HW / SW example.

HW image SW image
+-- Board ---------------+ +-card--------------------------+
|+--------+ +------+| |+-driver------+ +-driver------+|
|| CPU ch0| <--> |CodecA|| ||+-component-+| |+-component-+||

+------------------------+ ||| || |+-component-+||
||| ch1 dai|<=>|dai |||
||+-----------+| |+-----------+||
|+-------------+ +-------------+|
+-------------------------------+

It will be handled as multi interface as "one Card".

card0,0: CPU-ch0 - CodecA
card0,1: CPU-ch1 - CodecB
^

But, here is the HW image example which will be more complex

+-- Basic Board ---------+
|+--------+ +------+|
|| CPU ch0| <--> |CodecA||
|| ch1| <-+ +------+|
|+--------+ | |
+-------------|----------+
+-- expansion board -----+
| | +------+|
| +->|CodecB||
| +------+|
+------------------------+

We intuitively think we want to handle these as "2 Sound Cards".

card0,0: CPU-ch0 - CodecA
card1,0: CPU-ch1 - CodecB
^

But below image which we can register today doesn't allow it,
because the same Component will be connected to both Card0/1,
but it will be rejected by (Z).

if (component->card) {
(Z) if (component->card != card) {

So, how about to call snd_soc_register_component() (= X) multiple times
on probe() to avoid buplicated component->card limitation, to be like
below ?

Yes, looks good. But unfortunately it doesn't help us for now.
Let's see soc_component_to_node() and snd_soc_is_matching_component()

static struct device_node
*soc_component_to_node(struct snd_soc_component *component)
{
...
(A) of_node = component->dev->of_node;
...
}

static int snd_soc_is_matching_component(...)
{
...
(B) if (dlc->of_node && component_of_node != dlc->of_node)
...
}

dlc checkes "of_node" to identify target component (B),
but this "of_node" came from component->dev (A) which is added
by snd_soc_register_component() (X) on probe().

This means we can have different "component->card", but have same
"component->dev" in this case.

Even though we calls snd_soc_register_component() (= X) multiple times,
all Components have same driver's dev, thus it is impossible to
identified the Component.
And if it was impossible to identify Component, it is impossible to
identify DAI on current implementation.

So, how to handle above complex HW image today is 2 patterns.
One is handles it as "1 big sound card".
The SW image is like below.

SW image
+-card--------------------------+
|+-driver------+ +-driver------+|
||+-component-+| |+-component-+||
||| ch0 dai|<=>|dai |||
||| || |+-----------+||
||| || +-------------+|
||| || +-driver------+|
||| || |+-component-+||
||| ch1 dai|<->|dai |||
||+-----------+| |+-----------+||
|+-------------+ +-------------+|
+-------------------------------+

But the problem is not intuitive.
We want to handle it as "2 Cards".

2nd pattern is like below.

SW image
+-card0-------------------------+
|+-driver------+ +-driver------+|
||+-component-+| |+-component-+||
||| ch0 dai|<=>|dai |||
||+-----------+| |+-----------+||
|+-------------+ +-------------+|
+-------------------------------+

+-card1-------------------------+
|+-driver------+ +-driver------+|
||+-component-+| |+-component-+||
||| ch1 dai|<=>|dai |||
||+-----------+| |+-----------+||
|+-------------+ +-------------+|
+-------------------------------+

It handles as "2 Cards", but CPU part needs to be probed as 2 drivers.
It is also not intuitive.

To solve this issue, we need to have multi Component support.

In current implementation, we need to identify Component first
to identify DAI, and it is using name matching to identify DAI.

But how about to be enable to directly identify DAI by unique way
instead of name matching ? In such case, we can directly identify DAI,
then it can identify Component from DAI.

For example Simple-Card / Audio-Graph-Card case, it is specifying DAI
via its node.

Simple-Card

sound-dai = <&cpu-sound>;

Audio-Graph-Card

dais = <&cpu-sound>;

If each CPU/Codec driver keeps this property when probing,
we can identify DAI directly from Card.
Being able to identify DAI directly means being able to identify its
Component as well even though Component has same dev (= B).

This patch adds new "dai_node" for it.

To keeping compatibility, it checks "dai_node" first if it has,
otherwise, use existing method (name matching).

Merge tag 'sound-6.5-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound

Pull sound updates from Takashi Iwai:
"Lots of changes as usual, but the only significant stuff in ALSA core
part is the MIDI 2.0 support, while ASoC core kept receiving the code
refactoring. The majority of changes are seen rather in device
drivers, and quite a few new drivers can be found there.

Here we go, some highlights:

ALSA and ASoC Core:
- Support of MIDI 2.0 devices: rawmidi and sequencer API have been
extended for the support of the new UMP (Universal MIDI Packet)
protocol, USB audio driver got the USB MIDI 2.0 interface support
- Continued refactoring around ASoC DAI links and the ordering of
trigger callbacks
- PCM ABI extension for better drain support

ASoC Drivers:
- Conversions of many drivers to use maple tree based caches
- Everlasting improvement works on ASoC Intel drivers
- Compressed audio support for Qualcomm
- Support for AMD SoundWire, Analog Devices SSM3515, Google
Chameleon, Ingenic X1000, Intel systems with various CODECs,
Loongson platforms, Maxim MAX98388, Mediatek MT8188, Nuvoton
NAU8825C, NXP platforms with NAU8822, Qualcomm WSA884x, StarFive
JH7110, Texas Instruments TAS2781

HD-audio:
- Quirks for HP and ASUS machines
- CS35L41 HD-audio codec fixes
- Loongson HD-audio support

Misc:
- A new virtual PCM test driver for kselftests
- Continued refactoring and improvements on the legacy emu10k1
driver"
