ASoC: soc-acpi: add _ADR-based link descriptors

For SoundWire support, we added a 'link_mask' to describe the PCB hardware
layout. This helped form a signature that can be used as a first-order way
of detecting the hardware and selecting the machine driver.

The concept of link_mask is however not enough. Some BIOS enable all links,
even when there are no devices physically connected. We can also see
variations with multiple devices attached on one link, or different types
of devices connected on the same link. To accurately represent the
hardware, we need to build static tables where each link exposes a list of
expected devices represented by the 64-bit _ADR field (which uniquely
identifies each device).

The new 'links' field is optional when the link_mask is sufficient to
represent a platform in a unique way.

The existing mechanism to support I2C devices is left as is, it'd be too
invasive to change the existing support for _HID and the notion of link is
not relevant either.

ASoC: SOF: fix PCM playback through ALSA OSS emulation

Any app using ALSA OSS emulation on top of SOF will fail
to error from OSS SNDCTL_DSP_SETFMT ioctl. Reported initially
as an issue with xournalpp (application using PortAudio with
an OSS backend), but applies more generally to other apps
using OSS as well.

Problem is caused by SOF PCM not supporting repeated calls
to hw_params(), without matching calls to pcm_free(). This
is however exactly what the ALSA OSS PCM code is doing when
it is handling the OSS ioctls.

The problem will lead to leaking of DSP resources and eventual
failure of DSP PCM_PARAMS IPC.

ASoC: soc-core: do pinctrl_pm_select_xxx() as component

ALSA SoC need to care pinctrl_pm_select_xxx().
It is called at soc-core and soc-pcm.
soc-pcm  is controlling it for activate DAI.
soc-core is controlling it for whole system
(= suspend/resume/probe/poweroff).

If we focus to soc-core side, it need to care about BIAS level.
Then, snd_soc_suspend() only is controlling it by Component base (a).
Other functions are DAI base (b).

(a) pinctrl_pm_select_xxx(component->dev, xxx);
(b) pinctrl_pm_select_xxx(dai->dev, xxx);

Because of these unbalance, the code is confusable.
Here, dai->dev and component->dev are same pointer.
Thus, we can replace it component base.

One note here is that it cared DAI (= CPU/Codec) pin before this patch,
after this patch, it cares Component (= CPU/Codec/Platform) pin.

ASoC: soc-core: remove snd_soc_rtdcom_list

Current ALSA SoC is using struct snd_soc_rtdcom_list to
connecting component to rtd by using list_head.

struct snd_soc_rtdcom_list {
struct snd_soc_component *component;
struct list_head list; /* rtd::component_list */
};

struct snd_soc_pcm_runtime {
...
struct list_head component_list; /* list of connected components */
...
};

The CPU/Codec/Platform component which will be connected to rtd (a)
is indicated via dai_link at snd_soc_add_pcm_runtime()

int snd_soc_add_pcm_runtime(...)
{
...
/* Find CPU from registered CPUs */
rtd->cpu_dai = snd_soc_find_dai(dai_link->cpus);
...
(a) snd_soc_rtdcom_add(rtd, rtd->cpu_dai->component);
...

/* Find CODEC from registered CODECs */
(b) for_each_link_codecs(dai_link, i, codec) {
rtd->codec_dais[i] = snd_soc_find_dai(codec);
...

}

for_each_component(component) {
...
(a) snd_soc_rtdcom_add(rtd, component);
}
}

}

It shows, it is possible to know how many components will be
connected to rtd by using

dai_link->num_cpus
dai_link->num_codecs
dai_link->num_platforms

If so, we can use component pointer array instead of list_head,
in such case, code can be more simple.
This patch removes struct snd_soc_rtdcom_list that is only
of temporary value, and convert to pointer array.

ASoC: max98090: fix lockdep warning

Commit 62d5ae4cafb7 ("ASoC: max98090: save and restore SHDN when changing
sensitive registers") extended the code for handling many controls by
adding a custom put function to them. That new custom put function
properly handles relations between codec's hardware registers. However
they used card->dapm_mutex to properly serialize those operations. This
in turn triggers a lockdep warning about possible circular dependency.
Fix this by introducing a separate mutex only for serializing the SHDN
hardware register related operations.

This fixes the following lockdep warning observed on Exynos4412-based
Odroid U3 board:

ASoC: SOF: pci: change the default firmware path when the community key is used

Since ApolloLake, Intel platforms require signed firmware. On all
Windows platforms the default is to require the Intel production key
be used. But some platforms allow for a community key to be used,
which allows developers to compile/build their own firmware.

In the linux-firmware tree, the default intel/sof path is used for
firmwares signed for the production key, and files signed with the
community key are located in intel/sof/community.

Since we don't have an API to query which key is used on what
platforms, we have to rely on DMI-based quirks.

Developers can bypass this mechanism by setting a kernel 'fw_path'
module parameter. Additional dynamic debug traces are provided to help
debug cases where the wrong file might be used.

ASoC: Intel: sof_rt5682: Ignore the speaker amp when there isn't one.

Some members of the Google_Hatch family include a rt5682 jack codec, but
no speaker amplifier. This uses the same driver (sof_rt5682) as a
combination of rt5682 jack codec and max98357a speaker amplifier. Within
the sof_rt5682 driver, these cases are not currently distinguishable,
relying on a DMI quirk to decide the configuration. This causes an
incorrect configuration when only the rt5682 is present on a
Google_Hatch device.

For CML, the jack codec is used as the primary key when matching,
with a possible speaker amplifier described in quirk_data. The two cases
of interest are the second and third 10EC5682 entries in
snd_soc_acpi_intel_cml_machines[]. The second entry matches the
combination of rt5682 and max98357a, resulting in the quirk_data field
in the snd_soc_acpi_mach being non-null, pointing at
max98357a_spk_codecs, the snd_soc_acpi_codecs for the matched speaker
amplifier. The third entry matches just the rt5682, resulting in a null
quirk_data.

The sof_rt5682 driver's DMI data matching identifies that a speaker
amplifier is present for all Google_Hatch family devices. Detect cases
where there is no speaker amplifier by checking for a null quirk_data in
the snd_soc_acpi_mach and remove the speaker amplifier bit in that case.

ASoC: SOF: imx8: Fix dsp_box offset

dsp_box is used to keep DSP initiated messages. The value of dsp_offset
is set by the DSP with the first message, so we need a way to bootstrap
it in order to get the first message.

We do this by setting the correct default dsp_box offset which on i.MX8
is not zero.

Very interesting is why it has worked until now.

On i.MX8, DSP communicates with ARM core using a shared SDRAM memory
area. Actually, there are two shared areas:
* SDRAM0 - starting at 0x92400000, size 0x800000
* SDRAM1 - starting at 0x92C00000, size 0x800000

SDRAM0 keeps the data sections, starting with .rodata. By chance
fw_ready structure was placed at the beginning of .rodata.

dsp_box_base is defined as SDRAM0 + dsp_box_offset and it is placed
at the beginning of SDRAM1 (dsp_box_offset should be 0x800000). But
because it is zero initialized by default it points to SDRAM0 where
by chance the fw_ready was placed in the SOF firmware.

Anyhow, SOF commit 7466bee378dd811b ("clk: make freq arrays constant")
fw_ready is no longer at the beginning of SDRAM0 and everything shows
how lucky we were until now.

Fix this by properly setting the default dsp_box offset.

ASoC: meson: axg-fifo: fix fifo threshold setup

On TODDR sm1, the fifo threshold register field is slightly different
compared to the other SoCs. This leads to the fifo A being flushed to
memory every 8kB. If the period is smaller than that, several periods
are pushed to memory and notified at once. This is not ideal.

Fix the register field update. With this, the fifos are flushed every
128B. We could still do better, like adapt the threshold depending on
the period size, but at least it consistent across the different

ASoC: SOF: Intel: drop HDA codec upon probe failure

In case a HDA codec probe fails, do not raise error immediately,
but instead remove the codec from bus->codec_mask and continue
probe for other codecs.

This allows for more robust behaviour in cases where one codec
in the system is faulty. SOF driver load can still proceed with
the codecs that can be probed successfully. Probe may still

ASoC: SOF: Introduce state machine for FW boot

Add a state machine for FW boot to track the
different stages of FW boot and replace the boot_complete
field with fw_state field in struct snd_sof_dev.
This will be used to determine the actions to be performed
during system suspend.

One of the main motivations for adding this change is the
fact that errors during the top-level SOF device probe cannot
be propagated and therefore suspending the SOF device normally
during system suspend could potentially run into errors.
For example, with the current flow, if the FW boot failed
for some reason and the system suspends, the SOF device
suspend could fail because the CTX_SAVE IPC would be attempted
even though the FW never really booted successfully causing it
to time out. Another scenario that the state machine fixes
is when the runtime suspend for the SOF device fails and
the DSP is powered down nevertheless, the CTX_SAVE IPC during
system suspend would timeout because the DSP is already
powered down.
