7fba6aea44 ALSA: hda: Rename back to dmic_detect option
We've got quite a few bug reports showing the SOF driver being loaded
unintentionally recently, and the reason seems to be that users didn't
know the module option change: with the recent kernel, a new option
dsp_driver=1 has to be passed to a new module snd-intel-dspcfg
instead of snd_hda_intel.dmic_detect=0 option.

That is, actually there are two tricky things here:
- We changed the whole detection in another module and another
  option semantics.
- The existing option for skipping the DSP probe was also renamed.

For avoiding the confusion and giving user more hint, this patch
reverts the renamed option dsp_driver back to dmic_detect for
snd-hda-intel module, and show the warning about the module option
change when the non-default value is passed.

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 duplicate pinctrl operation when suspend

		for_each_card_rtds(card, rtd) {
			...
(2)			pinctrl_pm_select_sleep_state(cpu_dai->dev);
		}
	}

(1) is called for all component (CPU/Codec/Platform), and
(2) is called for CPU DAIs.
Here, component->dev is same as dai->dev.
This means, it is called in duplicate on CPU case.
This patch removes (2).

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);
			...
(a)			snd_soc_rtdcom_add(rtd, rtd->codec_dais[i]->component);
		}
		...

		/* Find PLATFORM from registered PLATFORMs */
(b)		for_each_link_platforms(dai_link, i, platform) {
			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: stm32: sai: fix possible circular locking
In current driver, locks can be taken as follows:
- Register access: take a lock on regmap config and then on clock.
- Master clock provider: take a lock on clock and then on regmap config.
This can lead to the circular locking summarized below.

Remove peripheral clock management through regmap framework, and manage
peripheral clock in driver instead. On register access, lock on clock
is taken first, which allows to avoid possible locking issue.

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:

Commit 62d5ae4cafb7 ("ASoC: max98090: save and restore SHDN when changing

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.

When an ASoC driver with pcm_destruct component ops is freed before

unconditionally.

Fix it by adding a NULL-check of rtd->pcm before calling callbacks.

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.
