ASoC: Updates for v5.10

Not a huge amount going on in the core for ASoC this time but quite a
lot of driver activity, especially for the Intel platforms:

 - Replacement of the DSP driver for some older x86 systems with a new
   one which was written with closer reference to the DSP firmware so
   should hopefully be more robust and maintainable.
 - A big batch of static checker and other fixes for the rest of the x86
   DSP drivers.
 - Cleanup of the error unwinding code from Morimoto-san, hopefully
   making it more robust.
 - Helpers for parsing auxiluary devices from the device tree from
   Stephan Gerhold.
 - New support for AllWinner A64, Cirrus Logic CS4234, Mediatek MT6359
   Microchip S/PDIF TX and RX controllers, Realtek RT1015P, and Texas
   Instruments J721E, TAS2110, TAS2564 and TAS2764

<title>ALSA: hda: fix jack detection with Realtek codecs when in D3</title>

<id>a6e7d0a4bdb02a7a3ffe0b44aaa8842b7efdd056</id>
<content type='text'>
In case HDA controller becomes active, but codec is runtime suspended,
jack detection is not successful and no interrupt is raised. This has
been observed with multiple Realtek codecs and HDA controllers from
different vendors. Bug does not occur if both codec and controller are
active, or both are in suspend. Bug can be easily hit on desktop systems
with no built-in speaker.

The problem can be fixed by powering up the codec once after every
controller runtime resume. Even if codec goes back to suspend later, the
jack detection will continue to work. Add a flag to 'hda_codec' to
describe codecs that require this flow from the controller driver.
Modify __azx_runtime_resume() to use pm_request_resume() to make the
intent clearer.

Mark all Realtek codecs with the new forced_resume flag.

soc_pcm_open() does rollback when failed (A),
but, it is almost same as soc_pcm_close().

	static int soc_pcm_open(xxx)
	{
		...
		if (ret &lt; 0)
			goto xxx_err;
		...
		return 0;

 ^	config_err:
 |		...
 |	rtd_startup_err:
(A)		...
 |	component_err:
 |		...
 v		return ret;
	}

The difference is
soc_pcm_close() is for all dai/component/substream,
rollback        is for succeeded part only.

This kind of duplicated code can be a hotbed of bugs,
thus, we want to share soc_pcm_close() and rollback.

Now, soc_pcm_open/close() are handling
	1) snd_soc_dai_startup/shutdown()
	2) snd_soc_link_startup/shutdown()
	3) snd_soc_component_module_get/put()
	4) snd_soc_component_open/close()
=&gt;	5) pm_runtime_put/get()

This patch is for 5) pm_runtime_put/get().

The idea of having bit-flag or counter is not enough for this purpose.
For example if one DAI is used for 2xPlaybacks for some reasons,
and if 1st Playback was succeeded but 2nd Playback was failed,
2nd Playback rollback doesn't need to call shutdown.
But it has succeeded bit-flag or counter via 1st Playback,
thus, 2nd Playback rollback will call unneeded shutdown.
And 1st Playback's necessary shutdown will not be called,
because bit-flag or counter was cleared by wrong 2nd Playback rollback.

To avoid such case, this patch marks substream pointer when get() was
succeeded. If rollback needed, it will check rollback flag and marked
substream pointer.

One note here is that it cares *current* get() only now.
but we might want to check *whole* marked substream in the future.
This patch is using macro named "push/pop", so that it can be easily
update.

soc_pcm_open() does rollback when failed (A),
but, it is almost same as soc_pcm_close().

	static int soc_pcm_open(xxx)
	{
		...
		if (ret &lt; 0)
			goto xxx_err;
		...
		return 0;

 ^	config_err:
 |		...
 |	rtd_startup_err:
(A)		...
 |	component_err:
 |		...
 v		return ret;
	}

The difference is
soc_pcm_close() is for all dai/component/substream,
rollback        is for succeeded part only.

This kind of duplicated code can be a hotbed of bugs,
thus, we want to share soc_pcm_close() and rollback.

Now, soc_pcm_open/close() are handling
=&gt;	1) snd_soc_dai_startup/shutdown()
	2) snd_soc_link_startup/shutdown()
	3) snd_soc_component_module_get/put()
	4) snd_soc_component_open/close()
	5) pm_runtime_put/get()

This patch is for 1) snd_soc_dai_startup/shutdown().

The idea of having bit-flag or counter is not enough for this purpose.
For example if one DAI is used for 2xPlaybacks for some reasons,
and if 1st Playback was succeeded but 2nd Playback was failed,
2nd Playback rollback doesn't need to call shutdown.
But it has succeeded bit-flag or counter via 1st Playback,
thus, 2nd Playback rollback will call unneeded shutdown.
And 1st Playback's necessary shutdown will not be called,
because bit-flag or counter was cleared by wrong 2nd Playback rollback.

To avoid such case, this patch marks substream pointer when startup() was
succeeded. If rollback needed, it will check rollback flag and marked
substream pointer.

One note here is that it cares *current* startup() only now.
but we might want to check *whole* marked substream in the future.
This patch is using macro named "push/pop", so that it can be easily
update.

<title>ASoC: Intel: add codec name prefix to ACPI machine description</title>

The current SOF machine driver adds a name prefix for each codec,
mainly to differentiate ALSA controls for left and right amplifiers.

This is a good idea, but the machine driver duplicates some of the
information that already exists in ACPI descriptors, so add those
prefixes there. Follow-up patches will make use of the information
encoded in these tables and remove duplication.

Use set_jack ops to set jack so machine drivers do not need to include
hdmi-codec.h explicitly.
