Hi,

The IPC4 use of doorbell registers leaves some corner cases not well defined
and the 'correct sequences' are subjective in a sense.
The DSP doorbell registers are used as separate and independent channels and
the sequences for host -> DSP -> host (reply) can be racy.

For example:
The ACKing of a received message can happen before the firmware sends the reply
or it can as well happen after the reply has been sent and received by the host.
Both can be considered 'correct sequences' but they need different handling.

This series will allow the kernel to service any interpretation of the
sequencing on the firmware side.

Delete the doubled word "for" in comments.

All Intel drivers for cAVS platforms contain a sequence for S3 resume
which doesn't seem justified nor necessary. Forensic Git investigation
in internal repositories did not provide any rationale for the
implementation, and tests show no impact when those sequences are
removed.

This sequence was identified as problematic during a large HDaudio
cleanup where all programming sequences were revisited before
extensions are added.

Don't populate the read-only array ramp_base on the stack but
instead make it static const. Also makes the object code a

By acking a received message we tell the DSP that we have processed the
message (reply or notification) and we are open to receive a new one.

The original implementation did this in a common code after the received
message got handled as reply or notification.

With right timing this opens up a small window when we have processed the
reply and let the other thread proceed to send a new message to the DSP,
which is allowed as the DSP is free to receive message.
But when the message is received and processed by the DSP and it wants to
send a reply it will still see that the previous message has not been
acked, so it fails to send a reply. Later the first reply got acked by the
kernel, but it is too late and the in-flight message got a timeout due to
firmware not responding (which it tried, but could not).

Before attempting to send a message to the DSP we need to check if the
downstream BUSY flag has been cleared by the firmware to avoid lost IPC
messages by the firmware.

This is required by a firmware which only acks the received message after
it has sent a reply to the host.
With a bad luck, the host would send a message before the firmware gets to
the clearing the flag and thus losing a message.

Current error handling on snd_soc_dapm_add_route() has some wastes.
It indicates *own* error message *only* for sink or source,
and return error directly at (A). OTOH, it has similar error message at
(B) which indicates *both* sink/source.

And more, (A) is using dev_err(), (B) is using dev_warn().
(B) is caring prefix, but (A) is not.

(X)	int snd_soc_dapm_add_route(...)
	{
		...
		if (wsource == NULL) {
(A)			dev_err(...);
			return -ENODEV;
		}
		if (wsink == NULL) {
(A)			dev_err(...);
			return -ENODEV;
		}

		...

		ret = snd_soc_dapm_add_path(...);
		if (ret)
(B)			goto err;

		return 0;
	err:
(B)		dev_warn(...);
		return ret;
	}

Above snd_soc_dapm_add_route() (= X) is called from
snd_soc_dapm_add_routes() (= Y).
(X) will indicate error message by itself, but (Y) will indicate
own error message at (C). (C) is duplicated.

(Y)	int snd_soc_dapm_add_routes(...)
	{
		...
		for (...) {
(X)			int r = snd_soc_dapm_add_route(...);
			if (r < 0) {
(C)				dev_err(...);
				ret = r;
			}
			...
		}
		...
	}

This patch (1) merges these error message (= A,B) into one,
(2) use dev_err(), (3) remove duplicate error message (= C) from
snd_soc_dapm_add_routes().

By this patch, it will indicate error message like this.

	- error message with prefix
	- not found widget will have "(*)" mark
	- it indicates [control] if exists.

ex)
[if no sink with control]

	ASoC: Failed to add route SOURCE -> [CTRL] -> SINK(*)

[if no source without control]

	ASoC: Failed to add route SOURCE(*) -> SINK

The flow contains surprising parts that seem to have been inspired by
the Skylake driver.

During a resume from S3, the state of the links prior to suspend
should not matter. One would have to assume that the links are powered
down anyways prior to suspend, and there is also no specific code that
turns links on unconditionally on resume.

Likewise, the snd_hdac_init_chip() routine will start the cmd_io
handling, and it's not clear why we should care about the state of the
DMA prior to suspend.

This patch removes these two sequences to simplify the flow.

Commit cce6c149 ("ASoC: Intel: Skylake: add link management")
added a perfectly logical/symmetrical link handling for
'suspend_active' aka S0ix

However that commit also added a less obvious part, where during S3
resume the code will "turn off the links which are off before suspend"
as well as stop the cmd_io which is not started.

This sequence looks completely unnecessary and possibly wrong, remove it.

Two fixes are leading the way - one addresses the incorrect DMA mask
assignment (typo) at driver probe. The other, fixes a potential buffer
overflow when copying data received from firmware to kernel buffer.
However unlikely, the fix should still be there.

Then a range of patches providing the support for:
- AML with rt286 (machine board)
- KBL-R for rt298 (codec)
- KBL-R with rt298 (machine board)
- APL/KBL with da7219 (machine board)
- Addition of all the missing SKL-based PCI ids to core.c

Of the remaining changes, only one stands out - special case is provided
for "unsupported" IPCs. The driver supports a range of platforms,
however, on some generations given IPC may not be supported. Such call
shall not be treated as "invalid" - those are two different scenarios.

Everything else in the patchset is mostly a readability improvement:
spelling fixes and log messages issues, code simplification.

At a previous time, we have successfully created a virtual sound card
based on rpmsg. The sound card works under this mechanism Cortex-A core
tells the Cortex-M core the format, rate, channel, .etc configuration
of the PCM parameters and Cortex-M controls real hardware devices such
as SAI and DMA. From the view of Linux side, the sound card is bound to
a rpmsg channel through which it can access SAI.

Here these patches are introduced to create a new virtual sound card to
access MICFIL based on a new created rpmsg channel. It's easy to create
a new rpmsg channel for MICFIL through rpmsg name service announcment.
Also the other ASoC components bound to this rpmsg MICFIL sound card
will be registered with these patches.

If other sound cards using different hardware devices needs to be
created over rpmsg in the future, these patches can be referred.

The patchset fixes:
 - Line In path stays powered off during capturing or
   bypass to mixer.
 - incorrectly represented dB values in alsamixer, et al.
 - incorrect represented Capture input selector in alsamixer
   in Playback tab.
 - wrong control selected as Capture Master

The patchset improves:
 - Exposes output stage (post mixer) gain control and makes it new
   Master playback gain, DAC gain was the previous master.
   However, no Master mute now.
 - Exposes all mixer inputs (both Mics, LineIn and DAC) with their
   gain controls.
 - Exposes microphones widgets: single/differential input, boost.

Known issues:
 - Bypass path enablement isn't applied immediately, for make
   things going bit clock needs to be triggered for a bit,
   e.g. by aplay dummy.wav
   It might be a hardware bug, since the bit clock isn't
   declared as required for codec operation.

 - Ritmix RZX-50 (jz4755).
