ACP hw block configuration differs across various distributions
and hence it's required to register different drivers module for
distributions. For now we support three ACP drivers:
* ACP without SOF use case
* ACP with SOF use case
* ACP with SOF use case for DMIC and non SOF for I2S endpoints
As all above driver registers with common PCI ID for ACP hw block
we need code to determine ACP configuration and auto select driver
module. This patch expose function that return configuration flag
based on dmi checks for a system. ACP driver module probe register
platform device based on such configuration flag to avoid conflict
with other ACP drivers probed for same PCI ID.

When we try to play and capture simultaneously we see that
interrupts are genrated but our handler is not being acknowledged,
After investigating further more in detail on this issue we found
that IRQ delivery via MSI from the ACP IP is unreliable and so sometimes
interrupt generated will not be acknowledged so MSI model shouldn't be used
and using legacy IRQs will resolve interrupt handling issue.
This patch replaces MSI interrupt handling with legacy IRQ model.
Issue can be reproduced easily by running below python script:
import subprocess
import time
import threading
def do2():
cmd = 'aplay -f dat -D hw:2,1 /dev/zero -d 1'
subprocess.call(cmd, stdin=subprocess.PIPE,
stderr=subprocess.PIPE, shell=True)
print('Play Done')
def run():
for i in range(1000):
do2()
def do(i):
cmd = 'arecord -f dat -D hw:2,2 /dev/null -d 1'
subprocess.call(cmd, stdout=subprocess.PIPE,
stderr=subprocess.PIPE, shell=True)
print(datetime.datetime.now(), i)
t = threading.Thread(target=run)
t.start()
for i in range(1000):
do(i)
t.join()
After applying this patch issue is resolved.

AMD Renoir driver tries to identify the presence of DMIC by evaluating
ACPI _WOV entry, and it returns -EINVAL when the ACPI call failed.
This ended up an error message like
snd_rn_pci_acp3x: probe of 0000:04:00.5 failed with error -22
although the system is correctly set up.
For avoiding such a superfluous error message, change the return value
to -ENODEV. Then the driver core just skips to the next one without
complaining.

The acp3x raven driver skips the probing when the given device isn't
connected with I2S. This skip behavior itself is fine, but the driver
also emits an error message "Invalid ACP audio mode" with KERN_ERR.
This isn't nice since it appears on the boot screen even if a boot
splash is running, although this itself is no real error.

Replacing string compare with "codec_dai->name" instead of comparing with
"codec_dai->component->name" in hw_params because,
Here the component name for codec RT1015 is "i2c-10EC5682:00"

Recently we found an issue about the suspend and resume. If dmic is
recording the sound, and we run suspend and resume, after the resume,
the dmic can't work well anymore. we need to close the app and reopen
the app, then the dmic could record the sound again.
For example, we run "arecord -D hw:CARD=acp,DEV=0 -f S32_LE -c 2
-r 48000 test.wav", then suspend and resume, after the system resume
back, we speak to the dmic. then stop the arecord, use aplay to play
the test.wav, we could hear the sound recorded after resume is weird,
it is not what we speak to the dmic.
I found two registers are set in the dai_hw_params(), if the two
registers are set during the resume, this issue could be fixed.
Move the code of the dai_hw_params() into the pdm_dai_trigger(), then
these two registers will be set during resume since pdm_dai_trigger()
will be called during resume. And delete the empty function
dai_hw_params().

Simultaneous capture on dmic and headset mic is having
issue with high hw_level being reported.
Issue Can be reproduced by:
arecord -D hw:2,0 -f dat -d 60 /tmp/test0 &
arecord -D hw:2,2 -f dat -d 60 /tmp/test1 &
cat /proc/asound/card2/pcm?c/sub0/status
Actual issue is :
When we open one capture stream on one instance lets say I2S_SP and then
once again if we open other capture on other instance lets say I2S_BT while
first capture is in progress and when we try to read the status of both
running instances by below command cat /proc/asound/card2/pcm?c/sub0/status
we observe that avail_max is being doubled on first opened
capture(I2S_SP in the example).
This is because our previous implementation was like when any instance is
opened it gets initialized in dma_open irrespective of on what instance it
called open.
For example:
First I2S_SP called opened it initializes both SP/BT capture streams
irrespective of on which instance the stream opened.next time I2S_BT
called opened and it initializes both SP/BT this corrupts the behaviour .
So with this patch the stream gets initialized only on specific instance
when ever it gets opened calls hw_params.
This rectifies the issue.

Some usages only call startup and shutdown without setting hw_params
(e.g. arecord --dump-hw-params). If we don't enable clk in startup, it
will cause ref count error because the clk will be disabled in shutdown.
For this reason, we should move enabling clk from hw_params to startup.
In addition, the hw_params is fixed in this driver(48000 rate, 2
channels, S16_LE format) so we don't need to change the clk rate after
the hw_params is set.

AMD platform device acp_audio_dma can only be created by parent PCI
device driver (drivers/gpu/drm/amd/amdgpu/amdgpu_acp.c). Pass struct
device of the parent to snd_pcm_lib_preallocate_pages() so
dma_alloc_coherent() can use correct dma_ops. Otherwise, it will
use default dma_ops which is nommu_dma_ops on x86_64 even when
IOMMU is enabled and set to non passthrough mode.
Though platform device inherits some dma related fields during its
creation in mfd_add_device(), we can't simply pass its struct device
to snd_pcm_lib_preallocate_pages() because dma_ops is not among the
inherited fields. Even it were, drivers/iommu/amd_iommu.c would
ignore it because get_device_id() doesn't handle platform device.
This change shouldn't give us any trouble even struct device of the
parent becomes null or represents some non PCI device in the future,
because get_dma_ops() correctly handles null struct device or uses
the default dma_ops if struct device doesn't have it set.

The pointer() callback gets its value by reading the I2S BYTE_COUNT
register. This is a 64-bit runnning transaction counter. If a
transaction was aborted in the middle of a sample buffer, the counter will
stop counting on a number divisible by the buffer size. Since we actually
use it as a pointer into an aligned buffer, however, we do want to ensure
that it always starts at a number divisible by the buffer size when
starting a transaction, hence we reset it whenever starting a transaction.
To accomplish this, it wasn't necessary to zero bytescount at the
termination of each transaction, so remove this unnecessary code.

On capture, audio data is first copied from I2S to ACP memory, and then
from ACP to SYSRAM. The I2S_TO_ACP_DMA interrupt fires on every sample
transferred from I2S to ACP memory. That is it fires ~48000 times per
second when capturing @ 48 kHz. Since we don't do anything on this
interrupt anyway, disable it to save quite a few unnecessary interrupts.
The real "work" (calling snd_pcm_period_elapsed()) is done when transfer
from ACP to SYSRAM is complete.

Commit 6b116dfb46 ("ASoC: AMD: make channel 1 dma as circular") made
both channels circular, so this comment and logic no longer applies. Always
stop ch2 (the channel closest to the output) before ch1. This ensures
that the downstream circular DMA channel does not continue to play/capture
repeated samples after the upstream circular DMA channel has already
stopped.
