ASoC: amd: Downgrade print level for invalid ACP mode
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.

Downgrade the print level to KERN_INFO so that this message won't
appear on the console unnecessarily.

ASoC: AMD: Restore PME_EN state at Power On
PME_EN state needs to restored to the value set by fmw.
For the devices which are not using I2S wake event which gets
enabled by PME_EN bit, keeping PME_EN enabled burns considerable amount
of power as it blocks low power state.
For the devices using I2S wake event, PME_EN gets enabled in fmw and the
state should be maintained after ACP Power On.

Merge series "ASoC: topology: fix error handling flow" from Pierre-Louis Bossart <pierre-louis.bossart@linux.intel.com>:
While experimenting and introducing errors in Baytrail topology files
until I got them right, I encountered multiple kernel oopses and
memory leaks. This is a first batch to harden the code, but we should
probably think of a tool to fuzz the topology...

Pierre-Louis Bossart (5):
  ASoC: topology: fix kernel oops on route addition error
  ASoC: topology: fix tlvs in error handling for widget_dmixer
  ASoC: topology: use break on errors, not continue
  ASoC: topology: factor kfree(se) in error handling
  ASoC: topology: add more logs when topology load fails.

ASoC: amd :High hw_level while simultaneous capture
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.

ASoC: amd: acp3x: use dma address for acp3x dma driver
We shouldn't assume CPU physical address we get from page_to_phys()
is same as DMA address we get from dma_alloc_coherent(). On x86_64,
we won't run into any problem with the assumption when dma_ops is
nommu_dma_ops. However, DMA address is IOVA when IOMMU is enabled.
And it's most likely different from CPU physical address when AMD
IOMMU is not in passthrough mode.

This patch fixes page faults when IOMMU is enabled.

ASoC: amd: acp3x: use dma_ops of parent device for acp3x dma driver
AMD platform device acp3x_rv_i2s created by parent PCI device
driver. 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.

We should pass a proper non-NULL device object to memory allocators
although it was accepted in the past.  The card->dev points to the
most appropriate device object in such a case, so let's put it.

ASoC: amd: Fix potential NULL pointer dereference
Check return value from call to devm_kzalloc() in order to prevent a
potential NULL pointer dereference.

Also, notice that it makes no sense to allocate any resources if
res = platform_get_resource(pdev, IORESOURCE_MEM, 0); fails,
so move the call to devm_kzalloc() below the mentioned code.

Lastly, improve the use of sizeof in the call to devm_kzalloc() by
changing it from sizeof(struct i2s_dev_data) to sizeof(*adata)

This issue was detected with the help of Coccinelle.
