commit feb00b736af64875560f371fe7f58b0b7f239046 upstream.
There is no reason to force readwrite access on TLV controls. It can be
either read, write or both. This is further evidenced in code where it
performs following checks:
if ((k->access & SNDRV_CTL_ELEM_ACCESS_TLV_READ) && !sbe->get)
return -EINVAL;
if ((k->access & SNDRV_CTL_ELEM_ACCESS_TLV_WRITE) && !sbe->put)
return -EINVAL;

[ Upstream commit f7d344a2bd5ec81fbd1ce76928fd059e57ec9bea ]
In the case like dmaengine which's not a dai but as a component, the
num_dai is zero, dmaengine component has the same component_of_node
as cpu dai, when cpu dai component is not ready, but dmaengine component
is ready, try to get cpu dai name, the snd_soc_get_dai_name() return
-EINVAL, not -EPROBE_DEFER, that cause below error:
asoc-simple-card <card name>: parse error -22
asoc-simple-card: probe of <card name> failed with error -22
The sound card failed to probe.
So this patch fixes the issue above by skipping the zero num_dai
component in searching dai name.

The Madera CODECs use regmap_irq functions but nothing ensures that
regmap_irq is built into the kernel. Add dependencies on the ASoC
symbols for the relevant MFD component. There is no point in building
the ASoC driver if the MFD doesn't support it and the MFD part contains
the necessary dependencies to ensure everything is built into the
kernel.

There is one call trace that snd_soc_register_card()
->snd_soc_bind_card()->soc_init_pcm_runtime()
->snd_soc_dai_compress_new()->snd_soc_new_compress().
In the trace the 'codec_dai' transfers from card->dai_link,
and we can see from the snd_soc_add_pcm_runtime() in
snd_soc_bind_card() that, if value of card->dai_link->num_codecs
is 0, then 'codec_dai' could be null pointer caused
by index out of bound in 'asoc_rtd_to_codec(rtd, 0)'.
And snd_soc_register_card() is called by various platforms.
Therefore, it is better to add the check in the case of misusing.
And because 'cpu_dai' has already checked in soc_init_pcm_runtime(),
there is no need to check again.
Adding the check as follow, then if 'codec_dai' is null,
snd_soc_new_compress() will not pass through the check
'if (playback + capture != 1)', avoiding the leftover use of
'codec_dai'.

snd_pcm_stop() calls with snd_pcm_stop_xrun().
The commit above introduced a deadlock as snd_pcm_stop_xrun() itself
takes the PCM stream lock while the caller already holds it. Since
the conversion was done only for consistency reason and the open-call
with snd_pcm_stop() to the XRUN state is a correct usage, let's revert
the commit back as the fix.

create an identically named control, it can never have loaded without

[ Upstream commit 4c33de0673ced9c7c37b3bbd9bfe0fda72340b2a ]
The current rt5682_jack_detect_handler() assumes the component
and card will always show up and implements an infinite usleep
loop waiting for them to show up.
This does not hold true if a codec interrupt (or other
event) occurs when the card is unbound. The codec driver's
remove or shutdown functions cannot cancel the workqueue due
to the wait loop. As a result, code can either end up blocking
the workqueue, or hit a kernel oops when the card is freed.
Fix the issue by rescheduling the jack detect handler in
case the card is not ready. In case card never shows up,
the shutdown/remove/suspend calls can now cancel the detect
task.

commit f7a6021aaf02088870559f82fc13c58cda7fea1a upstream.
If the device does not exist, of_get_child_by_name() will return NULL
pointer.
And devm_snd_soc_register_component() does not check it.
Also, I have noticed that cpcap_codec_driver has not been used yet.
Therefore, it should be better to check it in order to avoid the future
dereference of the NULL pointer.

commit e958b5884725dac86d36c1e7afe5a55f31feb0b2 upstream.
This patch is based on one in the Xilinx kernel tree, "ASoc: xlnx: Make
buffer bytes multiple of period bytes" by Devarsh Thakkar. The same
issue exists in the mainline version of the driver. The original
patch description is as follows:
"The Xilinx Audio Formatter IP has a constraint on period
bytes to be multiple of 64. This leads to driver changing
the period size to suitable frames such that period bytes
are multiple of 64.
Now since period bytes and period size are updated but not
the buffer bytes, this may make the buffer bytes unaligned
and not multiple of period bytes.
When this happens we hear popping noise as while DMA is being
done the buffer bytes are not enough to complete DMA access
for last period of frame within the application buffer boundary.
To avoid this, align buffer bytes too as multiple of 64, and
set another constraint to always enforce number of periods as
integer. Now since, there is already a rule in alsa core
to enforce Buffer size = Number of Periods * Period Size
this automatically aligns buffer bytes as multiple of period
bytes."

According to RM, the clock divider range is from 1 to 8, clock
prescaling ratio may be any power of 2 from 1 to 128.
So the supported divider is not all the value between
1 and 1024, just limited value in that range.
Create table for the supported divder and add function to
check the clock divider is available by comparing with
the table.
