The commit 2e6b836312a4 ("ASoC: intel: atom: Fix reference to PCM

substream->runtime->dma_addr as the buffer address may change
dynamically. However, I forgot that the dma_addr field is still not
set up for the CONTINUOUS buffer type (that this driver uses) yet in
5.14 and earlier kernels, and it resulted in garbage I/O. The problem
will be fixed in 5.15, but we need to address it quickly for now.
The fix is to deduce the address again from the DMA pointer with
virt_to_phys(), but from the right one, substream->runtime->dma_area.

ASoC: Fixes for v5.14
Quite a lot of fixes here, the biggest set being for the cs42l42 driver
which is reasonably old but has seen a sudden uptick in activity.
There's also some fixes for correctly referencing PCM buffer addresses
and the removal of some driver-local bodges that had been done for the
lack of prefix handling in DAPM which were broken by the core handling
that as expected.
I2S always has two LRCLK phases and both CH1 and CH2 of the RX
must be enabled (corresponding to the low and high phases of LRCLK.)
The selection of the valid data channels is done by setting the DAC
CHA_SEL and CHB_SEL. CHA_SEL is always the first (left) channel,
CHB_SEL depends on the number of active channels.
Previously for mono ASP CH2 was not enabled, the result was playing
mono data would not produce any audio output.
ASoC: cs42l42: Constrain sample rate to prevent illegal SCLK
The lowest valid SCLK corresponds to 44.1 kHz at 16-bit. Sample
rates less than this would produce SCLK below the minimum when using
a normal I2S frame. A constraint must be applied to prevent this.
The constraint is not applied if the machine driver sets SCLK, to
allow setups where the host generates additional bits per LRCLK
phase to increase the SCLK frequency. In these cases the machine
driver would always have to inform this driver of the actual SCLK,
and it must select a legal SCLK.
An I2S frame starts on the falling edge of LRCLK so ASP_STP must
be 0.
At the same time, move other format settings in the same register
from cs42l42_pll_config() to cs42l42_set_dai_fmt() where you'd
expect to find them, and merge into a single write.
ASoC: cs42l42: PLL must be running when changing MCLK_SRC_SEL
Both SCLK and PLL clocks must be running to drive the glitch-free mux
behind MCLK_SRC_SEL and complete the switchover.
This patch moves the writing of MCLK_SRC_SEL to when the PLL is started
and stopped, so that it only transitions while the PLL is running.
The unconditional write MCLK_SRC_SEL=0 in cs42l42_mute_stream() is safe
because if the PLL is not running MCLK_SRC_SEL is already 0.
ASoC: cs42l42: Remove duplicate control for WNF filter frequency
The driver was defining two ALSA controls that both change the same
register field for the wind noise filter corner frequency. The filter
response has two corners, at different frequencies, and the duplicate
controls most likely were an attempt to be able to set the value using
either of the frequencies.
However, having two controls changing the same field can be problematic
and it is unnecessary. Both frequencies are related to each other so
setting one implies exactly what the other would be.
Removing a control affects user-side code, but there is currently no
known use of the removed control so it would be best to remove it now
before it becomes a problem.

ALSA: seq: Fix racy deletion of subscriber
It turned out that the current implementation of the port subscription
is racy. The subscription contains two linked lists, and we have to
add to or delete from both lists. Since both connection and
disconnection procedures perform the same order for those two lists
(i.e. src list, then dest list), when a deletion happens during a
connection procedure, the src list may be deleted before the dest list
addition completes, and this may lead to a use-after-free or an Oops,
even though the access to both lists are protected via mutex.
The simple workaround for this race is to change the access order for
the disconnection, namely, dest list, then src list. This assures
that the connection has been established when disconnecting, and also
the concurrent deletion can be avoided.
The previous Kconfig cleanup added simplifications but also introduced
a new one by moving a boolean to a tristate. This leads to randconfig
problems.
This patch moves the select operations in the SOUNDWIRE_LINK_BASELINE
option. The INTEL_SOUNDWIRE config remains a tristate for backwards
compatibility with older configurations but is essentially an on/off
switch.

preallocation failed or a larger buffer is requested, and it's not

In clock find source function, we get value 0x2 for clock selector

Since clock source is valid so clock selector was not set again.
We pass through this function and start a playback stream(USB OUT transfer)
in 48Khz/32bit/2ch mode. This time we get value 0x1 for clock selector
and 0x1 for clock source. Finally clock id with this setting is 0x9.
Kernel-5.10 behavior
Clock selector was always set one more time even it is valid.
When we start a playback stream, we will get 0x2 for clock selector
and 0x1 for clock source. In this case clock id becomes 0xA.
This is an incorrect clock source setting and results in severe noises.
We see wrong data rate in USB IN transfer.

Merge series "arm64: tegra: Enable audio IOMMU support on Tegra194" from Thierry Reding <thierry.reding@gmail.com>
Thierry Reding <treding@nvidia.com>:
From: Thierry Reding <treding@nvidia.com>
This small series addresses a minor issue with how IOMMU support is
wired up on various Tegra generations. Currently the virtual "card"
device is used to allocate DMA memory for, but since that device does
not actually exist, the path to memory cannot be correctly described.
To address this, this series moves to using the ADMAIF as the DMA device
for audio. This is a real device that can have a proper DMA mask set and
with which a stream ID can be associated with in the SMMU. The memory
accesses technically originate from the ADMA controller (that the ADMAIF
uses), but DMA channel are dynamically allocated at runtime while DMA
memory is allocated at driver load time, drivers won't have access to
the ADMA device yet.
Further patches will be required to correct this issue on Tegra186 and
Tegra210, but I wanted to get feedback on this approach first.
Changes in v2:
- add backwards-compatibility fallback

ASoC: tegra: Use ADMAIF component for DMA allocations
DMA memory is currently allocated for the soundcard device, which is a
virtual device added for the sole purpose of "stitching" together the
audio device. It is not a real device and therefore doesn't have a DMA
mask or a description of the path to and from memory of accesses.
Memory accesses really originate from the ADMA controller that provides
the DMA channels used by the PCM component. However, since the DMA
memory is allocated up-front and the DMA channels aren't known at that
point, there is no way of knowing the DMA channel provider at allocation
time.
The next best physical device in the memory path is the ADMAIF. Use it
as the device to allocate DMA memory to. iommus and interconnects device
tree properties can thus be added to the ADMAIF device tree node to
describe the memory access path for audio.
I know nothing about zone_device pages and !device_private pages; but if
try_to_migrate_one() will do nothing for them, then it's better that
try_to_migrate() filter them first, than trawl through all their vmas.

mm/rmap: fix old bug: munlocking THP missed other mlocks
The kernel recovers in due course from missing Mlocked pages: but there
was no point in calling page_mlock() (formerly known as
try_to_munlock()) on a THP, because nothing got done even when it was
found to be mapped in another VM_LOCKED vma.
It's true that we need to be careful: Mlocked accounting of pte-mapped
THPs is too difficult (so consistently avoided); but Mlocked accounting
of only-pmd-mapped THPs is supposed to work, even when multiple mappings
are mlocked and munlocked or munmapped. Refine the tests.
There is already a VM_BUG_ON_PAGE(PageDoubleMap) in page_mlock(), so
page_mlock_one() does not even have to worry about that complication.
(I said the kernel recovers: but would page reclaim be likely to split
THP before rediscovering that it's VM_LOCKED? I've not followed that up)
