ASoC: cs42l43: Sync the hp ilimit works when removing the component
Synchronise the headphone ilimit work functions when removing the
component. These can only trigger whilst the headphone is enabled which
shouldn't be possible once the component is removed but the works rely
on the stashed component pointer so they should be shut down before the
code moves on from component remove.

spi: imx: fix the burst length at DMA mode and CPU mode
For DMA mode, the bus width of the DMA is equal to the size of data
word, so burst length should be configured as bits per word.

For CPU mode, because of the spi transfer len is in byte, so calculate
the total number of words according to spi transfer len and bits per
word, burst length should be configured as total data bits.

ASoC: tas2781: add module parameter to tascodec_init()
The tascodec_init() of the snd-soc-tas2781-comlib module is called from
snd-soc-tas2781-i2c and snd-hda-scodec-tas2781-i2c modules. It calls
request_firmware_nowait() with parameter THIS_MODULE and a cont/callback
from the latter modules.

The latter modules can be removed while their callbacks are running,
resulting in a general protection failure.

Add module parameter to tascodec_init() so request_firmware_nowait() can
be called with the module of the callback.

3c3f2d13d3 arm64: dts: ti: k3-am625-beagleplay: Use the builtin mdio bus
The beagleplay dts was using a bit-bang gpio mdio bus as a work-around
for errata i2329. However since commit d04807b806 ("net: ethernet: ti:
davinci_mdio: Add workaround for errata i2329") the mdio driver itself
already takes care of this errata for effected silicon, which landed
well before the beagleplay dts. So i suspect the reason for the
workaround in upstream was simply due to copying the vendor dts.

Switch the dts to the ti,cpsw-mdio instead so it described the actual
hardware and is consistent with other AM625 based boards

8bc2973635 PM: hibernate: Add support for LZ4 compression for hibernation
Extend the support for LZ4 compression to be used with hibernation.
The main idea is that different compression algorithms
have different characteristics and hibernation may benefit when it uses
any of these algorithms: a default algorithm, having higher
compression rate but is slower(compression/decompression) and a
secondary algorithm, that is faster(compression/decompression) but has
lower compression rate.

LZ4 algorithm has better decompression speeds over LZO. This reduces
the hibernation image restore time.
As per test results:
                                    LZO             LZ4
Size before Compression(bytes)   682696704       682393600
Size after Compression(bytes)    146502402       155993547
Decompression Rate               335.02 MB/s     501.05 MB/s
Restore time                       4.4s             3.8s

LZO is the default compression algorithm used for hibernation. Enable
CONFIG_HIBERNATION_COMP_LZ4 to set the default compressor as LZ4.

b3decc5ce7 media: mc: Expand MUST_CONNECT flag to always require an enabled link
The MEDIA_PAD_FL_MUST_CONNECT flag indicates that the pad requires an
enabled link to stream, but only if it has any link at all. This makes
little sense, as if a pad is part of a pipeline, there are very few use
cases for an active link to be mandatory only if links exist at all. A
review of in-tree drivers confirms they all need an enabled link for
pads marked with the MEDIA_PAD_FL_MUST_CONNECT flag.

Expand the scope of the flag by rejecting pads that have no links at
all. This requires modifying the pipeline build code to add those pads
to the pipeline.

eb2f932100 media: nxp: imx8-isi: Check whether crossbar pad is non-NULL before access
When translating source to sink streams in the crossbar subdev, the
driver tries to locate the remote subdev connected to the sink pad. The
remote pad may be NULL, if userspace tries to enable a stream that ends
at an unconnected crossbar sink. When that occurs, the driver
dereferences the NULL pad, leading to a crash.

Prevent the crash by checking if the pad is NULL before using it, and
return an error if it is.

422f7af75d media: mc: Fix flags handling when creating pad links
The media_create_pad_link() function doesn't correctly clear reject link
type flags, nor does it set the DATA_LINK flag. It only works because
the MEDIA_LNK_FL_DATA_LINK flag's value is 0.

Fix it by returning an error if any link type flag is set. This doesn't
introduce any regression, as nobody calls the media_create_pad_link()
function with link type flags (easily checked by grepping for the flag
in the source code, there are very few hits).

Set the MEDIA_LNK_FL_DATA_LINK explicitly, which is a no-op that the
compiler will optimize out, but is still useful to make the code more
explicit and easier to understand.

78f0daa026 media: mc: Add local pad to pipeline regardless of the link state
When building pipelines by following links, the
media_pipeline_explore_next_link() function only traverses enabled
links. The remote pad of a disabled link is not added to the pipeline,
and neither is the local pad. While the former is correct as disabled
links should not be followed, not adding the local pad breaks processing
of the MEDIA_PAD_FL_MUST_CONNECT flag.

The MEDIA_PAD_FL_MUST_CONNECT flag is checked in the
__media_pipeline_start() function that iterates over all pads after
populating the pipeline. If the pad is not present, the check gets
skipped, rendering it useless.

Fix this by adding the local pad of all links regardless of their state,
only skipping the remote pad for disabled links.

a06c6f5d3c PM: hibernate: Move to crypto APIs for LZO compression
Currently for hibernation, LZO is the only compression algorithm
available and uses the existing LZO library calls. However, there
is no flexibility to switch to other algorithms which provides better
results. The main idea is that different compression algorithms have
different characteristics and hibernation may benefit when it uses
alternate algorithms.

By moving to crypto based APIs, it lays a foundation to use other
compression algorithms for hibernation. There are no functional changes
introduced by this approach.

96db0f947a PM: sleep: Move devices to new lists earlier in each suspend phase
During a system-wide suspend of devices, dpm_noirq_suspend_devices(),
dpm_suspend_late() and dpm_suspend() move devices from one list to
another.  They do it with each device after its PM callback in the
given suspend phase has run or has been scheduled for asynchronous
execution, in case it is deleted from the current list in the
meantime.

However, devices can be moved to a new list before invoking their PM
callbacks (which usually is the case for the devices whose callbacks
are executed asynchronously anyway), because doing so does not affect
the ordering of that list.  In either case, each device is moved to
the new list after the previous device has been moved to it or gone
away, and if a device is removed, it does not matter which list it is
in at that point, because deleting an entry from a list does not change
the ordering of the other entries in it.

Accordingly, modify the functions mentioned above to move devices to
new lists without waiting for their PM callbacks to run regardless of
whether or not they run asynchronously.

No intentional functional impact.

If the handling of two or more devices fails in one suspend-resume
phase, it should be counted once in the statistics which is not
guaranteed to happen during system-wide resume of devices due to
the possible asynchronous execution of device callbacks.

Address this by using the async_error static variable during system-wide
device resume to indicate that there has been a device resume error and
the given suspend-resume phase should be counted as failing.

9ff544fa5f PM: sleep: stats: Define suspend_stats next to the code using it
It is not necessary to define struct suspend_stats in a header file and the
suspend_stats variable in the core device system-wide PM code.  They both
can be defined in kernel/power/main.c, next to the sysfs and debugfs code
accessing suspend_stats, which can be static.

Modify the code in question in accordance with the above observation and
replace the static inline functions manipulating suspend_stats with
regular ones defined in kernel/power/main.c.

While at it, move the enum suspend_stat_step to the end of suspend.h which
is a more suitable place for it.

It is good practice to directly include all headers used, it avoids
