Some Ethernet PHYs (like marvell10g) will decide the host interface
mode by the media-side speed. So, the rswitch driver needs to
initialize one of the Ethernet SERDES (r8a779f0-eth-serdes) ports
after linked the Ethernet PHY up. The r8a779f0-eth-serdes driver has
.init() for initializing all ports and .power_on() for initializing
each port. So, add phy_power_{on,off} calling for it.

Intended to set phy_device->host_interfaces by phylink in the future.
But there is difficult to implement phylink properly, especially
supporting the in-band mode on this driver because extra initialization
is needed after linked the ethernet PHY up. So, convert to phy_device
from phylink.

After calling fwnode_phy_find_device(), the phy device refcount is
incremented. Then, when the phy device is attached to a netdev with
phy_attach_direct(), the refcount is also incremented but only
decremented in the caller if phy_attach_direct() fails. Move
phy_device_free() before the "if" to always release it correctly.
Indeed, either phy_attach_direct() failed and we don't want to keep a
reference to the phydev or it succeeded and a reference has been taken
internally.

Until now, the dell-wmi-ddv driver needs to be manually
patched and compiled to test compatibility with unknown
DDV WMI interface versions.
Add a module param to allow users to force loading even
when a unknown interface version was detected. Since this
might cause various unwanted side effects, the module param
is marked as unsafe.

While trying to solve a bugreport on bugzilla, i learned that
some devices (for example the Dell XPS 17 9710) provide a more
recent DDV WMI interface (version 3).
Since the new interface version just adds an additional method,
no code changes are necessary apart from whitelisting the version.

When calling debugfs_lookup() the result must have dput() called on it,
otherwise the memory will leak over time. To make things simpler, just
call debugfs_lookup_and_remove() instead which handles all of the logic

Conversion to gpiod API done in commit 468ba54bd616 ("fec: convert
to gpio descriptor") clashed with gpiolib applying the same quirk to the
reset GPIO polarity (introduced in commit b02c85c9458c). This results in
the reset line being left active/device being left in reset state when
reset line is "active low".
Remove handling of 'phy-reset-active-high' property from the driver and
rely on gpiolib to apply needed adjustments to avoid ending up with the
double inversion/flipped logic.

Conversion of the driver to gpiod API done in 468ba54bd616 ("fec:

resulted in aborting driver probe in cases where reset line was not

It turns out we can just modify the newer STM32 HASH driver

The Ux500 has a hash block which is an ancestor to the STM32
hash block. With some minor code path additions we can
support also this variant in the STM32 driver. Differences:
- Ux500 only supports SHA1 and SHA256 (+/- MAC) so we split
up the algorithm registration per-algorithm and register
each algorithm along with its MAC variant separately.
- Ux500 does not have an interrupt to indicate that hash
calculation is complete, so we add code paths to handle
polling for completion if the interrupt is missing in the
device tree.
- Ux500 is lacking the SR status register, to check if an
operating is complete, we need to poll the HASH_STR_DCAL
bit in the HASH_STR register instead.
- Ux500 had the resulting hash at address offset 0x0c and
8 32bit registers ahead. We account for this with a special
code path when reading out the hash digest.
- Ux500 need a special bit set in the control register before
performing the final hash calculation on an empty message.
- Ux500 hashes on empty messages will be performed if the
above bit is set, but are incorrect. For this reason we
just make an inline synchronous hash using a fallback
hash.
Tested on the Ux500 Golden device with the extended tests.

When calculating the hash using the CPU, right before the final
hash calculation, heavy testing on Ux500 reveals that it is wise
to wait for the hardware to go idle before calculating the
final hash.
The default test vectors mostly worked fine, but when I used the
extensive tests and stress the hardware I ran into this problem.

The ZLIB format (RFC 1950) is made of deflate compressed data surrounded
by a header and a footer. The QAT accelerators support only the deflate
algorithm, therefore the header and the footer need to be inserted in
software.
This adds logic in the QAT driver to support the ZLIB format. In
particular:
* Generalize the function qat_comp_alg_compress_decompress() to allow
skipping an initial region (header) of the source and/or destination
scatter lists.
* Add logic to register the qat_zlib_deflate algorithm into the acomp
framework.
* For ZLIB compression, skip the initial portion of the destination
buffer before sending the job to the QAT accelerator and insert the
ZLIB header and footer in the callback, after the QAT request has
been processed.
* For ZLIB decompression, parse the header in the input buffer
provided by the user and verify its validity before attempting the
decompression of the buffer with QAT. Then submit the buffer to QAT
for decompression. In the callback verify the correctness of the
footer by comparing the value of the ADLER produced by QAT with the
one in the destination buffer.

A summary of the flags being set for various drivers is given below.
Note that XDP_F_REDIRECT_TARGET and XDP_F_FRAG_TARGET are features
that can be turned off and on at runtime. This means that these flags
may be set and unset under RTNL lock protection by the driver. Hence,
READ_ONCE must be used by code loading the flag value.
Also, these flags are not used for synchronization against the availability
of XDP resources on a device. It is merely a hint, and hence the read
may race with the actual teardown of XDP resources on the device. This
may change in the future, e.g. operations taking a reference on the XDP
resources of the driver, and in turn inhibiting turning off this flag.
However, for now, it can only be used as a hint to check whether device
supports becoming a redirection target.

- netronome (nfp)

Commit 7a8b64d17e35 ("of/address: use range parser for of_dma_get_range")
converted the parsing of dma-range properties to use code shared with the
PCI range parser. The intent was to introduce no functional changes however
in the case where we fail to translate the first resource instead of
returning -EINVAL the new code we return 0. Restore the previous behaviour
by returning an error if we find no valid ranges, the original code only
handled the first range but subsequently support for parsing all supplied
ranges was added.
This avoids confusing code using the parsed ranges which doesn't expect to
successfully parse ranges but have only a list terminator returned, this
fixes breakage with so far as I can tell all DMA for on SoC devices on the
Socionext Synquacer platform which has a firmware supplied DT. A bisect
identified the original conversion as triggering the issues there.

On systems with two or fewer sockets, when the boot CPU has CONSTANT_TSC,
NONSTOP_TSC, and TSC_ADJUST, clocksource watchdog verification of the
TSC is disabled. This works well much of the time, but there is the
occasional production-level system that meets all of these criteria, but
which still has a TSC that skews significantly from atomic-clock time.
This is usually attributed to a firmware or hardware fault. Yes, the
various NTP daemons do express their opinions of userspace-to-atomic-clock
time skew, but they put them in various places, depending on the daemon
and distro in question. It would therefore be good for the kernel to
have some clue that there is a problem.
The old behavior of marking the TSC unstable is a non-starter because a
great many workloads simply cannot tolerate the overheads and latencies
of the various non-TSC clocksources. In addition, NTP-corrected systems
sometimes can tolerate significant kernel-space time skew as long as
the userspace time sources are within epsilon of atomic-clock time.
Therefore, when watchdog verification of TSC is disabled, enable it for
HPET and PMTMR (AKA ACPI PM timer). This provides the needed in-kernel
time-skew diagnostic without degrading the system's performance.

There is a "Win-Lock" key on HP Omen Laptops which supports
enabling and disabling the Windows key, which trigger commands 0x21a4
and 0x121a4 respectively. Currently the hp-wmi driver throws warnings
for this event. These can be ignored using KE_IGNORE as the
functionality is handled by the keyboard firmware itself.

ambiguities
We currently have a struct ssam_request_sync and a function
ssam_request_sync(). While this is valid C, there are some downsides to
it.
One of these is that current Sphinx versions (>= 3.0) cannot
disambiguate between the two (see disucssion and pull request linked
below). It instead emits a "WARNING: Duplicate C declaration" and links
for the struct and function in the resulting documentation link to the
same entry (i.e. both to either function or struct documentation)
instead of their respective own entries.
While we could just ignore that and wait for a fix, there's also a point
to be made that the current naming can be somewhat confusing when
searching (e.g. via grep) or trying to understand the levels of
abstraction at play:
We currently have struct ssam_request_sync and associated functions
ssam_request_sync_[alloc|free|init|wait|...]() operating on this struct.
However, function ssam_request_sync() is one abstraction level above
this. Similarly, ssam_request_sync_with_buffer() is not a function
operating on struct ssam_request_sync, but rather a sibling to
ssam_request_sync(), both using the struct under the hood.
Therefore, rename the top level request functions:
ssam_request_sync() -> ssam_request_do_sync()
ssam_request_sync_with_buffer() -> ssam_request_do_sync_with_buffer()
ssam_request_sync_onstack() -> ssam_request_do_sync_onstack()

The target ID of the base hub is currently set to KIP (keyboard/
peripherals). However, even though it manages such devices with the KIP
target ID, the base hub itself is actually accessed via the SAM target
ID. So set it accordingly.
Note that the target ID of the hub can be chosen arbitrarily and does
not directly correspond to any physical or virtual component of the EC.
This change is only a code improvement intended for consistency and
clarity, it does not fix an actual bug.
