"In this cycle, tail-packing data inline for compressed files is now
supported so that tail pcluster can be stored and read together with
inode metadata in order to save data I/O and storage space.
In addition to that, to prepare for the upcoming subpage, folio and
fscache features, we also introduce meta buffers to get rid of
erofs_get_meta_page() since it was too close to the page itself.
In addition, in order to show supported kernel features and control
sync decompression strategy, new sysfs nodes are introduced in this
cycle as well.

Merge tag 'fs.idmapped.v5.17' of git://git.kernel.org/pub/scm/linux/kernel/git/brauner/linux
Pull fs idmapping updates from Christian Brauner:
"This contains the work to enable the idmapping infrastructure to
support idmapped mounts of filesystems mounted with an idmapping.
In addition this contains various cleanups that avoid repeated
open-coding of the same functionality and simplify the code in quite a
few places.
We also finish the renaming of the mapping helpers we started a few
kernel releases back and move them to a dedicated header to not
continue polluting the fs header needlessly with low-level idmapping
helpers. With this series the fs header only contains idmapping
helpers that interact with fs objects.
Currently we only support idmapped mounts for filesystems mounted
without an idmapping themselves. This was a conscious decision
mentioned in multiple places (cf. [1]).
As explained at length in [3] it is perfectly fine to extend support
for idmapped mounts to filesystem's mounted with an idmapping should
the need arise. The need has been there for some time now (cf. [2]).
Before we can port any filesystem that is mountable with an idmapping
to support idmapped mounts in the coming cycles, we need to first
extend the mapping helpers to account for the filesystem's idmapping.
This again, is explained at length in our documentation at [3] and
also in the individual commit messages so here's an overview.
Currently, the low-level mapping helpers implement the remapping
algorithms described in [3] in a simplified manner as we could rely on
the fact that all filesystems supporting idmapped mounts are mounted
without an idmapping.
In contrast, filesystems mounted with an idmapping are very likely to
not use an identity mapping and will instead use a non-identity
mapping. So the translation step from or into the filesystem's
idmapping in the remapping algorithm cannot be skipped for such
filesystems.
Non-idmapped filesystems and filesystems not supporting idmapped
mounts are unaffected by this change as the remapping algorithms can
take the same shortcut as before. If the low-level helpers detect that
they are dealing with an idmapped mount but the underlying filesystem
is mounted without an idmapping we can rely on the previous shortcut
and can continue to skip the translation step from or into the
filesystem's idmapping. And of course, if the low-level helpers detect
that they are not dealing with an idmapped mount they can simply
return the relevant id unchanged; no remapping needs to be performed
at all.
These checks guarantee that only the minimal amount of work is
performed. As before, if idmapped mounts aren't used the low-level
helpers are idempotent and no work is performed at all"

"The gpio-sim module is back, this time without any changes to
configfs. This results in a less elegant user-space interface but I
never got any follow-up on the committable items and didn't want to
delay this module for several more months.
Other than that we have support for several new models and some
support going away. We started working on converting GPIO drivers to
using fwnode exclusively in order to limit references to OF symbols to
gpiolib-of.c exclusively. We also have regular tweaks and improvements
all over the place.

- Removal of support for Netlogic devices from the XLP driver, the
platform had previously been removed by MIPS so the support couldn't
be used.

Pull spi updates from Mark Brown:
"This has mostly been a quiet release for the SPI subsystem, almost all
cleanups and fixes to existing drivers.
A couple of changes that stand out:
- Cleanups and support for version specific features in the
DesignWare controller.
- Removal of support for Netlogic devices from the XLP driver, the
platform had previously been removed by MIPS so the support
couldn't be used.
- Conversion of several DT bindings to YAML format"

This has been a fairly quiet release for the regulator API, the main
thing has been the addition of helpers for interrupt handling from Matti
Vaittinen. We do also have support for quite a few new devices and
included in here is a platform/x86 patch series for Intel INT3472 ACPI
devices which this is a dependency for the TPS68470 driver.
- Helpers for trivial interrupt notifications, making it easier for
drivers to handle error interrupts.
- Support for Dialog DA914x, Maxim MAX2008x, Qualcomm PM8826, PMG1100,
and PM8450 and TI TPS68470

The UFS for Exynos7 SoC clock controller requires additional input
clocks for the FSYS1 clock controller. Update the bindings to reflect
this, at least in theory. In practice, these input clocks are ignored,
so it is rather adjusting of bindings to existing DTS, without affecting
any real users. I understand that is not how it should be done,
though...

The '/bits/ 64' notation applies the next <> list of values. Another <> list
is encoded as 32-bits by default. IOW, each <> list needs to be preceeded

While the dts format allows this, as a rule we don't mix sizes for DT

The schemas for MDIO bus nodes range from missing to duplicating
everything in mdio.yaml. The MDIO bus node schemas only need to
reference mdio.yaml, define any binding specific properties, and define
'unevaluatedProperties: false'. This ensures that MDIO nodes only
contain defined properties. With this, any duplicated properties can
be removed.

Merge tag 'rcu.2022.01.09a' of git://git.kernel.org/pub/scm/linux/kernel/git/paulmck/linux-rcu
Pull RCU updates from Paul McKenney:
- Documentation updates, perhaps most notably Neil Brown's writeup of
the reference-counting analogy to RCU.
- Expedited grace-period cleanups.
- Remove CONFIG_RCU_FAST_NO_HZ due to lack of valid users. I have asked
around, posted a blog entry, and sent this series to LKML without
result.
- Miscellaneous fixes.
- RCU callback offloading updates, perhaps most notably Frederic
Weisbecker's updates allowing CPUs booted in the de-offloaded state
to be offloaded at runtime.
- nolibc fixes from Willy Tarreau and Anmar Faizi, but also including
Mark Brown's addition of gettid().
- RCU Tasks Trace fixes, including changes that increase the
scalability of call_rcu_tasks_trace() for the BPF folks (Martin Lau
and KP Singh).
- Various fixes including those from Wander Lairson Costa and Li
Zhijian.
- Fixes plus addition of tests for the increased call_rcu_tasks_trace()
scalability.

Core
----
- Defer freeing TCP skbs to the BH handler, whenever possible,
or at least perform the freeing outside of the socket lock section
to decrease cross-CPU allocator work and improve latency.
- Add netdevice refcount tracking to locate sources of netdevice
and net namespace refcount leaks.
- Make Tx watchdog less intrusive - avoid pausing Tx and restarting
all queues from a single CPU removing latency spikes.
- Various small optimizations throughout the stack from Eric Dumazet.
- Make netdev->dev_addr[] constant, force modifications to go via
appropriate helpers to allow us to keep addresses in ordered data
structures.
- Replace unix_table_lock with per-hash locks, improving performance
of bind() calls.
- Extend skb drop tracepoint with a drop reason.
- Allow SO_MARK and SO_PRIORITY setsockopt under CAP_NET_RAW.
BPF
---
- New helpers:
- bpf_find_vma(), find and inspect VMAs for profiling use cases
- bpf_loop(), runtime-bounded loop helper trading some execution
time for much faster (if at all converging) verification
- bpf_strncmp(), improve performance, avoid compiler flakiness
- bpf_get_func_arg(), bpf_get_func_ret(), bpf_get_func_arg_cnt()
for tracing programs, all inlined by the verifier
- Support BPF relocations (CO-RE) in the kernel loader.
- Further the support for BTF_TYPE_TAG annotations.
- Allow access to local storage in sleepable helpers.
- Convert verifier argument types to a composable form with different
attributes which can be shared across types (ro, maybe-null).
- Prepare libbpf for upcoming v1.0 release by cleaning up APIs,
creating new, extensible ones where missing and deprecating those
to be removed.

Merge tag '5.17-net-next' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next
Pull networking updates from Jakub Kicinski:
"Core
----
- Defer freeing TCP skbs to the BH handler, whenever possible, or at
least perform the freeing outside of the socket lock section to
decrease cross-CPU allocator work and improve latency.
- Add netdevice refcount tracking to locate sources of netdevice and
net namespace refcount leaks.
- Make Tx watchdog less intrusive - avoid pausing Tx and restarting
all queues from a single CPU removing latency spikes.
- Various small optimizations throughout the stack from Eric Dumazet.
- Make netdev->dev_addr[] constant, force modifications to go via
appropriate helpers to allow us to keep addresses in ordered data
structures.
- Replace unix_table_lock with per-hash locks, improving performance
of bind() calls.
- Extend skb drop tracepoint with a drop reason.
- Allow SO_MARK and SO_PRIORITY setsockopt under CAP_NET_RAW.
BPF
---
- New helpers:
- bpf_find_vma(), find and inspect VMAs for profiling use cases
- bpf_loop(), runtime-bounded loop helper trading some execution
time for much faster (if at all converging) verification
- bpf_strncmp(), improve performance, avoid compiler flakiness
- bpf_get_func_arg(), bpf_get_func_ret(), bpf_get_func_arg_cnt()
for tracing programs, all inlined by the verifier
- Support BPF relocations (CO-RE) in the kernel loader.
- Further the support for BTF_TYPE_TAG annotations.
- Allow access to local storage in sleepable helpers.
- Convert verifier argument types to a composable form with different
attributes which can be shared across types (ro, maybe-null).
- Prepare libbpf for upcoming v1.0 release by cleaning up APIs,
creating new, extensible ones where missing and deprecating those
to be removed.
Protocols
---------
- WiFi (mac80211/cfg80211):
- notify user space about long "come back in N" AP responses,
allow it to react to such temporary rejections
- allow non-standard VHT MCS 10/11 rates
- use coarse time in airtime fairness code to save CPU cycles
- Bluetooth:
- rework of HCI command execution serialization to use a common
queue and work struct, and improve handling errors reported in
the middle of a batch of commands
- rework HCI event handling to use skb_pull_data, avoiding packet
parsing pitfalls
- support AOSP Bluetooth Quality Report
- SMC:
- support net namespaces, following the RDMA model
- improve connection establishment latency by pre-clearing buffers
- introduce TCP ULP for automatic redirection to SMC
- Multi-Path TCP:
- support ioctls: SIOCINQ, OUTQ, and OUTQNSD
- support socket options: IP_TOS, IP_FREEBIND, IP_TRANSPARENT,
IPV6_FREEBIND, and IPV6_TRANSPARENT, TCP_CORK and TCP_NODELAY
- support cmsgs: TCP_INQ
- improvements in the data scheduler (assigning data to subflows)
- support fastclose option (quick shutdown of the full MPTCP
connection, similar to TCP RST in regular TCP)
- MCTP (Management Component Transport) over serial, as defined by
DMTF spec DSP0253 - "MCTP Serial Transport Binding".
Driver API
----------
- Support timestamping on bond interfaces in active/passive mode.
- Introduce generic phylink link mode validation for drivers which
don't have any quirks and where MAC capability bits fully express
what's supported. Allow PCS layer to participate in the validation.
Convert a number of drivers.
- Add support to set/get size of buffers on the Rx rings and size of
the tx copybreak buffer via ethtool.
- Support offloading TC actions as first-class citizens rather than
only as attributes of filters, improve sharing and device resource
utilization.
- WiFi (mac80211/cfg80211):
- support forwarding offload (ndo_fill_forward_path)
- support for background radar detection hardware
- SA Query Procedures offload on the AP side
New hardware / drivers

I've taken this through the SoC tree in the anticipation of adding a
few other Arm based SoCs as well, but those did not pass the review in
time, so it's only this one"

As usual, this is the bulk of the updates for the SoC tree, adding
more devices to existing files, addressing issues from ever improving
automated checking, and fixing minor issues.
The most interesting bits as usual are the new platforms.
All the newly supported SoCs belong into existing families
this time:
- Qualcomm gets support for two newly announced platforms, both
of which can now work in production environments: the SDX65
5G modem that can run a minimal Linux on its Cortex-A7 core,
and the Snapdragon 8 Gen 1, their latest high-end phone SoC.
- Renesas adds support for R-Car S4-8, the most recent automotive
Server/Communication SoC.
- TI adds support for J721s2, a new automotive SoC in the K3
family.
- Mediatek MT7986a/b is a SoC used in Wifi routers, the latest
generation following their popular MT76xx series. Only basic
support is added for now.
- NXP i.MX8 ULP8 is a new low-power variant of the widespread
i.MX8 series.
- TI SPEAr320s is a minor variant of the old SPEAr320 SoC that
we have supported for a long time.
New boards with the existing SoCs include
- Aspeed AST2500/AST2600 BMCs in TYAN, Facebook and Yadro servers
- AT91/SAMA5 based evaluation board
- NXP gains twenty new development and industrial boards for their
i.MX and Layerscape SoCs
- Intel IXP4xx now supports the final two machines in device tree
that were previously only supported in old style board files.
- Mediatek MT6589 is used in the Fairphone FP1 phone from 2013,
while MT8183 is used in the Acer Chromebook 314.
- Qualcomm gains support for the reference machines using the two
new SoCs, plus a number of Chromebook variants and phones based
on the Snapdragon 7c, 845 and 888 SoCs, including various
Sony Xperia devices and the Microsoft Surface Duo 2.
- ST STM32 now supports the Engicam i.Core STM32MP1 carrier board.
- Tegra now boots various older Android devices based on 32-bit
chips out of the box, including a number of ASUS Transformer
tablets.
There is also a new Jetson AGX Orin developer kit.
- Apple support adds the missing device trees for all the remaining
M1 Macbook and iMac variants, though not yet the M1 Pro/Max
versions.
- Allwinner now supports another version of the Tanix TX6 set-top
box based on the H6 SoC.
- Broadcom gains support for the Netgear RAXE500 Wireless router
based on BCM4908.

Pull clocksource watchdog updates from Paul McKenney:
- Avoid accidental unstable marking of clocksources by rejecting
clocksource measurements where the source of the skew is the delay
reading reference clocksource itself. This change avoids many of the
current false positives caused by epic cache-thrashing workloads.
- Reduce the default clocksource_watchdog() retries to 2, thus offsetting
the increased overhead due to #1 above rereading the reference
clocksource.

As has been discussed some time ago on ksumitt-discuss@ mailinglist,
the need for trivial tree diminished over time as all the tooling and
processess became much more mature and it's quite natural these days
for trivial patches to flow through subsystem trees anyway, so the
spin-off of a trivial tree doesn't make sense any more, and is not worth
the merge conflicts it might sometimes create.
So remove any mentions of it from kernel documentation for good.

sysfs documentation is supposed to go in Documentation/ABI/.
However, /sys/block/<disk>/queue/* are documented in
Documentation/block/queue-sysfs.rst, and sometimes redundantly in
Documentation/ABI/stable/sysfs-block too.
Let's consolidate this documentation into Documentation/ABI/.
Therefore, copy the relevant docs from queue-sysfs.rst into sysfs-block.
This primarily means adding the 25 missing files that were documented in
queue-sysfs.rst only, as well as mentioning the RO/RW status of files.
Documentation/ABI/ requires "Date" and "Contact" fields. For the Date
fields, I used the date of the commit which added support for each file.
For the "Contact" fields, I used linux-block.

Sort the documentation for the files alphabetically by file path so that
there is a logical order and it's clear where to add new files.
With two small exceptions, this patch doesn't change the documentation
itself and just reorders it:
- In /sys/block/<disk>/<part>/stat, I replaced <part> with <partition>
to be consistent with the other files.
- The description for /sys/block/<disk>/<part>/stat referred to another
file "above", which I reworded.

This appears to be an oversight, so fix it by allowing the properties

This converts the Zinitix BT4xx and BT5xx touchscreen bindings to YAML,
fix them up a bit and extends them.
We list all the existing BT4xx and BT5xx components with compatible
strings. These are all similar, use the same bindings and work in
similar ways.
We rename the supplies from the erroneous vdd/vddo to the actual supply
names vcca/vdd as specified on the actual component. It is long
established that supplies shall be named after the supply pin names of a
component. The confusion probably stems from that in a certain product
the rails to the component were named vdd/vddo. Drop some notes on how OS
implementations should avoid confusion by first looking for vddo, and if
that exists assume the legacy binding pair and otherwise use vcca/vdd.
Add reset-gpios as sometimes manufacturers pulls a GPIO line to the reset
line on the chip.
Add optional touchscreen-fuzz-x and touchscreen-fuzz-y properties.

A few more fixes have come in, nothing overly severe but would be good
to get in by final release:
- More specific compatible fields on the qspi controller for socfpga,
to enable quirks in the driver.
- A runtime PM fix for Renesas to fix mismatched reference counts on
errors.

Since commit d18b01789a ("docs: Add automatic cross-reference for
documentation pages"), references that were already explicitly defined
with "ref:" and referred to other pages with a path have been doubled.
This is reported as the following error by Firefox:
Start tag "a" seen but an element of the same type was already open.
End tag "a" violates nesting rules.
As well as the invalid HTML, this also obscures the URI fragment links
to subsections because the second link overrides the first. For example
on the page admin-guide/hw-vuln/mds.html the last link should be to the
"Default Mitigations" subsection using a # URI fragment:
admin-guide/hw-vuln/l1tf.html#default-mitigations
But it is obsured by a second link to the whole page:
admin-guide/hw-vuln/l1tf.html
The full HTML with the double <a> tags looks like this:
<a class="reference internal" href="l1tf.html#default-mitigations">
<span class="std std-ref">
<a class="reference internal" href="l1tf.html">
<span class="doc">L1TF - L1 Terminal Fault</span>
</a>
</span>
</a>
After this commit, there is only a single link:
<a class="reference internal" href="l1tf.html#default-mitigations">
<span class="std std-ref">Documentation/admin-guide/hw-vuln//l1tf.rst</span>
</a>
Now that the second link is removed, the browser correctly jumps to the
default-mitigations subsection when clicking the link.
The fix is to check that nodes in the document to be modified are not
already references. A reference is counted as any text that is a
descendant of a reference type node. Only plain text should be converted
to new references, otherwise the doubling occurs.
Testing
=======
* Test that the build stdout is the same (ignoring ordering), and that
no new warnings are printed.
* Diff all .html files and check that the only modifications occur
to the bad double links.
* The auto linking of bare references to pages without "ref:" is still
working.

This adds basic support for delivering 2 level event channels to a guest.
Initially, it only supports delivery via the IRQ routing table, triggered
by an eventfd. In order to do so, it has a kvm_xen_set_evtchn_fast()
function which will use the pre-mapped shared_info page if it already
exists and is still valid, while the slow path through the irqfd_inject
workqueue will remap the shared_info page if necessary.
It sets the bits in the shared_info page but not the vcpu_info; that is
deferred to __kvm_xen_has_interrupt() which raises the vector to the
appropriate vCPU.
Add a 'verbose' mode to xen_shinfo_test while adding test cases for this.

Use the newly reinstated gfn_to_pfn_cache to maintain a kernel mapping
of the Xen shared_info page so that it can be accessed in atomic context.
Note that we do not participate in dirty tracking for the shared info
page and we do not explicitly mark it dirty every single tim we deliver
an event channel interrupts. We wouldn't want to do that even if we *did*
have a valid vCPU context with which to do so.

2) Trivial fixes/updates/cleanup to mlx5e netdev driver
3) Fix htmldoc build warning
4) Spread mlx5 SFs (sub-functions) to all available CPU cores: Commits 1..5
Shay Drory Says:
================
Before this patchset, mlx5 subfunction shared the same IRQs (MSI-X) with
their peers subfunctions, causing them to use same CPU cores.
In large scale, this is very undesirable, SFs use small number of cpu
cores and all of them will be packed on the same CPU cores, not
utilizing all CPU cores in the system.
In this patchset we want to achieve two things.
a) Spread IRQs used by SFs to all cpu cores
b) Pack less SFs in the same IRQ, will result in multiple IRQs per core.
In this patchset, we spread SFs over all online cpus available to mlx5
irqs in Round-Robin manner. e.g.: Whenever a SF is created, pick the next
CPU core with least number of SF IRQs bound to it, SFs will share IRQs on
the same core until a certain limit, when such limit is reached, we
request a new IRQ and add it to that CPU core IRQ pool, when out of IRQs,
pick any IRQ with least number of SF users.
This enhancement is done in order to achieve a better distribution of
the SFs over all the available CPUs, which reduces application latency,
as shown bellow.

Xen on Arm has gained new support recently to calculate and report
extended regions (unused address space) safe to use for external
mappings. These regions are reported via "reg" property under
"hypervisor" node in the guest device-tree. As region 0 is reserved
for grant table space (always present), the indexes for extended
regions are 1...N.
No device-tree bindings update is needed (except clarifying the text)
as guest infers the presence of extended regions from the number
of regions in "reg" property.
While at it, remove the following sentence:
"This property is unnecessary when booting Dom0 using ACPI."
for "reg" and "interrupts" properties as the initialization is not
done via device-tree "hypervisor" node in that case anyway.

The config RANDOMIZE_SLAB does not exist, the authors probably intended to
refer to the config RANDOMIZE_BASE, which provides kernel address-space
randomization. They probably just confused SLAB with BASE (these two
four-letter words coincidentally share three common letters), as they also
point out the config SLAB_FREELIST_RANDOM as further randomization within
the same sentence.
Fix the reference of the config for kernel address-space randomization to
the config that provides that.

Most readers are probably going to figure out that the config is actually
all upper-case letters, as all Kconfig symbols are this way.
Properly capitalizing makes the script ./scripts/checkkconfigsymbols.py
happy, which otherwise would report this as a reference to a non-existing
Kconfig symbol.
So, use the right capitalization for the MAGIC_SYSRQ config in the kgdb

A small additional set of things that just missed the previous
pull request and have mostly been through plenty of review before the
holiday period began (or are trivial). I've not taken some other series
on the list to allow for more eyes after the holiday period.
New device support
* adi,admv1013
- New driver for this wideband microwave upconverter including dt-bindings
and some device specific ABI due to the need to describe phase calibrations
of a differential channel on both i and q phases. Previously we could
do differential or i/q but not both on the same channel. The driver
ABI uses a workaround for core support which will do until we know if
this is a common requirement for which a more generic solution is
needed.
MAINTAINERS:
* Add Haibo Chen as a maintainer for various NXP SoC ADCs.
Minor cleanup:
* sunrise_co2
- Make sure an uninitialized value isn't used to set *val in read_raw().
Not a real bug, but a compiler or reviewer can't tell that based
on what they can see locally.

Each cluster has its own dedicated watchdog timer. Those WDT instances
are controlled using different bits in PMU registers, new
"samsung,index" property is added to tell the driver which bits to use
for defined watchdog node.

Introduce the pfr_update driver which can be used for Platform Firmware
Runtime code injection and driver update [1].
The user is expected to provide the EFI capsule, and pass it to the
driver by writing the capsule to a device special file. The capsule
is transferred by the driver to the platform firmware with the help
of an ACPI _DSM method under the special ACPI Platform Firmware
Runtime Update device (INTC1080), and the actual firmware update is
carried out by the low-level Management Mode code in the platform
firmware.
This change allows certain pieces of the platform firmware to be
updated on the fly while the system is running (runtime) without the
need to restart it, which is key in the cases when the system needs to
be available 100% of the time and it cannot afford the downtime related
to restarting it, or when the work carried out by the system is
particularly important, so it cannot be interrupted, and it is not
practical to wait until it is complete.

Rename SSC macros to use generic names instead of PHY specific names,
so that they can be used to specify SSC modes for both Torrent and
Sierra. Renaming the macros should not affect the things as these are
not being used in any DTS file yet.

The QSPI controller on Intel's SoCFPGA platform does not implement the
CQSPI_REG_WR_COMPLETION_CTRL register, thus a write to this register
results in a crash.
Introduce the dts compatible "intel,socfpga-qspi" to differentiate the

Three problems have been revised:
1. CONFIG_PM_OPP no longer depends on CONFIG_PM.
2. opp_find_freq_{ceil, floor} is renamed as dev_pm_opp_find_freq_{ceil,
floor}.
3. Make it clear that the 'opp' struct is actually dev_pm_opp.

This driver implements monitoring and control of fans plugged into the
device. Besides typical speed monitoring and PWM duty cycle control,
voltage and current are reported for every fan.
The device also has 2 connectors for RGB LEDs, support for them isn't
implemented (mainly because there is no standardized sysfs interface).
Also, the device has a noise sensor, but the sensor seems to be completely
useless (and very imprecise), so support for it isn't implemented too.
The driver coexists with userspace tools that access the device through
hidraw interface with no known issues.
The driver has been tested on x86_64, built in and as a module.
Some changes/improvements were suggested by Jonas Malaco.

Linux HWMON sensors driver for ASUS motherboards to read
sensors from the embedded controller.
Many ASUS motherboards do not publish all the available
sensors via the Super I/O chip but the missing ones are
available through the embedded controller (EC) registers.
This driver implements reading those sensor data via the
WMI method BREC, which is known to be present in all ASUS
motherboards based on the AMD 500 series chipsets (and
probably is available in other models too). The driver
needs to know exact register addresses for the sensors and
thus support for each motherboard has to be added explicitly.
The EC registers do not provide critical values for the
sensors and as such they are not published to the HWMON.
Supported motherboards:
* PRIME X570-PRO
* Pro WS X570-ACE
* ROG CROSSHAIR VIII HERO
* ROG CROSSHAIR VIII DARK HERO
* ROG CROSSHAIR VIII FORMULA
* ROG STRIX X570-E GAMING
* ROG STRIX B550-I GAMING
* ROG STRIX B550-E GAMING
