Pull thermal control updates from Rafael Wysocki:
"As far as new functionality is concerned, there is a new thermal
driver for the Intel Hardware Feedback Interface (HFI) along with some
intel-speed-select utility changes to support it. There are also new
DT compatible strings for a couple of platforms, and thermal zones on
some platforms will be registered as HWmon sensors now.
Apart from the above, some drivers are updated (fixes mostly) and
there is a new piece of documentation for the Intel DPTF (Dynamic
Power and Thermal Framework) sysfs interface.
Specifics:
- Add a new thermal driver for the Intel Hardware Feedback Interface
(HFI) including the HFI initialization, HFI notification interrupt
handling and sending CPU capabilities change messages to user space
via the thermal netlink interface (Ricardo Neri, Srinivas
Pandruvada, Nathan Chancellor, Randy Dunlap).
- Extend the intel-speed-select utility to handle out-of-band CPU
configuration changes and add support for the CPU capabilities
change messages sent over the thermal netlink interface by the new
HFI thermal driver to it (Srinivas Pandruvada).
- Convert the DT bindings to yaml format for the Exynos platform and
fix and update the MAINTAINERS file for this driver (Krzysztof
Kozlowski).
- Register the thermal zones as HWmon sensors for the QCom's Tsens
driver and TI thermal platforms (Dmitry Baryshkov, Romain Naour).
- Add the msm8953 compatible documentation in the bindings (Luca
Weiss).
- Add the sm8150 platform support to the QCom LMh driver's DT binding
(Thara Gopinath).
- Check the command result from the IPC command to the BPMP in the
Tegra driver (Mikko Perttunen).
- Silence the error for normal configuration where the interrupt is
optionnal in the Broadcom thermal driver (Florian Fainelli).
- Remove remaining dead code from the TI thermal driver (Yue
Haibing).
- Don't use bitmap_weight() in end_power_clamp() in the powerclamp
driver (Yury Norov).
- Update the OS policy capabilities handshake in the int340x thermal
driver (Srinivas Pandruvada).
- Increase the policies bitmap size in int340x (Srinivas Pandruvada).
- Replace acpi_bus_get_device() with acpi_fetch_acpi_dev() in the
int340x thermal driver (Rafael Wysocki).
- Check for NULL after calling kmemdup() in int340x (Jiasheng Jiang).
- Add Intel Dynamic Power and Thermal Framework (DPTF) kernel
interface documentation (Srinivas Pandruvada).
- Fix bullet list warning in the thermal documentation (Randy
Dunlap)"

Add sysfs files that expose the inline encryption capabilities of
request queues:
/sys/block/$disk/queue/crypto/max_dun_bits
/sys/block/$disk/queue/crypto/modes/$mode
/sys/block/$disk/queue/crypto/num_keyslots
Userspace can use these new files to decide what encryption settings to
use, or whether to use inline encryption at all. This also brings the
crypto capabilities in line with the other queue properties, which are
already discoverable via the queue directory in sysfs.
Design notes:
- Place the new files in a new subdirectory "crypto" to group them
together and to avoid complicating the main "queue" directory. This
also makes it possible to replace "crypto" with a symlink later if
we ever make the blk_crypto_profiles into real kobjects (see below).
- It was necessary to define a new kobject that corresponds to the
crypto subdirectory. For now, this kobject just contains a pointer
to the blk_crypto_profile. Note that multiple queues (and hence
multiple such kobjects) may refer to the same blk_crypto_profile.
An alternative design would more closely match the current kernel
data structures: the blk_crypto_profile could be a kobject itself,
located directly under the host controller device's kobject, while
/sys/block/$disk/queue/crypto would be a symlink to it.
I decided not to do that for now because it would require a lot more
changes, such as no longer embedding blk_crypto_profile in other
structures, and also because I'm not sure we can rule out moving the
crypto capabilities into 'struct queue_limits' in the future. (Even
if multiple queues share the same crypto engine, maybe the supported
data unit sizes could differ due to other queue properties.) It
would also still be possible to switch to that design later without
breaking userspace, by replacing the directory with a symlink.
- Use "max_dun_bits" instead of "max_dun_bytes". Currently, the
kernel internally stores this value in bytes, but that's an
implementation detail. It probably makes more sense to talk about
this value in bits, and choosing bits is more future-proof.
- "modes" is a sub-subdirectory, since there may be multiple supported
crypto modes, sysfs is supposed to have one value per file, and it
makes sense to group all the mode files together.
- Each mode had to be named. The crypto API names like "xts(aes)" are
not appropriate because they don't specify the key size. Therefore,
I assigned new names. The exact names chosen are arbitrary, but
they happen to match the names used in log messages in fs/crypto/.
- The "num_keyslots" file is a bit different from the others in that
it is only useful to know for performance reasons. However, it's
included as it can still be useful. For example, a user might not
want to use inline encryption if there aren't very many keyslots.

PPIN is the Protected Processor Identification Number.
This is used to identify the socket as a Field Replaceable Unit (FRU).
Existing code only displays this when reporting errors. But this makes
it inconvenient for large clusters to use it for its intended purpose
of inventory control.
Add ppin to /sys/devices/system/cpu/cpu*/topology to make what
is already available using RDMSR more easily accessible. Make
the file read only for root in case there are still people
concerned about making a unique system "serial number" available.

`driver_override` allows to control which of the vDPA bus drivers
binds to a vDPA device.
If `driver_override` is not set, the previous behaviour is followed:
devices use the first vDPA bus driver loaded (unless auto binding
is disabled).
Tested on Fedora 34 with driverctl(8):
$ modprobe virtio-vdpa
$ modprobe vhost-vdpa
$ modprobe vdpa-sim-net
$ vdpa dev add mgmtdev vdpasim_net name dev1
# dev1 is attached to the first vDPA bus driver loaded
$ driverctl -b vdpa list-devices
dev1 virtio_vdpa
$ driverctl -b vdpa set-override dev1 vhost_vdpa
$ driverctl -b vdpa list-devices
dev1 vhost_vdpa [*]
Note: driverctl(8) integrates with udev so the binding is
preserved.

Pull dax and libnvdimm updates from Dan Williams:
"The bulk of this is a rework of the dax_operations API after
discovering the obstacles it posed to the work-in-progress DAX+reflink
support for XFS and other copy-on-write filesystem mechanics.
Primarily the need to plumb a block_device through the API to handle
partition offsets was a sticking point and Christoph untangled that
dependency in addition to other cleanups to make landing the
DAX+reflink support easier.
The DAX_PMEM_COMPAT option has been around for 4 years and not only
are distributions shipping userspace that understand the current
configuration API, but some are not even bothering to turn this option
on anymore, so it seems a good time to remove it per the deprecation
schedule. Recall that this was added after the device-dax subsystem
moved from /sys/class/dax to /sys/bus/dax for its sysfs organization.
All recent functionality depends on /sys/bus/dax.
Some other miscellaneous cleanups and reflink prep patches are
included as well.
Summary:
- Simplify the dax_operations API:
- Eliminate bdev_dax_pgoff() in favor of the filesystem
maintaining and applying a partition offset to all its DAX iomap
operations.
- Remove wrappers and device-mapper stacked callbacks for
->copy_from_iter() and ->copy_to_iter() in favor of moving
block_device relative offset responsibility to the
dax_direct_access() caller.
- Remove the need for an @bdev in filesystem-DAX infrastructure
- Remove unused uio helpers copy_from_iter_flushcache() and
copy_mc_to_iter() as only the non-check_copy_size() versions are
used for DAX.
- Prepare XFS for the pending (next merge window) DAX+reflink support
- Remove deprecated DEV_DAX_PMEM_COMPAT support
- Cleanup a straggling misuse of the GUID api"

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.

2nd set of new device support etc for IIO in the 5.17 cycle.
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.

I2C debugfs support is limited to 1 byte. We extend functionality
to more than 1 byte by using one of the pad fields as a length.
No backward compatibility issues as new F/W versions will treat 0
length as a 1 byte length transaction.

Add a sysfs knob to allow tuning of retries for the kernel ENQCMDS
descriptor submission. While on host, it is not as likely that ENQCMDS
return busy during normal operations due to the driver controlling the
number of descriptors allocated for submission. However, when the driver is
operating as a guest driver, the chance of retry goes up significantly due
to sharing a wq with multiple VMs. A default value is provided with the
system admin being able to tune the value on a per WQ basis.
