'enum' is equivalent to 'oneOf' with a list of 'const' entries, but 'enum'
is more concise and yields better error messages.
Fix a couple more cases which have appeared.

Pull habanalabs updates from Greg KH:
"Here is another round of misc driver patches for 5.15-rc1.
In here is only updates for the Habanalabs driver. This request is
late because the previously-objected-to dma-buf patches are all
removed and some fixes that you and others found are now included in
here as well.
All of these have been in linux-next for well over a week with no
reports of problems, and they are all self-contained to only this one
driver. Full details are in the shortlog"

Pull more power management updates from Rafael Wysocki:
"These are mostly ARM cpufreq driver updates, including one new
MediaTek driver that has just passed all of the reviews, with the
addition of a revert of a recent intel_pstate commit, some core
cpufreq changes and a DT-related update of the operating performance
points (OPP) support code.
Specifics:
- Add new cpufreq driver for the MediaTek MT6779 platform called
mediatek-hw along with corresponding DT bindings (Hector.Yuan).
- Add DCVS interrupt support to the qcom-cpufreq-hw driver (Thara
Gopinath).
- Make the qcom-cpufreq-hw driver set the dvfs_possible_from_any_cpu
policy flag (Taniya Das).
- Blocklist more Qualcomm platforms in cpufreq-dt-platdev (Bjorn
Andersson).
- Make the vexpress cpufreq driver set the CPUFREQ_IS_COOLING_DEV
flag (Viresh Kumar).
- Add new cpufreq driver callback to allow drivers to register with
the Energy Model in a consistent way and make several drivers use
it (Viresh Kumar).
- Change the remaining users of the .ready() cpufreq driver callback
to move the code from it elsewhere and drop it from the cpufreq
core (Viresh Kumar).
- Revert recent intel_pstate change adding HWP guaranteed performance
change notification support to it that led to problems, because the
notification in question is triggered prematurely on some systems
(Rafael Wysocki).
- Convert the OPP DT bindings to DT schema and clean them up while at
it (Rob Herring)"

The memory hot(un)plug documentation is outdated and incomplete. Most of
the content dates back to 2007, so it's time for a major overhaul.
Let's rewrite, reorganize and update most parts of the documentation. In
addition to memory hot(un)plug, also add some details regarding
ZONE_MOVABLE, with memory hotunplug being one of its main consumers.
Drop the file history, that information can more reliably be had from the
git log.
The style of the document is also properly fixed that e.g., "restview"
renders it cleanly now.
In the future, we might add some more details about virt users like
virtio-mem, the XEN balloon, the Hyper-V balloon and ppc64 dlpar.

Patch series "memory-hotplug.rst: complete admin-guide overhaul", v3.
This patch (of 2):
We have the same content at Documentation/core-api/memory-hotplug.rst and
it doesn't fit into the admin-guide. The documentation was accidentially
duplicated when merging.

VDUSE (vDPA Device in Userspace) is a framework to support
implementing software-emulated vDPA devices in userspace. This
document is intended to clarify the VDUSE design and usage.

This VDUSE driver enables implementing software-emulated vDPA
devices in userspace. The vDPA device is created by
ioctl(VDUSE_CREATE_DEV) on /dev/vduse/control. Then a char device
interface (/dev/vduse/$NAME) is exported to userspace for device
emulation.
In order to make the device emulation more secure, the device's
control path is handled in kernel. A message mechnism is introduced
to forward some dataplane related control messages to userspace.
And in the data path, the DMA buffer will be mapped into userspace
address space through different ways depending on the vDPA bus to
which the vDPA device is attached. In virtio-vdpa case, the MMU-based
software IOTLB is used to achieve that. And in vhost-vdpa case, the
DMA buffer is reside in a userspace memory region which can be shared
to the VDUSE userspace processs via transferring the shmfd.
For more details on VDUSE design and usage, please see the follow-on
Documentation commit.
NB(mst): when merging this with
b542e383d8c0 ("eventfd: Make signal recursion protection a task bit")
replace eventfd_signal_count with eventfd_signal_allowed,
and drop the previous
("eventfd: Export eventfd_wake_count to modules").

CRU is a block used in e.g. Northstar devices. It can be seen in the
bcm5301x.dtsi and this binding documents its proper usage.

Allow virtio device sub-nodes to be added to the virtio mmio or pci
nodes. The compatible property for virtio device must be of the format
"virtio,device<ID>", where ID is virtio device ID in hexadecimal format.
