Pull missed media updates from Mauro Carvalho Chehab:
 "It seems I screwed-up my previous pull request: it ends up that only
  half of the media patches that were in linux-next got merged in -rc1.

  The script which creates the signed tags silently failed due to
  5.19->6.0 so it ended generating a tag with incomplete stuff.

  So here are the missing parts:

   - a DVB core security fix

   - lots of fixes and cleanups for atomisp staging driver

   - old drivers that are VB1 are being moved to staging to be
     deprecated

   - several driver updates - mostly for embedded systems, but there are
     also some things addressing issues with some PC webcams, in the UVC
     video driver"

Pull more random number generator updates from Jason Donenfeld:
 "This time with some large scale treewide cleanups.

  The intent of this pull is to clean up the way callers fetch random
  integers. The current rules for doing this right are:

   - If you want a secure or an insecure random u64, use get_random_u64()

   - If you want a secure or an insecure random u32, use get_random_u32()

     The old function prandom_u32() has been deprecated for a while
     now and is just a wrapper around get_random_u32(). Same for
     get_random_int().

   - If you want a secure or an insecure random u16, use get_random_u16()

   - If you want a secure or an insecure random u8, use get_random_u8()

   - If you want secure or insecure random bytes, use get_random_bytes().

     The old function prandom_bytes() has been deprecated for a while
     now and has long been a wrapper around get_random_bytes()

   - If you want a non-uniform random u32, u16, or u8 bounded by a
     certain open interval maximum, use prandom_u32_max()

     I say "non-uniform", because it doesn't do any rejection sampling
     or divisions. Hence, it stays within the prandom_*() namespace, not
     the get_random_*() namespace.

     I'm currently investigating a "uniform" function for 6.2. We'll see
     what comes of that.

  By applying these rules uniformly, we get several benefits:

   - By using prandom_u32_max() with an upper-bound that the compiler
     can prove at compile-time is ≤65536 or ≤256, internally
     get_random_u16() or get_random_u8() is used, which wastes fewer
     batched random bytes, and hence has higher throughput.

   - By using prandom_u32_max() instead of %, when the upper-bound is
     not a constant, division is still avoided, because
     prandom_u32_max() uses a faster multiplication-based trick instead.

   - By using get_random_u16() or get_random_u8() in cases where the
     return value is intended to indeed be a u16 or a u8, we waste fewer
     batched random bytes, and hence have higher throughput.

  This series was originally done by hand while I was on an airplane
  without Internet. Later, Kees and I worked on retroactively figuring
  out what could be done with Coccinelle and what had to be done
  manually, and then we split things up based on that.

  So while this touches a lot of files, the actual amount of code that's
  hand fiddled is comfortably small"

1b5964b2f9 Merge patch series "Fix dt-validate issues on qemu dtbdumps due to dt-bindings"
Conor Dooley <mail@conchuod.ie> says:

From: Conor Dooley <conor.dooley@microchip.com>

The device trees produced automatically for the virt and spike machines
fail dt-validate on several grounds. Some of these need to be fixed in
the linux kernel's dt-bindings, but others are caused by bugs in QEMU.

Patches been sent that fix the QEMU issues [0], but a couple of them
need to be fixed in the kernel's dt-bindings. The first patches add
compatibles for "riscv,{clint,plic}0" which are present in drivers and
the auto generated QEMU dtbs.

Thanks to Rob Herring for reporting these issues [1],
Conor.

To reproduce the errors:
./build/qemu-system-riscv64 -nographic -machine virt,dumpdtb=qemu.dtb
dt-validate -p /path/to/linux/kernel/Documentation/devicetree/bindings/processed-schema.json qemu.dtb

299824e68b dt-bindings: riscv: add new riscv,isa strings for emulators
The QEMU virt and spike machines currently export a riscv,isa string of
"rv64imafdcsuh",

While the RISC-V foundation has been ratifying a bunch of extenstions
etc, the kernel has remained relatively static with what hardware is
supported - but the same is not true of QEMU. Using the virt machine
and running dt-validate on the dumped dtb fails, partly due to the
unexpected isa string.

Rather than enumerate the many many possbilities, change the pattern
to a regex, with the following assumptions:
- ima are required
- the single letter order is fixed & we don't care about things that
  can't even do "ima"
- the standard multi letter extensions are all in a "_z<foo>" format
  where the first letter of <foo> is a valid single letter extension
- _s & _h are used for supervisor and hyper visor extensions
- convention says that after the first two chars, a standard multi
  letter extension name could be an english word (ifencei anyone?) so
  it's not worth restricting the charset
- as the above is just convention, don't apply any charset restrictions
  to reduce future churn
- vendor ISA extensions begind with _x and have no charset restrictions
- we don't care about an e extension from an OS pov
- that attempting to validate the contents of the multiletter extensions
  with dt-validate beyond the formatting is a futile, massively verbose
  or unwieldy exercise at best

The following limitations also apply:
- multi letter extension ordering is not enforced. dt-schema does not
  appear to allow for named match groups, so the resulting regex would
  be even more of a headache
- ditto for the numbered extensions

Finally, add me as a maintainer of the binding so that when it breaks
in the future, I can be held responsible!

Microchip RISC-V devicetrees for v6.1

Fixups, reference design changes and new boards:
- The addition of QSPI support for mpfs had a corresponding change to
  the devicetree node.
- The v2022.{09,10} reference designs brought with them several memory
  map changes which are not backwards compatible. The old devicetrees
  from the v2022.08 and earlier releases still work with current
  kernels.
- Two new devicetrees for a first-party development kit and for the
  Aries Embedded M100FPSEVP kit.
- Corresponding dt-bindings changes for the above.

Pull VFIO updates from Alex Williamson:

 - Prune private items from vfio_pci_core.h to a new internal header,
   fix missed function rename, and refactor vfio-pci interrupt defines
   (Jason Gunthorpe)

 - Create consistent naming and handling of ioctls with a function per
   ioctl for vfio-pci and vfio group handling, use proper type args
   where available (Jason Gunthorpe)

 - Implement a set of low power device feature ioctls allowing userspace
   to make use of power states such as D3cold where supported (Abhishek
   Sahu)

 - Remove device counter on vfio groups, which had restricted the page
   pinning interface to singleton groups to account for limitations in
   the type1 IOMMU backend. Document usage as limited to emulated IOMMU
   devices, ie. traditional mdev devices where this restriction is
   consistent (Jason Gunthorpe)

 - Correct function prefix in hisi_acc driver incurred during previous
   refactoring (Shameer Kolothum)

 - Correct typo and remove redundant warning triggers in vfio-fsl driver
   (Christophe JAILLET)

 - Introduce device level DMA dirty tracking uAPI and implementation in
   the mlx5 variant driver (Yishai Hadas & Joao Martins)

 - Move much of the vfio_device life cycle management into vfio core,
   simplifying and avoiding duplication across drivers. This also
   facilitates adding a struct device to vfio_device which begins the
   introduction of device rather than group level user support and fills
   a gap allowing userspace identify devices as vfio capable without
   implicit knowledge of the driver (Kevin Tian & Yi Liu)

 - Split vfio container handling to a separate file, creating a more
   well defined API between the core and container code, masking IOMMU
   backend implementation from the core, allowing for an easier future
   transition to an iommufd based implementation of the same (Jason
   Gunthorpe)

 - Attempt to resolve race accessing the iommu_group for a device
   between vfio releasing DMA ownership and removal of the device from
   the IOMMU driver. Follow-up with support to allow vfio_group to exist
   with NULL iommu_group pointer to support existing userspace use cases
   of holding the group file open (Jason Gunthorpe)

 - Fix error code and hi/lo register manipulation issues in the hisi_acc
   variant driver, along with various code cleanups (Longfang Liu)

 - Fix a prior regression in GVT-g group teardown, resulting in
   unreleased resources (Jason Gunthorpe)

 - A significant cleanup and simplification of the mdev interface,
   consolidating much of the open coded per driver sysfs interface
   support into the mdev core (Christoph Hellwig)

 - Simplification of tracking and locking around vfio_groups that fall
   out from previous refactoring (Jason Gunthorpe)

 - Replace trivial open coded f_ops tests with new helper (Alex
   Williamson)

06267eb2de doc: RISC-V: Document that misaligned accesses are supported
The RISC-V ISA manual used to mandate that misaligned accesses were
supported in user mode, but that requirement was removed in 2018 via
riscv-isa-manual commit 61cadb9 ("Provide new description of misaligned
load/store behavior compatible with privileged architecture.").  Since
the Linux uABI was already frozen at that point it's just been demoted
to part of the uABI, but that was never written down.
