Pull documentation updates from Jonathan Corbet:
"It has been a relatively busy cycle in docsland, with changes all
over:
- Bring the kernel memory-model docs into the Sphinx build in the
"literal include" mode.
- Lots of build-infrastructure work, further cleaning up long-term
kernel-doc technical debt. The sphinx-pre-install tool has been
converted to Python and updated for current systems.
- A new tool to detect when documents have been moved and generate
HTML redirects; this can be used on kernel.org (or any other site
hosting the rendered docs) to avoid breaking links.
- Automated processing of the YAML files describing the netlink
protocol.
- A significant update of the maintainer's PGP guide.
... and a seemingly endless series of typo fixes, build-problem fixes,
etc"

The UVC driver provides two metadata types V4L2_META_FMT_UVC, and
V4L2_META_FMT_D4XX. The only difference between the two of them is that
V4L2_META_FMT_UVC only copies PTS, SCR, size and flags, and
V4L2_META_FMT_D4XX copies the whole metadata section.
Now we only enable V4L2_META_FMT_D4XX for the Intel D4xx family of
devices, but it is useful to have the whole metadata payload for any
device where vendors include other metadata, such as the one described by
Microsoft:
https://learn.microsoft.com/en-us/windows-hardware/drivers/stream/mf-capture-metadata
This patch introduces a new format V4L2_META_FMT_UVC_MSXU_1_5, that is
identical to V4L2_META_FMT_D4XX.
Let the user enable this format with a quirk for now. This way they can
test if their devices provide useful metadata without rebuilding the
kernel. They can later contribute patches to auto-quirk their devices.
We will also work in methods to auto-detect devices compatible with this
new metadata format.

The documentation currently describes the UVC length field as the "length
of the rest of the block", which can be misleading. The driver limits the
data copied to a maximum of 12 bytes.
This change adds a clarifying sentence to the documentation to make this
restriction explicit.

The Renesas Camera Receiver Unit in the RZ/V2H SoC can output RAW
data captured from an image sensor without conversion to an RGB/YUV
format. In that case the data are packed into 64-bit blocks, with a
variable amount of padding in the most significant bits depending on
the bitdepth of the data. Add new V4L2 pixel format codes for the new
formats, along with documentation to describe them.

Add NV15 and NV20 pixel formats used by the Rockchip Video Decoder for
10-bit buffers.
NV15 and NV20 is 10-bit 4:2:0/4:2:2 semi-planar YUV formats similar to
NV12 and NV16, using 10-bit components with no padding between each
component. Instead, a group of 4 luminance/chrominance samples are
stored over 5 bytes in little endian order:
YYYY = UVUV = 4 * 10 bits = 40 bits = 5 bytes
The '15' and '20' suffix refers to the optimum effective bits per pixel
which is achieved when the total number of luminance samples is a
multiple of 8 for NV15 and 4 for NV20.

Document V4L2_PIX_FMT_MT2110T and V4L2_PIX_FMT_MT2110R. These two
formats are nearly identical, reusing MM21 format and expending it
by inserting chunk of 16 bytes of lower 2 bit pixel data after each
chunk of 64 bytes higher 8 bit of data.

The rkisp1 driver stores ISP configuration parameters in the fixed
rkisp1_params_cfg structure. As the members of the structure are part of
the userspace API, the structure layout is immutable and cannot be
extended further. Introducing new parameters or modifying the existing
ones would change the buffer layout and cause breakages in existing
applications.
The allow for future extensions to the ISP parameters, introduce a new
extensible parameters format, with a new format 4CC. Document usage of
the new format in the rkisp1 admin guide.

The documentation of the Memory Consistency Flags was part of the struct
v4l2_buffer documentation, but that struct doesn't use those flags. Instead
it is used by VIDIOC_CREATE_BUFS and VIDIOC_REQBUFS. Move the documentation
from buffer.rst to vidioc-reqbufs.rst which is where it belongs.

If this flag is set, then the reply is expected to consist of
the CEC_MSG_VENDOR_COMMAND_WITH_ID opcode followed by the Vendor ID (as
used in bytes 1-4 of the message), followed by the struct cec_msg reply
field.
Note that this assumes that the byte after the Vendor ID is a
vendor-specific opcode.
This flag makes it easier to wait for replies to vendor commands,
using the same CEC framework support for waiting for regular replies.
Support for this flag is indicated by setting the new
CEC_CAP_REPLY_VENDOR_ID capability.

The original patch added two columns in the flat-table of Luma-Only
Image Formats, without updating hints to latex: above it. This results
in wrong column count in the output of Sphinx's latex builder.
