9a758d8756 drm: Move nomodeset kernel parameter to drivers/video
Move the nomodeset kernel parameter to drivers/video to make it
available to non-DRM drivers. Adapt the interface, but keep the DRM
interface drm_firmware_drivers_only() to avoid churn within DRM. The
function should later be inlined into callers.

The parameter disables any DRM graphics driver that would replace a
driver for firmware-provided scanout buffers. It is an option to easily
fallback to basic graphics output if the hardware's native driver is
broken. Moving it to a more prominent location wil make it available
to fbdev as well.

v2:
	* clarify the meaning of the nomodeset parameter (Javier)

ee71434eeb drm/i915/mtl: Handle wopcm per-GT and limit calculations.
With MTL standalone media architecture the wopcm layout has changed,
with separate partitioning in WOPCM for the root GT GuC and the media
GT GuC. The size of WOPCM is 4MB with the lower 2MB reserved for the
media GT and the upper 2MB for the root GT.

Given that MTL has GuC deprivilege, the WOPCM registers are pre-locked
by the bios. Therefore, we can skip all the math for the partitioning
and just limit ourselves to sanity-checking the values.

v2: fix makefile file ordering (Jani)
v3: drop XELPM_SAMEDIA_WOPCM_SIZE, check huc instead of VDBOX (John)
v4: further clarify commit message, remove blank line (John)

dt-bindings: display: sun6i-dsi: Add the A100 variant
The "40nm" MIPI DSI controller found in the A100 and D1 SoCs has the
same register layout as previous SoC integrations. However, its module
clock now comes from the TCON, which means it no longer runs at a fixed
rate, so this needs to be distinguished in the driver.

The controller also now uses pins on Port D instead of dedicated pins,
so it drops the separate power domain.

Merge tag 'media/v6.1-2' of git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-media

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"

4c2572fe0a drm/i915/hwmon: Expose power1_max_interval
Expose power1_max_interval, that is the tau corresponding to PL1, as a

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"

83439a0f1c Documentation: ACPI: Prune DSDT override documentation from index
Commit d206cef03c ("ACPI: docs: Drop useless DSDT override documentation")
removes useless DSDT override documentation. However, the commit forgets
to prune the documentation entry from table of contents of ACPI admin
guide documentation, hence triggers Sphinx warning:

Documentation/admin-guide/acpi/index.rst:8: WARNING: toctree contains reference to nonexisting document 'admin-guide/acpi/dsdt-override'

Prune the entry to fix the warning.

Fixes: d206cef03c ("ACPI: docs: Drop useless DSDT override documentation")
