Pull driver core updates from Greg KH:
 "Here is the big set of driver core changes for 6.11-rc1.

  Lots of stuff in here, with not a huge diffstat, but apis are evolving
  which required lots of files to be touched. Highlights of the changes
  in here are:

   - platform remove callback api final fixups (Uwe took many releases
     to get here, finally!)

   - Rust bindings for basic firmware apis and initial driver-core
     interactions.

     It's not all that useful for a "write a whole driver in rust" type
     of thing, but the firmware bindings do help out the phy rust
     drivers, and the driver core bindings give a solid base on which
     others can start their work.

     There is still a long way to go here before we have a multitude of
     rust drivers being added, but it's a great first step.

   - driver core const api changes.

     This reached across all bus types, and there are some fix-ups for
     some not-common bus types that linux-next and 0-day testing shook
     out.

     This work is being done to help make the rust bindings more safe,
     as well as the C code, moving toward the end-goal of allowing us to
     put driver structures into read-only memory. We aren't there yet,
     but are getting closer.

   - minor devres cleanups and fixes found by code inspection

   - arch_topology minor changes

   - other minor driver core cleanups

  All of these have been in linux-next for a very long time with no
  reported problems"

<title>gpu: ipu-v3: pre: don't use fixed timeout when waiting for safe window</title>

<content type='text'>
The timeout when waiting for the PRE safe window is rather short, as
normally we would only need to wait a few dozen usecs for the problematic
scanline region to pass and we don't want to spin too long in case
something goes wrong. This however mixes badly with preemption, as we
can easily get scheduled away from the CPU for a longer time than our
timeout, in which case we would hit a spurious timeout and wrongly skip
the PRE update.

Instead of disabling preemption across the wait loop, potentially
impacting the overall system latency, use a wait loop with a fixed
max number of iterations, so time spent away from the CPU is not
accounted against the timeout budget.

imx-drm doesn't mandate a modeset when the framebuffer modifier changes,
but currently the tile prefetch and resolve (TPR) configuration of the
PRE is only set up on the initial modeset.

As the TPR configuration is double buffered, same as all the other PRE
states, we can support dynamic reconfiguration of the buffer layout from
one frame to another. As switching between (super-)tiled and linear
prefetch needs to touch the CTRL register make sure to do the
reconfiguration inside the safe window.

<title>gpu: ipu-v3: Convert to platform remove callback returning void</title>

<content type='text'>
The .remove() callback for a platform driver returns an int which makes
many driver authors wrongly assume it's possible to do error handling by
returning an error code. However the value returned is ignored (apart
from emitting a warning) and this typically results in resource leaks.

To improve here there is a quest to make the remove callback return
void. In the first step of this quest all drivers are converted to
.remove_new(), which already returns void. Eventually after all drivers
are converted, .remove_new() will be renamed to .remove().

Trivially convert the ipu-v3 platform drivers from always returning zero
in the remove callback to the void returning variant.

Pull drm updates from Dave Airlie:
 "The drm core grew a new generic gpu virtual address manager, and new
  execution locking helpers. These are used by nouveau now to provide
  uAPI support for the userspace Vulkan driver. AMD had a bunch of new
  IP core support, loads of refactoring around fbdev, but mostly just
  the usual amount of stuff across the board.

  core:
   - fix gfp flags in drmm_kmalloc

  fbdev:
   - make fbdev userspace interfaces optional
   - use linux device instead of fbdev device
   - use deferred i/o helper macros in various drivers
   - Make FB core selectable without drivers
