This pattern is common for simple displays, and the DRM core already

drm/bridge: add list of removed refcounted bridges
Between drm_bridge_add() and drm_bridge_remove() bridges are registered to
the DRM core via the global bridge_list and visible in
/sys/kernel/debug/dri/bridges. However between drm_bridge_remove() and the
last drm_bridge_put() memory is still allocated even though the bridge is
not registered, i.e. not in bridges_list, and also not visible in
debugfs. This prevents debugging refcounted bridges lifetime, especially
leaks due to a missing drm_bridge_put().
In order to allow debugfs to also show the removed bridges, move such
bridges into a new ad-hoc list until they are eventually freed.
Note this requires adding INIT_LIST_HEAD(&bridge->list) in the bridge
initialization code. The lack of such init was not exposing any bug so far,
but it would with the new code, for example when a bridge is allocated and
then freed without calling drm_bridge_add(), which is common on probe
errors.
drm_bridge_add() needs special care for bridges being added after having
been previously added and then removed. This happens for example for many
non-DCS DSI host bridge drivers like samsung-dsim which
drm_bridge_add/remove() themselves every time the DSI device does a DSI
attaches/detach. When the DSI device is hot-pluggable this happens multiple
times in the lifetime of the DSI host bridge. On every attach after the
first one, drm_bridge_add() finds bridge->list in the removed list, not at
the initialized state as drm_bridge_add() currently expects. Add a
list_del_init() to remove the bridge from the lingering list and bring
bridge->list back to the initialized state.

drm/sysfb: Lookup blit function during atomic check
Some configurations of sysfb outputs require format conversion from
framebuffer to scanout buffer. It is a driver bug if the conversion
helper is missing, yet it might happen on odd scanout formats. The old
code, based on drm_fb_blit(), only detects this situation during the
commit's hardware update, which is too late to abort the update.
Lookup the correct blit helper as part of the check phase. Then store
it in the sysfb plane state. Allows for detection of a missing helper
before the commit has started. Also avoids drm_fb_blit()'s large switch
statement on each updated scanline. Only a single lookup has to be done.
The lookup is in drm_sysfb_get_blit_func(), which only tracks formats
supported by sysfb drivers.
The lookup happens in sysfb's begin_fb_access helper instead of its
atomic_check helper. This allows vesadrm, and possibly other drivers,
to implement their own atomic_check without interfering with blit
lookups. Vesadrm implements XRGB8888 on top of R8 formats with the
help of the atomic_check. Doing the blit lookup in begin_fb_access then
always uses the correct CRTC format on all drivers.

drm/panfrost: Introduce JM contexts for manging job resources
A JM context describes user-requested priorities for the JM queues.
Context creation leads to the initialization of scheduling entities of
the same priority for all the device's job slots.
Until context creation and destruction are exposed to UM, all issued
jobs shall be bound to the default Panfrost file context, which has
medium priority.

accel/ivpu: Add support for user-managed preemption buffer
Allow user mode drivers to manage preemption buffers, enabling
memory savings by sharing a single buffer across multiple
command queues within the same memory context.
Introduce DRM_IVPU_PARAM_PREEMPT_BUFFER_SIZE to report the required
preemption buffer size as specified by the firmware.
The preemption buffer is now passed from user space as an entry
in the BO list of DRM_IVPU_CMDQ_SUBMIT. The buffer must be
non-mappable and large enough to hold preemption data.
For backward compatibility, the kernel will allocate an internal
preemption buffer if user space does not provide one.
User space can only provide a single preemption buffer,
simplifying the ioctl interface and parameter validation.
A separate secondary preemption buffer is only needed
to save below 4GB address space on 37xx and only if preemption
buffers are not shared.

drm/gem/shmem: Extract drm_gem_shmem_release() from drm_gem_shmem_free()
At the moment, the way that we currently free gem shmem objects is not
ideal for rust bindings. drm_gem_shmem_free() releases all of the
associated memory with a gem shmem object with kfree(), which means that
for us to correctly release a gem shmem object in rust we have to manually
drop all of the contents of our gem object structure in-place by hand
before finally calling drm_gem_shmem_free() to release the shmem resources
and the allocation for the gem object.
Since the only reason this is an issue is because of drm_gem_shmem_free()
calling kfree(), we can fix this by splitting drm_gem_shmem_free() out into
itself and drm_gem_shmem_release(), where drm_gem_shmem_release() releases
the various gem shmem resources without freeing the structure itself. With
this, we can safely re-acquire the KBox for the gem object's memory
allocation and let rust handle cleaning up all of the other struct members
automatically.

drm/gem/shmem: Extract drm_gem_shmem_init() from drm_gem_shmem_create()
With gem objects in rust, the most ideal way for us to be able to handle
gem shmem object creation is to be able to handle the memory allocation of
a gem object ourselves - and then have the DRM gem shmem helpers initialize
the object we've allocated afterwards. So, let's split out
drm_gem_shmem_init() from drm_gem_shmem_create() to allow for doing this.
