53b67da5f0 dt-bindings: gpu: mali-bifrost: Add compatible for RZ/G3L SoC
Add a compatible string for the Renesas RZ/G3L SoC variants that include a
Mali-G31 GPU. These variants share the same restrictions on interrupts,
clocks, and power domains as the RZ/G2L SoC, so extend the existing schema
validation accordingly.

971a6d5d41 drm/bridge: synopsys: dw-dp: Drop useless memory allocation
The bridge gets allocated and initialized implicitly via the
devm_drm_bridge_alloc() helper in dw_dp_bind().  However, this is
preceded by an explicit allocation for the same dw_dp struct, which is
never used anywhere as the return from devm_kzalloc() gets immediately
overwritten by the aforementioned helper.

Get rid of the unnecessary and confusing memory allocation.

9456381d8b drm/rockchip: dw_dp: Fix null-ptr-deref in dw_dp_remove()
Attempting to access driver data in the platform driver ->remove()
callback may lead to a null pointer dereference since there is no
guaranty that the component ->bind() callback invoking
platform_set_drvdata() was executed.

A common scenario is when Rockchip DRM driver didn't manage to run
component_bind_all() because of an (unrelated) error causing early
return from rockchip_drm_bind().

Drop the unnecessary call to platform_get_drvdata() and, instead,
reference the target device structure via platform_device.

ed9da8d230 drm/rockchip: dw_dp: Switch to drmm_kzalloc()
Driver makes use of drmm_encoder_init() to initialize the encoder and
automatically handle the cleanup by registering drm_encoder_cleanup()
with drmm_add_action().

However, the internal structure containing the encoder part gets
allocated with devm_kzalloc(), which happens while component_bind_all()
is being called from Rockchip DRM driver.  The component framework
further ensures it is deallocated as part of releasing all the resources
claimed during bind, which is triggered from component_unbind_all().

When the reference to the DRM device gets eventually dropped via
drm_dev_put() in rockchip_drm_unbind(), drmm_encoder_alloc_release()
attempts to access the now released encoder structure, leading to
use-after-free.

Ensure driver's internal structure is still reachable on encoder cleanup
by switching from a device-managed allocation to a drm-managed one.

enforcing the correct suspend/resume ordering with device links.

of the code.

Since DRM_PANEL_ILITEK_ILI9806E is not used in any in-tree defconfig,
the symbol is renamed directly to DRM_PANEL_ILITEK_ILI9806E_DSI without
providing a legacy compatibility alias.

e3eb0e7081 drm/gem-dma: set VM_DONTDUMP for mmap
When the mmap function was converted from a file op to a GEM object
function in commit f5ca8eb6f9 ("drm/cma-helper: Implement mmap as GEM
CMA object functions") some VM flags were not lifted from drm_gem_mmap():

  - VM_IO
  - VM_DONTEXPAND
  - VM_DONTDUMP

VM_DONTEXPAND was added back in commit 59f39bfa65 ("drm/cma-helper:
Set VM_DONTEXPAND for mmap"). VM_IO doesn't make sense since these are
memory buffers, while "IO tells people not to look at these pages
(accesses can have side effects)".

Add back VM_DONTDUMP. This matches the behavior of most other GEM
implementations.

1f513a3ec3 accel/amdxdna: Add per-process BO memory usage query support
Add support for querying per-process buffer object (BO) memory
usage through the amdxdna GET_ARRAY UAPI.

Introduce a new query type, DRM_AMDXDNA_BO_USAGE, along with
struct amdxdna_drm_bo_usage to report BO memory usage statistics,
including heap, total, and internal usage.

Track BO memory usage on a per-client basis by maintaining counters
in GEM open/close and heap allocation/free paths. This ensures the
reported statistics reflect the current memory footprint of each
process.

Wire the new query into the GET_ARRAY implementation to expose
the usage information to userspace.

9886005f89 drm/simple-kms: Deprecate simple-kms helpers
Deprecate simple-encoder and simple-display-pipe helpers in favor of
regular atomic helpers. Remove the related documentation. Add TODO
item for converting the remaining drivers.

These helpers have been deprecated for years and many drivers have
been updated to not use them. Still there are a few left and we
occasionally receive new drivers build upon them. Marking them as
deprecated will hopefully resolve these problems. The TODO items
should be easy enough for getting new voluteers started on DRM driver
development.
