FB_DAMAGE_CLIPS is an optional plane property to mark damaged regions
on the plane in framebuffer coordinates of the framebuffer attached to
the plane.
The layout of blob data is simply an array of "struct drm_mode_rect".
Unlike plane src coordinates, damage clips are not in 16.16 fixed point.
As plane src in framebuffer cannot be negative so are damage clips. In
damage clip, x1/y1 are inclusive and x2/y2 are exclusive.
This patch also exports the kernel internal drm_rect to userspace as
drm_mode_rect. This is because "struct drm_clip_rect" is not sufficient
to represent damage for current plane size.
Driver which are interested in enabling FB_DAMAGE_CLIPS property for a
plane should enable this property using drm_plane_enable_damage_clips.
v2:
- Input validation on damage clips against framebuffer size.
- Doc update, other minor changes.

drm/imx: update image-convert with fixes for multi-tiled scaling
Update the ipu-v3 mem2mem image-convert code, with some fixes for race
conditions, alignment issues, and visual artifacts due to tile alignment
and scaling factor issues when scaling images larger than hardware
limitations in multiple tiles. This will allow the V4L2 mem2mem scaler
driver to write output images larger than 1024x1024 pixels.
Also switch drm/imx source files to SPDX license identifiers, constify
struct clk_ops in imx-tve, and add a timeout warning to the busy wait in
ipu_plane_disable().

[Why]
New GCC warnings for stringop-truncation and stringop-overflow help
catch common misuse of strncpy. This patch suppresses these warnings
by fixing bugs identified by them.
[How]
Since the parameter passed for name in amdpgu_dm_create_common_mode has
no fixed length, if the string is >= DRM_DISPLAY_MODE_LEN then
mode->name will not be null-terminated.
The truncation in fill_audio_info won't actually occur (and the string
will be null-terminated since the buffer is initialized to zero), but
the warning can be suppressed by using the proper buffer size.
This patch fixes both issues by using the real size for the buffer and
making use of strscpy (which always terminates).

Currently we allocate a scratch page for each engine, but since we only
ever write into it for post-sync operations, it is not exposed to
userspace nor do we care for coherency. As we then do not care about its
contents, we can use one page for all, reducing our allocations and
avoid complications by not assuming per-engine isolation.
For later use, it simplifies engine initialisation (by removing the
allocation that required struct_mutex!) and means that we can always rely
on there being a scratch page.

We stopped re-applying the GT workarounds after engine reset since commit
59b449d5c82a ("drm/i915: Split out functions for different kinds of
workarounds").
Issue with this is that some of the GT workarounds live in the MMIO space
which gets lost during engine resets. So far the registers in 0x2xxx and
0xbxxx address range have been identified to be affected.
This losing of applied workarounds has obvious negative effects and can
even lead to hard system hangs (see the linked Bugzilla).
Rather than just restoring this re-application, because we have also
observed that it is not safe to just re-write all GT workarounds after
engine resets (GPU might be live and weird hardware states can happen),
we introduce a new class of per-engine workarounds and move only the
affected GT workarounds over.
Using the framework introduced in the previous patch, we therefore after
engine reset, re-apply only the workarounds living in the affected MMIO
address ranges.

To enable later verification of GT workaround state at various stages of
driver lifetime, we record the list of applicable ones per platforms to a
list, from which they are also applied.
The added data structure is a simple array of register, mask and value
items, which is allocated on demand as workarounds are added to the list.
This is a temporary implementation which later in the series gets fused
with the existing per context workaround list handling. It is separated at
this stage since the following patch fixes a bug which needs to be as easy
to backport as possible.
Also, since in the following patch we will be adding a new class of
workarounds (per engine) which can be applied from interrupt context, we
straight away make the provision for safe read-modify-write cycle.

As DMA code is the only user of IOMMU code both files can be merged.
It allows to remove stub functions, after slight adjustment of
exynos_drm_register_dma. Since IOMMU functions are used locally they
can be marked static.

Exynos DRM drivers should work with and without IOMMU. Providing common
API generic to both scenarios should make code cleaner and allow further
code improvements.
The patch removes including of exynos_drm_iommu.h as the file contains
mostly IOMMU specific stuff, instead it exposes exynos_drm_*_dma functions
and puts them into exynos_drm_dma.c.

The core scheduler tells us when the job is pushed to the scheduler's
queue, and I had the job_run functions saying when they actually queue
the job to the hardware. By adding tracepoints for the very top of
the ioctls and the IRQs signaling job completion, "perf record -a -e
v3d:.\* -e gpu_scheduler:.\* <job>; perf script" gets you a pretty
decent timeline.
