Add extras to support i.MX8M Plus. The main change is the removal of
HS/VS/DE signal inversion in the LCDIFv3-DSIM glue logic, otherwise
the implementation of this IP in i.MX8M Plus is very much compatible
with the i.MX8M Mini/Nano one.

Samsung MIPI DSIM controller is common DSI IP that can be used in various
SoCs like Exynos, i.MX8M Mini/Nano.
In order to access this DSI controller between various platform SoCs,
the ideal way to incorporate this in the drm stack is via the drm bridge
driver.
We already have a consolidated code for supporting component and bridge
based DRM drivers, so keep the exynos component based code in existing
exynos_drm_dsi.c and move generic bridge code as part of samsung-dsim.c

This tag contains habanalabs driver and accel changes for v6.4:
- uAPI changes:
- Add opcodes to the CS ioctl to allow user to stall/resume specific engines
inside Gaudi2. This is to allow the user to perform power
testing/measurements when training different topologies.
- Expose in the INFO ioctl the amount of device memory that the driver
and f/w reserve for themselves.
- Expose in the INFO ioctl a bit-mask of the available rotator engines
in Gaudi2. This is to align with other engines that are already exposed.
- Expose in the INFO ioctl the register's address of the f/w that should
be used to trigger interrupts from within the user's code running in the
compute engines.
- Add a critical-event bit in the eventfd bitmask so the user will know the
event that was received was critical, and a reset will now occur
- Expose in the INFO ioctl two new opcodes to fetch information on h/w and
f/w events. The events recorded are the events that were reported in the
eventfd.
- New features and improvements:
- Add a dedicated interrupt ID in MSI-X in the device to the notification of
an unexpected user-related event in Gaudi2. Handle it in the driver by
reporting this event.
- Allow the user to fetch the device memory current usage even when the
device is undergoing compute-reset (a reset type that only clears the
compute engines).
- Enable graceful reset mechanism for compute-reset. This will give the
user a few seconds before the device is reset. For example, the user can,
during that time, perform certain device operations (dump data for debug)
or close the device in an orderly fashion.
- Align the decoder with the rest of the engines in regard to notification
to the user about interrupts and in regard to performing graceful reset
when needed (instead of immediate reset).
- Add support for assert interrupt from the TPC engine.
- Get the reset type that is necessary to perform per event from the
auto-generated irq_map array.
- Print the specific reason why a device is still in use when notifying to
the user about it (after the user closed the device's FD).
- Move to threaded IRQ when handling interrupts of workload completions.
- Firmware related fixes:
- Fix RAZWI event handler to match newest f/w version.
- Read error cause register in dma core events because the f/w doesn't
do that.
- Increase maximum time to wait for completion of Gaudi2 reset due to f/w
bug.
- Align to the latest firmware specs.
- Enforce the release order of the compute device and dma-buf.
i.e increment the device file refcount for any dma-buf that was exported
for that device. This will make sure the compute device release function
won't be called until the user closes all the FDs of the relevant
dma-bufs. Without this change, closing the device's FD before/without
closing the dma-buf's FD would always lead to hard-reset of the device.
- Fix a link in the drm documentation to correctly point to the accel section.
- Compilation warnings cleanups
- Misc bug fixes and code cleanups

Implement fbdev emulation that is optimized for drivers that use
DMA helpers. The buffers may no tbe moveable, may not require damage
handling and have to be located in system memory. This allows fbdev
emulation to operate directly on the buffer and mmap it to userspace.
Besides those constraints, the emulation works like in the generic
code. As an internal DRM client provides, it receives hotplug, restore
and unregister events. The DRM client is independent from the fbdev
probing, which runs on the first successful hotplug event.
The emulation is part of the DMA helper module and not build unless
DMA helpers and fbdev emulation has been configured.
Tested with vc4.

Remove the bogus csync check and replace it with something that:
- triggers for all forms of csync, not just the basic analog variant
- actually populates the mode csync flags so that drivers can
decide what to do with the mode
Originally the code tried to outright reject csync, but that
apparently broke some bogus LCD monitor that claimed to have
a detailed mode that uses analog csync, despite also claiming
the monitor only support separate sync:
https://bugzilla.redhat.com/show_bug.cgi?id=540024
Potentially that monitor should just be quirked or something.
Anyways, what we are dealing with now is some kind of funny i915
JSL machine with eDP where the panel claims to support a sensible
60Hz separate sync mode, and a 50Hz mode with bipolar analog
csync. The 50Hz mode does not work so we want to not use it.
Easiest way is to just correctly flag it as csync and the driver
will reject it.
TODO: or should we just reject any form of csync (or at least
the analog variants) for digital display interfaces?

Consider this scenario:
1. APP1 continuously creates lots of small GEMs
2. APP2 triggers `drop_caches`
3. Shrinker starts to evict APP1 GEMs, while APP1 produces new purgeable
GEMs
4. msm_gem_shrinker_scan() returns non-zero number of freed pages
and causes shrinker to try shrink more
5. msm_gem_shrinker_scan() returns non-zero number of freed pages again,
goto 4
6. The APP2 is blocked in `drop_caches` until APP1 stops producing
purgeable GEMs
To prevent this blocking scenario, check number of remaining pages
that GPU shrinker couldn't release due to a GEM locking contention
or shrinking rejection. If there are no remaining pages left to shrink,
then there is no need to free up more pages and shrinker may break out
from the loop.
This problem was found during shrinker/madvise IOCTL testing of
virtio-gpu driver. The MSM driver is affected in the same way.

The DisplayID structure version and primary use case are stored in the
DisplayID Base Section. We should be checking them in a number of places
when parsing the DisplayID blocks. Currently, we completely ignore the
primary use case, and just look at the block tags without cross-checking
against structure version.
Store the version and primary use case in the DisplayID iterator, and
provide accessors to them. In general, the information is needed when
iterating the blocks, and this is a convenient place to both store and
retrieve the information during parsing.
Promote using accessors rather than users poking at the iterator
directly.

Pull driver core updates from Greg KH:
"Here is the large set of driver core changes for 6.3-rc1.
There's a lot of changes this development cycle, most of the work
falls into two different categories:
- fw_devlink fixes and updates. This has gone through numerous review
cycles and lots of review and testing by lots of different devices.
Hopefully all should be good now, and Saravana will be keeping a
watch for any potential regression on odd embedded systems.
- driver core changes to work to make struct bus_type able to be
moved into read-only memory (i.e. const) The recent work with Rust
has pointed out a number of areas in the driver core where we are
passing around and working with structures that really do not have
to be dynamic at all, and they should be able to be read-only
making things safer overall. This is the contuation of that work
(started last release with kobject changes) in moving struct
bus_type to be constant. We didn't quite make it for this release,
but the remaining patches will be finished up for the release after
this one, but the groundwork has been laid for this effort.
Other than that we have in here:
- debugfs memory leak fixes in some subsystems
- error path cleanups and fixes for some never-able-to-be-hit
codepaths.
- cacheinfo rework and fixes
- Other tiny fixes, full details are in the shortlog
All of these have been in linux-next for a while with no reported
problems"
[ Geert Uytterhoeven points out that that last sentence isn't true, and
that there's a pending report that has a fix that is queued up - Linus ]

In order to add a syncobj's fence as a dependency to a job, it is
necessary to call drm_syncobj_find_fence() to find the fence and then
add the dependency with drm_sched_job_add_dependency(). So, wrap these
steps in one single function, drm_sched_job_add_syncobj_dependency().

the inverse of the atomic_disable plane helper. Useful for hardware

Atm, drm_dp_remove_payload() uses the same payload state to both get the
vc_start_slot required for the payload removal DPCD message and to
deduct time_slots from vc_start_slot of all payloads after the one being
removed.
The above isn't always correct, as vc_start_slot must be the up-to-date
version contained in the new payload state, but time_slots must be the
one used when the payload was previously added, contained in the old
payload state. The new payload's time_slots can change vs. the old one
if the current atomic commit changes the corresponding mode.
This patch let's drivers pass the old and new payload states to
drm_dp_remove_payload(), but keeps these the same for now in all drivers
not to change the behavior. A follow-up i915 patch will pass in that
driver the correct old and new states to the function.

This time we've added support for reporting of GPU load via the common
fdinfo format, as already supported by multiple other drivers. Improved
diagnostic messages for MMU faults. And finally added experimental
support for driving the VeriSilicon NPU cores, which are very close
relatives to the GPU designs, so close in fact that they can run the
same compute instruction set, but with a big NN-fabric/matrix/tensor
execution array glued to the side.

Track the accumulated time that jobs from this entity were active
on the GPU. This allows drivers using the scheduler to trivially
implement the DRM fdinfo when the hardware doesn't provide more
specific information than signalling job completion anyways.

We reference dump buffers both by their handle as well as their
object. The problem is now that when anybody iterates over the DRM
framebuffers and exports the underlying GEM objects through DMA-buf
we run into a circular reference count situation.
The result is that the fbdev handling holds the GEM handle preventing
the DMA-buf in the GEM object to be released. This DMA-buf in turn
holds a reference to the driver module which on unload would release
the fbdev.
Break that loop by releasing the handle as soon as the DRM
framebuffer object is created. The DRM framebuffer and the DRM client
buffer structure still hold a reference to the underlying GEM object
preventing its destruction.

usual, and people have been asking where they are. Backmerge to get
things better in sync.
Conflicts:
- Tiny conflict in drm_fbdev_generic.c between variable rename and
missing error handling that got added.
- Conflict in drm_fb_helper.c between the added call to vgaswitcheroo
in drm_fb_helper_single_fb_probe and a refactor patch that extracted
lots of helpers and incidentally removed the dev local variable.
Readd it to make things compile.
