habanalabs: define events to trace PCI LBW access
There are cases where it may be useful to dump the whole LBW configs.
Yet, doing so while spamming the kernel log will probably shade other
important messages since the LBW access is done in sheer volume.
To answer this we add trace events for those too.

habanalabs: fix dmabuf to export only required size
This patch fixes a bug that was found in the dmabuf flow.
Bug description as found on Gaudi2 device:
1. User allocates 4MB of device memory
- Note that although the allocation size was 4MB the HMMU allocated
a full page of 768MB to back the request.
- The user gets a memory handle that points to a single page (768MB)
- Mapping the handle, the user gets virtual address to the start of
the page.
2. User exports the buffer
3. User registers the exported buffer in the importer. This flow has
a callback to the exporter which in turn converts the phys_page_pack
to an SG list for the importer. This SG list is of single entry of
size 768MB. However, the size that was passed to the importer was
only 4MB.
The solution for this is to make sure the importer gets exposure only
to the exported size.
This will be done by fixing the SG created by the exporter to be of
the total size of the actual exported memory requested by the user.

Sometimes we need the binning info at a very early state of the
driver initialization. Therefore, support was added in preboot to
provide the binning info as part of the f/w descriptor and the driver
can now use that.

drm/edid: add separate drm_edid_connector_add_modes()
The original goal with drm_edid_connector_update() was to have a single
call for updating the connector and adding probed modes, in this order,
but that turned out to be problematic. Drivers that need to update the
connector in the .detect() callback would end up updating the probed
modes as well. Turns out the callback may be called so many times that
the probed mode list fills up without bounds, and this is amplified by
add_alternate_cea_modes() duplicating the CEA modes on every call,
actually running out of memory on some machines.
Kudos to Imre Deak <imre.deak@intel.com> for explaining this to me.
Go back to having separate drm_edid_connector_update() and
drm_edid_connector_add_modes() calls. The former may be called from
.detect(), .force(), or .get_modes(), but the latter only from
.get_modes().
Unlike drm_add_edid_modes(), have drm_edid_connector_add_modes() update
the probed modes from the EDID property instead of the passed in
EDID. This is mainly to enforce two things:
1) drm_edid_connector_update() must be called before
drm_edid_connector_add_modes().
Display info and quirks are needed for parsing the modes, and we
don't want to call update_display_info() again to ensure the info is
available, like drm_add_edid_modes() does.
2) The same EDID is used for both updating the connector and adding the
probed modes.
Fortunately, the change is easy, because no driver has actually adopted
drm_edid_connector_update(). Not even i915, and that's mainly because of
the problem described above.

drm/edid: split HDMI VSDB info and mode parsing
Separate the parsing of display info and modes from the HDMI VSDB. This
is prerequisite work for overall better separation of the two parsing
steps.
The info parsing is about figuring out whether the sink supports HDMI
infoframes. Since they were added in HDMI 1.4, assume the sink supports
HDMI infoframes if it has the HDMI_Video_present bit set (introduced in
HDMI 1.4). For details, see commit
f1781e9bb2dd ("drm/edid: Allow HDMI
infoframe without VIC or S3D").
The logic is not exactly the same, but since it was somewhat heuristic
to begin with, assume this is close enough.

- Simplify to only check HDMI_Video_present bit (Ville)
- Drop cea_db_raw_size() helper (Ville)

drm: exynos: dsi: Fix MIPI_DSI*_NO_* mode flags
HFP/HBP/HSA/EOT_PACKET modes in Exynos DSI host specifies
0 = Enable and 1 = Disable.
The logic for checking these mode flags was correct before
the MIPI_DSI*_NO_* mode flag conversion.
This patch is trying to fix this MIPI_DSI*_NO_* mode flags handling
Exynos DSI host and update the mode_flags in relevant panel drivers.

accel/ivpu: Add command buffer submission logic
Each of the user contexts has two command queues, one for compute engine
and one for the copy engine. Command queues are allocated and registered
in the device when the first job (command buffer) is submitted from
the user space to the VPU device. The userspace provides a list of
GEM buffer object handles to submit to the VPU, the driver resolves
buffer handles, pins physical memory if needed, increments ref count
for each buffer and stores pointers to buffer objects in
the ivpu_job objects that track jobs submitted to the device.
The VPU signals job completion with an asynchronous message that
contains the job id passed to firmware when the job was submitted.
Currently, the driver supports simple scheduling logic
where jobs submitted from user space are immediately pushed
to the VPU device command queues. In the future, it will be
extended to use hardware base scheduling and/or drm_sched.
