[Why]
The commit c76e483cd9 ("drm/amd/display: Don't restrict bpc to 8 bpc")
removes the historical 8bpc dependency and sets max_bpc to 16.
[How]
The comment that states "8bpc for non-edp" needs to be removed as well.

[Why and How]
Current implementation requires FPGA builds to take a different
code path from DCN32 to write to OTG_PIXEL_RATE_DIV. Now that
we have a workaround to write to OTG_PIXEL_RATE_DIV register without
blanking display on hotplug on DCN32, we can allow the code paths for
FPGA to be exactly the same allowing for more consistent
testing.

Refactor register_backlight_device():
1) Turn the connector-type + signal check into an early exit
condition to avoid the indentation level of the rest of the code
2) Add an array bounds check for the arrays indexed by dm->num_of_edps
3) register_backlight_device() always increases dm->num_of_edps if
amdgpu_dm_register_backlight_device() has assigned a backlight_dev to
the current dm->backlight_link[dm->num_of_edps] slot.
So on its next call dm->backlight_dev[dm->num_of_edps] always point to
the next empty slot and the "if (!dm->backlight_dev[dm->num_of_edps])"
check will thus always succeed and can be removed.
4) Add a bl_idx local variable to use as array index, rather then
using dm->num_of_edps to improve the code readability.

[Why]
For engines not supporting soft reset, i.e. VCN, there will be a failed
ib test before mode 1 reset during asic reset. The fences in this case
are never signaled and next time when we try to free the sa_bo, kernel
will hang.
[How]
During pre_asic_reset, driver will clear job fences and afterwards the
fences' refcount will be reduced to 1. For drm_sched_jobs it will be
released in job_free_cb, and for non-sched jobs like ib_test, it's meant
to be released in sa_bo_free but only when the fences are signaled. So
we have to force signal the non_sched bad job's fence during
pre_asic_reset or the clear is not complete.

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
