Add support for DSC 1.2 by providing the necessary hooks to program
the DPU DSC 1.2 encoder.
Changes in v3:
-- fixed kernel test rebot report that "__iomem *off" is declared but not
used at dpu_hw_dsc_config_1_2()
-- unrolling thresh loops
Changes in v4:
-- delete DPU_DSC_HW_REV_1_1
-- delete off and used real register name directly
Changes in v7:
-- replace offset with sblk->enc.base
-- replace ss with slice
Changes in v8:
-- fixed checkpatch warning
Changes in v9:
-- replaced __dsc_calc_ob_max_addr() with __dsc_calc_output_buf_max_addr()
-- replaced variable num_ss with num_softslice
-- remove inline from function declaration
changes in v10:
-- rewording text of changes in v9
-- replace DPU_DSC_NATIVE_422_EN with DPU_DSC_NATIVE_42x_EN
-- replace drm_dsc_calculate_flatness_det_thresh() with drm_dsc_flatness_det_thresh()

Currently, hdisplay is being divided by 3 for DSC. However, this
calculation only works for cases where BPP = 8.
Update hdisplay calculation to be bytes_per_line / 3, so that it
accounts for cases where BPP != 8.

The internal_hpd flag is set to true by dp_bridge_hpd_enable() and set to
false by dp_bridge_hpd_disable() to handle GPIO pinmuxed into DP controller
case. HDP related interrupts can not be enabled until internal_hpd is set
to true. At current implementation dp_display_config_hpd() will initialize
DP host controller first followed by enabling HDP related interrupts if
internal_hpd was true at that time. Enable HDP related interrupts depends on
internal_hpd status may leave system with DP driver host is in running state
but without HDP related interrupts being enabled. This will prevent external

The "vsync_hz" variable is unsigned int so it can't be less
than zero. The dpu_kms_get_clk_rate() function used to return a u64
but I previously changed it to return an unsigned long and zero on
error so it matches clk_get_rate().
Change the "vsync_hz" type to unsigned long as well and change the
error checking to check for zero instead of negatives. This change
does not affect runtime at all. It's just a clean up.

Add SM6350 support to the DPU1 driver to enable display output.
It's worth noting that one entry dpu_qos_lut_entry was trimmed off:
{.fl = 0, .lut = 0x0011223344556677 },
due to the lack of support for selecting between portrait and landscape
LUT settings (for danger and safe LUTs) and no full support for
qseed/non-qseed usescases (for QoS LUT).

Currently the driver passes the PINGPONG index to
dpu_hw_wb_ops::bind_pingpong_blk() callback and uses separate boolean
flag to tell whether WB should be bound or unbound. Simplify this by
passing PINGPONG_NONE in case of unbinding and drop the flag completely.

On DG2, capturing OA reports while running heavy render workloads
sometimes results in invalid OA reports where 64-byte chunks inside
reports have stale values. Under memory pressure, high OA sampling rates
(13.3 us) and heavy render workload, occasionally, the OA HW TAIL
pointer does not progress as fast as the sampling rate. When these
glitches occur, the TAIL pointer takes approx. 200us to progress. While
this is expected behavior from the HW perspective, invalid reports are
not expected.
In oa_buffer_check_unlocked(), when we execute the if condition, we are
updating the oa_buffer.tail to the aging tail and then setting pollin
based on this tail value, however, we do not have a chance to rewind and
validate the reports prior to setting pollin. The validation happens
in a subsequent call to oa_buffer_check_unlocked(). If a read occurs
before this validation, then we end up reading reports up until this
oa_buffer.tail value which includes invalid reports. Though found on
DG2, this affects all platforms.
The aging tail logic is no longer necessary since we are explicitly
checking for landed reports.
Start by dropping the aging tail logic.
v2:
- Drop extra blank line
- Add reason to drop aging logic (Ashutosh)
- Add bug links (Ashutosh)
- rename aged_tail to read_tail
- Squash patches 3 and 1
v3: (Ashutosh)
- Remove extra spaces
- Remove gtt_offset from the pollin calculation
- s/Bug:/Link/ in commit message (checkpatch)

To comply with the design that buffer objects shall have immutable
cache setting through out their life cycle, {set, get}_caching ioctl's
are no longer supported from MTL onward. With that change caching
policy can only be set at object creation time. The current code
applies a default (platform dependent) cache setting for all objects.
However this is not optimal for performance tuning. The patch extends
the existing gem_create uAPI to let user set PAT index for the object
at creation time.
The new extension is platform independent, so UMD's can switch to using
this extension for older platforms as well, while {set, get}_caching are
still supported on these legacy paltforms for compatibility reason.
However, since PAT index was not clearly defined for platforms prior to
GEN12 (TGL), so we are limiting this externsion to GEN12+ platforms
only. See ext_set_pat() in for the implementation details.
The documentation related to the PAT/MOCS tables is currently available
for Tiger Lake here:
https://www.intel.com/content/www/us/en/docs/graphics-for-linux/developer-reference/1-0/tiger-lake.html
The documentation for other platforms is currently being updated.

Add some missing error propagation in live_parallel_switch.
To avoid needlessly burdening the various backport processes, note I am
not marking it as a fix against any patches and not copying stable since
it is debug/selftests only code.

On MTL, for obvious reasons, HuC is only available on the media tile.
We already disable SW support for HuC on the root gt due to the
absence of VCS engines, but we also need to update the getparam to point
to the HuC struct in the media GT.
