ec0ca697dd drm/amd/display: Validate DSC caps on MST endpoints
During MST mode enumeration, if a new dc_sink is created,
populate it with dsc caps as appropriate.

Use drm_dp_mst_dsc_aux_for_port to get the raw caps,
then parse them onto dc_sink with dc_dsc_parse_dsc_dpcd.

b6adc57cff drm/amd/display: Initialize DSC PPS variables to 0
For DSC MST, sometimes monitors would break out
in full-screen static. The issue traced back to the
PPS generation code, where these variables were being used
uninitialized and were picking up garbage.

memset to 0 to avoid this

dc48529fb1 drm/dp_mst: Add PBN calculation for DSC modes
With DSC, bpp can be fractional in multiples of 1/16.

Change drm_dp_calc_pbn_mode to reflect this, adding a new
parameter bool dsc. When this parameter is true, treat the
bpp parameter as having units not of bits per pixel, but
1/16 of a bit per pixel

v2: Don't add separate function for this
v3: In the equation divide bpp by 16 as it is expected
not to leave any remainder
v4: Added DSC test parameters for selftest

ea117312ea drm/amd/display: Reduce HDMI pixel encoding if max clock is exceeded
For high-res (8K) or HFR (4K120) displays, using uncompressed pixel
formats like YCbCr444 would exceed the bandwidth of HDMI 2.0, so the
"interesting" modes would be disabled, leaving only low-res or low
framerate modes.

This change lowers the pixel encoding to 4:2:2 or 4:2:0 if the max TMDS
clock is exceeded. Verified that 8K30 and 4K120 are now available and
working with a Samsung Q900R over an HDMI 2.0b link from a Radeon 5700.

d12babaf15 drm/amd/display: add event type check before restart the authentication
[Why]
Some combined docks will always trigger CP_IRQ but there's nothing the driver
needs to take care of, but the CP_IRQ breaks the original hdcp state and
triggers the driver to restart the authentication.

[How]
Add the event type check before restart the authentication or resend the stream
management

daa9692db9 drm/amd/display: Add delay after h' watchdog timeout event
[WHY]
Some monitors trigger HDCP2.x timeout after reinitializing (e.g. toggling HDR)
by taking longer than expected to return h' (h prime)
Previously the 200ms watchdog timer retry count would hit
MAX_NUM_OF_ATTEMPTS (4), causing fallback to HDCP1.x

[HOW]
Adding a 1s delay after an h' watchdog timeout provides enough time
for affected monitors to return h' in time without hitting MAX_NUM_OF_ATTEMPTS

6426745427 drm/amd/display: fix missing cursor on some rotated SLS displays
[Why]
Cursor disappears for some SLS displays that are rotated 180
and 270 degrees.  This occurs when there is no pipe split being
done ( ex. 3 or more displays ).  The cursor calculations assume
pipe splitting is done so when it calculates the new cursor
position in hwss.set_cursor_position(), it is out-of-bounds so
it disables the cursor in hubp.set_cursor_position().

[How]
In non pipe split cases, calculate cursor using viewport size
( width or height ) instead of viewport size * 2 ( the two
because pipe splitting divides the rectangle into two ).

5479034576 drm/amd/display: Lower DPP DTO only when safe
[Why]
A corner case currently exists where DPP DTO is lowered before
pipes are updated to a higher viewport. This causes underflow
as the DPPCLK is too low for the current viewport.

[How]
Only lower DPP DTO when it is safe to lower, or if
the newer clocks are higher than the current ones.

89d07b662f drm/amd/display: fix 270 degree rotation for mixed-SLS mode
[Why]
When we rotate 270 in mixed SLS mode, the recouts occupy the
right side of the display.  So all the recout_skip_v values
are relative to the left side of the display.  This causes
adjust_vp_and_init_for_seamless_clip() to incorrectly increase
the data->viewport.height for that recout.  The rotation looks
like the bottom half is duplicated twice.

[How]
recout.x values are being adjusted based on
stream->timing.h_border_left.  Instead of using h_border_left,
use dst.x to represent the border.  Shift dst.x by the amount of
stream->timing.h_border_left and set
stream->timing.h_border_left to 0.  Do all the calculations
and then revert stream->timing.h_border_left and
stream->dst.x back to their original values.
When calculating pipe_ctx->plane_res.scl_data.h_active,
make sure to use the original stream->timing.h_border_left
value.

ec5b356c58 drm/amd/display: Map ODM memory correctly when doing ODM combine
[why]
Up to 4 ODM memory pieces are required per ODM combine and cannot
overlap, i.e. each ODM "session" has to use its own memory pieces.
The ODM-memory mapping is currently broken for generic case.

The maximum number of memory pieces is ASIC-dependent, but it's always
big enough to satisfy maximum number of ODM combines. Memory pieces
are mapped as a bit-map, i.e. one memory piece corresponds to one bit.
The OPTC doing ODM needs to select memory pieces by setting the
corresponding bits, making sure there's no overlap with other OPTC
instances that might be doing ODM.

The current mapping works only for OPTC instance indexes smaller than
3. For instance indexes 3 and up it practically maps no ODM memory,
causing black, gray or white screen in display configs that include
ODM on OPTC instance 3 or up.

[how]
Statically map two unique ODM memory pieces for each OPTC instance
and piece them together when programming ODM combine mode.
