9315e2399a drm/amd/display: Fix DP HBR2 Eye Diagram Pattern on Carrizo
[why] dp hbr2 eye diagram pattern for raven asic is not stabled.
workaround is to use tp4 pattern. But this should not be
applied to asic before raven.

[how] add new bool varilable in asic caps. for raven asic,
use the workaround. for carrizo, vega, do not use workaround.

5ae6fe5729 drm/amd/display: Use calculated disp_clk_khz value for dce110
[Why]

The calculated values for actual disp_clk_khz were ignored when
notifying pplib of the new display requirements. In order to honor DFS
bypass clocks from the hardware, the calculated value should be used.

[How]

The return value for set_dispclk is now assigned back into new_clocks
and correctly carried through into dccg->clks.phyclk_khz. When notifying
pplib of new display requirements dccg->clks.phyclk_khz is used
instead of dce.dispclk_khz. The value of dce.dispclk_khz was never
explicitly set to anything before.

A 15% higher display clock value than calculated is no longer requested
for dce110 since it now makes use of the calculated value.

Since dce112 makes use of dce110's set_bandwidth but not its
update_clocks it needs to have the value correctly carried through.

78e4405cec drm/amd/display: Implement custom degamma lut on dcn
[Why]
Custom degamma lut functions are a feature we would
like to support on compatible hardware

[How]
In atomic check, convert from array of drm_color_lut to
dc_transfer_func.  On hardware commit, allow for possibility
of custom degamma.  Both are based on the equivalent
regamma pipeline.

53a53f8687 drm/amd/display: Read back max backlight value at boot
[Why]
If there is no program explicitly setting the backlight
brightness (for example, during a minimal install of linux), the
hardware defaults to maximum brightness but the backlight_device
defaults to 0 value.  Thus, settings displays the wrong brightness
value.

[Why]
The DRM mode's HDMI picture aspect ratio field was never saved in

[How]
Only require EDID read for HDMI and DVI and exempt other types (DP,

01dc285d5c drm/amd/display: Report non-DP display as disconnected without EDID
[Why]
Some boards seem to have a problem where HPD is high on HDMI even though
no display is connected. We don't want to report these as connected. DP
spec still requires us to report DP displays as connected when HPD is
high but we can't read the EDID in order to go to fail-safe mode.

[How]
If connector_signal is not DP abort detection if we can't retrieve the
EDID.

9907704174 drm/amd/display: Prevent PSR from being enabled if initialization fails
[Why]
PSR_SET command is sent to the microcontroller in order to initialize
parameters needed for PSR feature, such as telling the microcontroller
which pipe is driving the PSR supported panel. When this command is
skipped or fails, the microcontroller may program the wrong thing if
driver tries to enable PSR.

If PSR_SET fails, do not set psr_enable flag to indicate the feature is
not yet initialized.

6d92b5c2d5 drm/amd/display: Refactor SDR cursor boosting in HDR mode
[Why]
Cursor boosting is done via CNVC_CUR register which is DPP, not HUBP
Previous commit was implementing it in HUBP functions,
and also breaking diags tests.

[How]
1. Undo original commit as well as Eric's diags test fix, almost completely
2. Move programming to DPP and call via new dc_stream function
3. Also removing cur_rom_en from dpp_cursor_attributes and programming
as part of normal cursor attributes as it depends on cursor color format

edf6ffe4f4 drm/amd/display: Read AUX channel even if only status byte is returned
[Why]
get_channel_status() can return 0 in returned_bytes, and report a
successful operation result. This is because it prunes the first status
byte out. This was preventing read_channel_reply() from being called
(due to the faulty condition), and consequently preventing the AUX
reply status from being set.

[How]
Fix the conditional so that it accounts for when get_channel_status()
returns 0 bytes read.

[Fixes]
Fixes possible edid read failures during S3 resume, where we are now
relying on DRM's DP AUX handling. This was an regression introduced by:

084b3765ec drm/amd/display: Return aux replies directly to DRM
Currently we still go through DC code that does error checking, retries,
etc. There's no need for that since DRM already does that for us. This
simplifies the code a bit and makes it easier to debug.

This also ensures we correctly tell DRM how many bytes have actually
been read, as we should. This allows DRM to correctly read the EDID on
the Chamelium DP port.

When a dce100 asic was suspended, the clocks were not set to 0.
Upon resume, the new clock was compared to the existing clock,
they were found to be the same, and so the clock was not set.

Add suffix ULL to constant 5 and cast variables target_pix_clk_khz and
feedback_divider to uint64_t in order to avoid multiple potential integer
overflows and give the compiler complete information about the proper
arithmetic to use.

Notice that such constant and variables are used in contexts that
expect expressions of type uint64_t (64 bits, unsigned). The current
casts to uint64_t effectively apply to each expression as a whole,
but they do not prevent them from being evaluated using 32-bit
arithmetic instead of 64-bit arithmetic.

Also, once the expressions are properly evaluated using 64-bit
arithmentic, there is no need for the parentheses that enclose
them.

The wrong enum type is used to initialize the result, leading to a

Initialization of result is unnecessary anyway, just drop the
