commit 1e66a17ce546eabad753178bbd4175cb52bafca8 upstream.

This reverts commit 072030b1783056b5de8b0fac5303a5e9dbc6cfde.
This is no longer necessary when using newer DMUB F/W.

<content type='text'>
commit 072030b1783056b5de8b0fac5303a5e9dbc6cfde upstream.

A number of users have reported that there are random hangs occurring
caused by PSR-SU specifically on panels that contain the parade 0803
TCON.  Users have been able to work around the issue by disabling PSR
entirely.

To avoid these hangs, disable PSR-SU when this TCON is found.

[ Upstream commit 0b5dfe12755f87ec014bb4cc1930485026167430 ]

[Why &amp; How]

timing.dsc_cfg.num_slices_v can be zero and it is necessary to check
before using it.

This fixes the error "divide error: 0000 [#1] PREEMPT SMP NOPTI".

<content type='text'>
[ Upstream commit 13b90cf900ab69dd5cab3cc5035bc7614037e64e ]

Currently, there are issues with enabling PSR-SU + DSC. This stems from
the fact that DSC imposes a slice height on transmitted video data and
we are not conforming to that slice height in PSR-SU regions. So, pass
slice_height into su_y_granularity to feed the DSC slice height into
PSR-SU code.

<title>drm/amd/display: fix transfer function passed to build_coefficients()</title>

<content type='text'>
The default argument should be enum TRANSFER_FUNCTION_SRGB rather than
the current boolean value which improperly maps to
TRANSFER_FUNCTION_BT709.

Commit 9b3d76527f6e ("drm/amd/display: Revert adding degamma coefficients")
looks to have improperly reverted
commit d02097095916 ("drm/amd/display: Add regamma/degamma coefficients and set sRGB when TF is BT709")
replacing the enum value with a boolean value.

<title>drm/amd/display: Limit user regamma to a valid value</title>

<id>urn:sha1:61e4de65b99c616d5e074a9e2a4a1a9f821a964b</id>
<content type='text'>
[Why]
For HDR mode, we get total 512 tf_point and after switching to SDR mode
we actually get 400 tf_point and the rest of points(401~512) still use
dirty value from HDR mode. We should limit the rest of the points to max
value.

[How]
Limit the value when coordinates_x.x &gt; 1, just like what we do in
translate_from_linear_space for other re-gamma build paths.

Some specific sink is not able to support PSRSU when DSC is turned on.
For this case, fall-back to use PSR1.

[WHY]
The display driver on some OSes need to track it in order to
perform memory clock switching decisions.

[HOW]
Propagate the vrr active state to dirty bit so that on mode set it
disables dynamic memory clock switching.
