<title>drm/amd/display: don't ignore alpha property on pre-multiplied mode</title>

<id>urn:sha1:f616ecec0faef8f5df75fe9917c84a68156603fe</id>
<content type='text'>
commit e4f1541caf60fcbe5a59e9d25805c0b5865e546a upstream.

"Pre-multiplied" is the default pixel blend mode for KMS/DRM, as
documented in supported_modes of drm_plane_create_blend_mode_property():
https://cgit.freedesktop.org/drm/drm-misc/tree/drivers/gpu/drm/drm_blend.c

In this mode, both 'pixel alpha' and 'plane alpha' participate in the
calculation, as described by the pixel blend mode formula in KMS/DRM
documentation:

out.rgb = plane_alpha * fg.rgb +
          (1 - (plane_alpha * fg.alpha)) * bg.rgb

Considering the blend config mechanisms we have in the driver so far,
the alpha mode that better fits this blend mode is the
_PER_PIXEL_ALPHA_COMBINED_GLOBAL_GAIN, where the value for global_gain
is the plane alpha (global_alpha).

With this change, alpha property stops to be ignored. It also addresses
Bug: https://gitlab.freedesktop.org/drm/amd/-/issues/1734

v2:
 * keep the 8-bit value for global_alpha_value (Nicholas)
 * correct the logical ordering for combined global gain (Nicholas)
 * apply to dcn10 too (Nicholas)

[ Upstream commit 5ceaebcda9061c04f439c93961f0819878365c0f ]

[WHY]
It seems like after a series of plug/unplugs we end up in a situation
where tiled display doesnt support Audio.

[HOW]
The issue seems to be related to when we check streams changed after an
HPD, we should be checking the audio_struct as well to see if any of its
values changed.

[ Upstream commit 554594567b1fa3da74f88ec7b2dc83d000c58e98 ]

The variable dc-&gt;clk_mgr is checked in:
  if (dc-&gt;clk_mgr &amp;&amp; dc-&gt;clk_mgr-&gt;funcs-&gt;get_clock)

This indicates dc-&gt;clk_mgr can be NULL.
However, it is dereferenced in:
    if (!dc-&gt;clk_mgr-&gt;funcs-&gt;get_clock)

To fix this null-pointer dereference, check dc-&gt;clk_mgr and the function
pointer dc-&gt;clk_mgr-&gt;funcs-&gt;get_clock earlier, and return if one of them
is NULL.

[ Upstream commit 23e55639b87fb16a9f0f66032ecb57060df6c46c ]

[why]
The units of the time_per_pixel variable were incorrect, this had to be
changed for the code to properly function.

[how]
The change was very straightforward, only required one line of code to
be changed where the calculation was done.

In DCN2x, HW doesn't automatically divide MASTER_UPDATE_LOCK_DB_X
by the number of pipes ODM Combined.

Set MASTER_UPDATE_LOCK_DB_X to the value that is adjusted by the
