ba578afd5a drm/amd/display: disable stream if pixel clock changed with link active
[Why]
Vbios uses preferred timing to turn on edp but OS could use other
timing. If change pixel clock when link active, there is unexpected
garbage on monitor.

[How]
Once pixel clock changed, the driver needs to disable stream.

99d1437aa0 drm/amd/display: Check for flip pending before locking pipes.
[Why]
When running a game/benchmark with v-sync disabled, disabling a plane
(which is v-sync) can cause an underflow. This is due to flips that are
pending before pipe locking being applied after locks are released and
pipes have been re-arranged or disconnected. This can potentially apply
a flip on the incorrect pipe.

[How]
Check that any pending flips are cleared before locking any pipes to
ensure flips are applied on the correct pipes.

There are situations where we go from 2 pipe to 1 pipe in MPO, but this
isn't a pipe split being lost -- it's a plane disappearing in (i.e. video overlay
goes away) so we lose one pipe. In these situations we don't want to
disable the pipe in a separate operation from the rest of the pipe
programming sequence. We only want to disable a pipe in a
separate operation when we're actually disabling pipe split.

Make sure the pipe being lost has the same stream AND plane
as the old top pipe to ensure.

172c9b7781 drm/amd/display: Power eDP panel back ON before link training retry
[why]
When link training failures occur for eDP, dp_disable_link_phy
is called which powers OFF eDP panel. After link training retry
delay, the next retry begins by calling dp_enable_link_phy
which does not issue a correspnding eDP panel power ON, leaving
panel powered OFF which leads to display OFF/dark.

[how]
Power ON eDP before next link training retry.

05e3d830fa drm/amd/display: Only use offset for first ODM pipe
[WHY]
Only the first pipe in ODM combine group should have nonzero recout
offset. All other pipes should have recout offset 0;
otherwise there will be gaps in the image.

[HOW]
Set recout.x to 0 if the pipe is not the leftmost ODM pipe.

When computing viewports, calculate the horizontal offset of a pipe's src
based on the current pipe's position in the ODM group, plus whatever offset the
leftmost ODM pipe has; otherwise there will be discontinuity in the image.

Since ODM combine can only combine pipes horizontally, nothing needs to
be done for recout.y.

3fb068c3ec drm/amd/display: always use 100us for cr aux rd interval
[why]
The cr training aux rd interval is
modified without following specs requirements.
According to the commit message the change was not intended to modify the value.
Therefore it looks like it is caused by a typo in the change.

4b4f21ff7f drm/amd/display: Check clock table return
During the load processes for Renoir, our display code needs to retrieve
the SMU clock and voltage table, however, this operation can fail which
means that we have to check this scenario. Currently, we are not
handling this case properly and as a result, we have seen the following
dmesg log during the boot:

RIP: 0010:rn_clk_mgr_construct+0x129/0x3d0 [amdgpu]
...
Call Trace:
 dc_clk_mgr_create+0x16a/0x1b0 [amdgpu]
 dc_create+0x231/0x760 [amdgpu]

This commit fixes this issue by checking the return status retrieved
from the clock table before try to populate any bandwidth.
