We need a virtual tool that would emulate a physical
connector unplug to usermode, while connector is
still physically plugged in.
[how]
Added a new option to debugfs entry "trigger_hotplug".
It emulates hotplug irq handling scenario by clearing
DC and DM connector states.
It can be triggered with the following command:
echo 0 > /sys/kernel/debug/dri/0/DP-X/trigger_hotplug

For debug purposes we want not to enable DSC on certain connectors
even if algorithm deesires to do so, instead it should enable DSC
on other capable connectors or fail the atomic check.
[how]
Adding the third option to connector's debugfs entry dsc_clock_en.
Accepted inputs:
0x0 - connector is using default DSC enablement policy
0x1 - force enable DSC on the connector, if it supports DSC
0x2 - force disable DSC on the connector, if DSC is supported
Ex. # echo 0x2 > /sys/kernel/debug/dri/0/DP-1/dsc_clock_en

[How]
Implement a basic caching algorithm that will cache DCValidator with a
matching topology. When a match is found, the DCValidator can be
reused. If there is no match, a new one will be created and inserted
into the cache if there is space or an unreference entry can be evicted.

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

[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.

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:
