Subject: drm/amd/display: Pass the new context into disable OTG WA
Git-commit: 8440f57532496d398a461887e56ca6f45089fbcf
Patch-mainline: v5.19-rc2
References: jsc#PED-1166 jsc#PED-1168 jsc#PED-1170 jsc#PED-1218 jsc#PED-1220 jsc#PED-1222 jsc#PED-1223 jsc#PED-1225
[Why]
When enabling an HPO stream for the first time after having previously
enabled a DIO stream there may be lingering DIO FIFO errors even though
the DIO is no longer enabled.
These can cause display clock change to hang if we don't apply the
OTG disable workaround since the ramping logic is tied to OTG on.
[How]
The workaround wasn't being applied in the sequence of:
1 DIO stream
0 streams
1 HPO stream
because current_state has no stream or planes in its context - and
it's only swapped after optimize has finished.
We should be using the incoming context instead to determine whether
this logic is needed or not.
