Yes, the log is from drm-tip. 
The dfference is that intel_psr_enable_locked is not called in drm-tip at the
boot time baut called on resume, but on 5.4-rc7 it is called at the boot time.
So with drm-tip the system detects that sink is psr1 compatible but somehow
skips the activation step. In 5.4-rc7 main tree it activetes psr on initial
boot. I tried to find out where it shoud be triggered but my knowledge is not
enough for it. I've just tried to comment out all the points where the psr is
deactivated due to errors and it is still not enabled after boot until first
suspend-resume. So it is not activated and then disabled, it is just not
activated.
