drm/amd/display: Parse scanline registers
They could differ between ASIC generations
Change-Id: Ia352ae206273fe3a025579554cae4e3711a26fcc
on agd5f drm staging 4.9/11 there is a regression with full screen video.
mpv --vo=vaapi/vdpau/opengl all the same, dropping frames, or playing slowmo with --framedrop=no
Windowed playback is OK, testing with 60fps vid on 60Hz DVI-D display.
Forcing clocks high does not help.

Thanks, Andy. Please try attached patch. The regression change you mentioned contains some bad code (that I wrote -_-).

Thanks for testing. It should land in amd-staging-4.9 in a week or so.
Closed by Alex, but AFAICT the fix is only in amd-staging-4.11. 4.9 doesn't seem to have been touched for 4 weeks (unless cgit is wrong).

--- Comment #5 from Alex Deucher alexdeucher@gmail.com --- We've moved amd-staging to 4.11 and are not updating the 4.9 branch any more.
