- Subject: [PATCH 291/381] drm/vc4: Fix setting of vertical timings in the CRTC.
- It looks like when I went to add the interlaced bits, I just took the
- existing PV_VERT* block and indented it, instead of copy and pasting
- it first. Without this, changing resolution never worked.
- Signed-off-by: Eric Anholt <eric@anholt.net>
- (cherry picked from commit a7c5047d1ce178dd2b1fa577fc8909ad663d56d5)
