[igt-dev] [PATCH i-g-t] tests/kms_dp_tiled_display: Request a mode on resolution that matches tile size

[Karthik B S]

Loop through the connector's modes for both the tiled connectors and 
find a mode that matches the tile h size and tile v size.
Request a modeset on this mode for both tiled connectors.
