If anyone has any objections, please let me know. ------------------ From: Timur Kristóf [ Upstream commit 0e190a0446ec517666dab4691b296a9b758e590f ] Scaling doesn't work on DCE6 at the moment, the current register programming produces incorrect output when using fractional scaling (between 100-200%) on resolutions higher than 1080p. Disable it until we figure out how to program it properly.
