If all relevant displays have the same pixel clock, this allows the driver to: - use fewer PPLLs which saves power - support more than two non-DP displays on DCE4+ The current drm modesetting infrastructure doesn't really provide a good framework for validating combinations that work or won't work, so it's possible you could go from a working configuration to a non-working one by changing the mode a one of the displays. However, there this is better than what was there before. Signed-off-by: Alex Deucher --- Reading git-diff-tree failed
