I think we should do this for common HDMI modes too.

Imo we still have a few lower-hanging fruit before we need to start doing clock fine-tuning in hdmi-land: Atm we don't really bother with supporting the 1001/1000 modified clocks in the CEA spec at all ... Once we have the support code for that, adding fine-tuned clocks for those modes starts to make sense, so that we really hit them spot-on. -Daniel -- Daniel Vetter Software Engineer, Intel Corporation +41 (0) 79 365 57 48 - http://blog.ffwll.ch -------------- next part -------------- An HTML attachment was scrubbed...
