But a bug report and a closer look at the wrpll table showed that we've supported port clocks up to 300MHz. With the new code to dynamically compute wrpll limits we should have no issues going up to the full 340 MHz range of hdmi 1.4, so let's just use that to fix this regression. That'll allow 4k over hdmi for free! v2: Drop the random hunk that somehow slipped in. v3: Cantiga has the original HDMI dotclock limit of 165MHz. And also patch up the mode filtering. To do so extract the dotclock limits into a little helper function. v4: Use 300MHz (from Bspec) instead of 340MHz (upper limit for hdmi 1.3), apparently hw is not required to be able to drive the highest dotclocks.
