Daniel Vetter 135c81b8c3 drm/i915: clean up crtc timings computation ... In the old days of the crtc helpers we've only had the encoder and crtc ->mode_fixup callbacks. So when the lvds connector wanted to adjust the crtc timings it had to set a driver-private mode flag to tell the crtc mode fixup code to not overwrite them with the generic ones. When converting things to the new infrastructure I've kept the entire logic and only moved the flag to pipe_config->timings_set. But this logic is pretty tricky and already caused regressions: commit 21d8a4756a Author: Daniel Vetter <daniel.vetter@ffwll.ch> Date: Fri Jul 12 08:07:30 2013 +0200 drm/i915: fix pfit regression for non-autoscaled resolutions So take advantage of the flexibility our own modeset infrastructure affords us and prefill default crtc timings. This allows us to rip out ->timings_set. Note that we overwrite things again when retrying the pipe config computation due to bandwidth constraints to avoid bogus crtc timings if the encoder only does relative adjustments (which is how the pfit code works). Only a theoretical concern though since platforms where we retry (pch-split platforms) do not need adjustements (since only the old gmch pfit needs that). But let's better be safe than sorry. Since we now initialize the crtc timings before calling the encoder->compute_config functions the crtc initialization in the gmch pfit code is now redudant and so can be removed.
