Merge branch 'drm-vbl-timestamp' of git://gitorious.org/vsyrjala/linux into drm-next
Here's the vblank timestamp pull request you wanted. I addressed the few bugs that Mario pointed out and added the r-bs. As it has been a while since I made the changes, I gave it a quick spin on a few different i915 machines. Fortunately everything still seems to be fine. * 'drm-vbl-timestamp' of git://gitorious.org/vsyrjala/linux: drm/i915: Add a kludge for DSL incrementing too late and ISR not working drm/radeon: Move the early vblank IRQ fixup to radeon_get_crtc_scanoutpos() drm: Pass 'flags' from the caller to .get_scanout_position() drm: Fix vblank timestamping constants for interlaced modes drm/i915: Fix scanoutpos calculations for interlaced modes drm: Change {pixel,line,frame}dur_ns from s64 to int drm: Use crtc_clock in drm_calc_timestamping_constants() drm/radeon: Populate crtc_clock in radeon_atom_get_tv_timings() drm: Simplify the math in drm_calc_timestamping_constants() drm: Improve drm_calc_timestamping_constants() documentation drm/i915: Call drm_calc_timestamping_constants() earlier drm/i915: Kill hwmode save/restore drm: Pass the display mode to drm_calc_vbltimestamp_from_scanoutpos() drm: Pass the display mode to drm_calc_timestamping_constants()
