drm: Implement timings adjustments for frame packing
When using the frame packing and a single big framebuffer, some hardware requires that we do everything like if we were scanning out the big buffer itself. Let's instrument drm_mode_set_crtcinfo() to be able to do this adjustement if the driver is asking for it. v2: Use crtc_vtotal and multiply the clock by 2 instead of reconstructing it (Ville Syrjälä) Suggested-by: Daniel Vetter <daniel.vetter@ffwll.ch> Reviewed-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Signed-off-by: Damien Lespiau <damien.lespiau@intel.com> Acked-by: Dave Airlie <airlied@gmail.com> Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch>
