With VRR the earliest the registers can get latched are at flipline decision boundary, calculate that as vrr_vmin_vblank_start() and the latest the regsiters can get latched are vmax decision boundary calculate that as vrr_vmax_vblank_start() v2: * Remove TODO and adjust extra scanline const (Manasi) Signed-off-by: Manasi Navare <manasi.d.navare@intel.com> Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Reviewed-by: Manasi Navare <manasi.d.navare@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20210122232647.22688-15-manasi.d.navare@intel.com
