- * Driver callback for fetching a raw hardware vblank counter
- * for @crtc. If a device doesn't have a hardware counter, the
- * driver can simply return the value of drm_vblank_count and
- * make the enable_vblank() and disable_vblank() hooks into no-ops,
- * leaving interrupts enabled at all times.
