- * @get_vblank_timestamp:

- * Specifically, the timestamp in @vblank_time should correspond as
- * closely as possible to the time when the first video scanline of
- * the video frame after the end of VBLANK will start scanning out,
- * the time immediately after end of the VBLANK interval. If the

- * Paramters:
- *
- * dev:
- * dev DRM device handle.
- * pipe:
- * crtc for which timestamp should be returned.
- * max_error:
- * Maximum allowable timestamp error in nanoseconds.
