/**
* drm_calc_vbltimestamp_from_scanoutpos - helper routine for kms
* drivers. Implements calculation of exact vblank timestamps from
* given drm_display_mode timings and current video scanout position
* of a crtc. This can be called from within get_vblank_timestamp()
* implementation of a kms driver to implement the actual timestamping.
*
* Should return timestamps conforming to the OML_sync_control OpenML
* extension specification. The timestamp corresponds to the end of
* the vblank interval, aka start of scanout of topmost-leftmost display
* pixel in the following video frame.
*
* Requires support for optional dev->driver->get_scanout_position()
* in kms driver, plus a bit of setup code to provide a drm_display_mode
* that corresponds to the true scanout timing.
*
* The current implementation only handles standard video modes. It
* returns as no operation if a doublescan or interlaced video mode is
* active. Higher level code is expected to handle this.
*
* @dev: DRM device.
* @crtc: Which crtc's vblank timestamp to retrieve.
* @max_error: Desired maximum allowable error in timestamps (nanosecs).
* On return contains true maximum error of timestamp.
* @vblank_time: Pointer to struct timeval which should receive the timestamp.
* @flags: Flags to pass to driver:
* 0 = Default.
* DRM_CALLED_FROM_VBLIRQ = If function is called from vbl irq handler.
* @refcrtc: drm_crtc* of crtc which defines scanout timing.
*
* Returns negative value on error, failure or if not supported in current
* video mode:
*
* -EINVAL - Invalid crtc.
* -EAGAIN - Temporary unavailable, e.g., called before initial modeset.
* -ENOTSUPP - Function not supported in current display mode.
* -EIO - Failed, e.g., due to failed scanout position query.
*
* Returns or'ed positive status flags on success:
*
* DRM_VBLANKTIME_SCANOUTPOS_METHOD - Signal this method used for timestamping.
* DRM_VBLANKTIME_INVBL - Timestamp taken while scanout was in vblank interval.
