[PATCH v3 07/22] drm/i915: Convert to CRTC VBLANK callbacks
Thomas Zimmermann

Mon Jan 20 08:22:59 UTC 2020
VBLANK callbacks in struct drm_driver are deprecated in favor of their
equivalents in struct drm_crtc_funcs. Convert i915 over.
The callback struct drm_driver.get_scanout_position() is deprecated
in favor of struct drm_crtc_helper_funcs.get_scanout_position().
i915 doesn't use CRTC helpers. Instead pass i915's implementation of
get_scanout_position() to DRM core's
drm_crtc_vblank_helper_get_vblank_timestamp_internal().
v3:
* rename dcrtc to _crtc
* use intel_ prefix for i915_crtc_get_vblank_timestamp()
* update for drm_crtc_vblank_helper_get_vblank_timestamp_internal()
v2:
* use DRM's implementation of get_vblank_timestamp()
* simplify function names
