[Intel-gfx] [PATCH 08/15] drm/meson: Use drm_mode_get_hv_timing() to populate plane clip rectangle

[Ville Syrjala]

From: Ville Syrjälä <ville.syrjala at linux.intel.com>

Use drm_mode_get_hv_timing() to fill out the plane clip rectangle.

No functional changes as the code already uses crtc_state->mode
to populate the clip, which is also what drm_mode_get_hv_timing()
uses.

Once everyone agrees on this we can move the clip handling into
drm_atomic_helper_check_plane_state().
