8 * DRM core CRTC related functions
61 * A CRTC represents the overall display pipeline. It receives pixel data from
63 * to the CRTC, specifying display timings. On the output side the data is fed
67 * To create a CRTC, a KMS drivers allocates and zeroes an instances of
71 * The CRTC is also the entry point for legacy modeset operations, see
80 * drm_crtc_from_index - find the registered CRTC at an index
82 * @idx: index of registered CRTC to find for
84 * Given a CRTC index, return the registered CRTC from DRM device's
