+ * Overview
+ * --------
+ *
+ * The Xilinx CRTC layer is to enable the custom interface to CRTC drivers.
+ * The interface is used by Xilinx DRM driver where it needs CRTC
+ * functionality. CRTC drivers should attach the desired callbacks
+ * to struct xlnx_crtc and register the xlnx_crtc with corresponding
+ * drm_device. It's highly recommended CRTC drivers register all callbacks
+ * even though many of them are optional.
+ * The CRTC helper simply walks through the registered CRTC device,
+ * and calls the callbacks.
