+ * Description:
+ *  Structure holding timing and resolution information of a standard.
+ * Used by vpbe_device to set required non-standard timing in the
+ * venc when lcd controller output is connected to a external encoder.
+ * A table of timings is maintained in vpbe device to set this in
+ * venc when external encoder is connected to lcd controller output.
+ * Encoder may provide a g_dv_timings() API to override these values
+ * as needed.
+ *
+ *  Notes
+ *  ------
+ *  if_type should be used only by encoder manager and encoder.
