     38 * Description:
     39 *  Structure holding timing and resolution information of a standard.
     40 * Used by vpbe_device to set required non-standard timing in the
     41 * venc when lcd controller output is connected to a external encoder.
     42 * A table of timings is maintained in vpbe device to set this in
     43 * venc when external encoder is connected to lcd controller output.
     44 * Encoder may provide a g_dv_timings() API to override these values
     45 * as needed.
     46 *
     47 *  Notes
     48 *  ------
     49 *  if_type should be used only by encoder manager and encoder.
     50 *  flags usage
     51 *     b0 (LSB) - hsync polarity, 0 - negative, 1 - positive
     52 *     b1       - vsync polarity, 0 - negative, 1 - positive
     53 *     b2       - field id polarity, 0 - negative, 1  - positive
