  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
