  50 * Description:
  51 *  Structure holding timing and resolution information of a standard.
  52 * Used by vpbe_device to set required non-standard timing in the
  53 * venc when lcd controller output is connected to a external encoder.
  54 * A table of timings is maintained in vpbe device to set this in
  55 * venc when external encoder is connected to lcd controller output.
  56 * Encoder may provide a g_dv_timings() API to override these values
  57 * as needed.
  58 *
  59 *  Notes
  60 *  ------
  61 *  if_type should be used only by encoder manager and encoder.
  62 *  flags usage
  63 *     b0 (LSB) - hsync polarity, 0 - negative, 1 - positive
  64 *     b1       - vsync polarity, 0 - negative, 1 - positive
  65 *     b2       - field id polarity, 0 - negative, 1  - positive
