  31 * struct vpbe_enc_mode_info
  32 * @name: ptr to name string of the standard, "NTSC", "PAL" etc
  33 * @std: standard or non-standard mode. 1 - standard, 0 - nonstandard
  34 * @interlaced: 1 - interlaced, 0 - non interlaced/progressive
  35 * @xres: x or horizontal resolution of the display
  36 * @yres: y or vertical resolution of the display
  37 * @fps: frame per second
  38 * @left_margin: left margin of the display
  39 * @right_margin: right margin of the display
  40 * @upper_margin: upper margin of the display

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