 * struct vpbe_enc_mode_info
 * @name: ptr to name string of the standard, "NTSC", "PAL" etc
 * @std: standard or non-standard mode. 1 - standard, 0 - nonstandard
 * @interlaced: 1 - interlaced, 0 - non interlaced/progressive
 * @xres: x or horizontal resolution of the display
 * @yres: y or vertical resolution of the display
 * @fps: frame per second
 * @left_margin: left margin of the display
 * @right_margin: right margin of the display
 * @upper_margin: upper margin of the display
 * @lower_margin: lower margin of the display
 * @hsync_len: h-sync length
 * @vsync_len: v-sync length
 * @flags: bit field: bit usage is documented below
 *
 * 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.
 *  flags usage
 *     b0 (LSB) - hsync polarity, 0 - negative, 1 - positive
 *     b1       - vsync polarity, 0 - negative, 1 - positive
 *     b2       - field id polarity, 0 - negative, 1  - positive
