* 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
