0038  * Description:
0039  *  Structure holding timing and resolution information of a standard.
0040  * Used by vpbe_device to set required non-standard timing in the
0041  * venc when lcd controller output is connected to a external encoder.
0042  * A table of timings is maintained in vpbe device to set this in
0043  * venc when external encoder is connected to lcd controller output.
0044  * Encoder may provide a g_dv_timings() API to override these values
0045  * as needed.
0046  *
0047  *  Notes
0048  *  ------
0049  *  if_type should be used only by encoder manager and encoder.
0050  *  flags usage
0051  *     b0 (LSB) - hsync polarity, 0 - negative, 1 - positive
0052  *     b1       - vsync polarity, 0 - negative, 1 - positive
0053  *     b2       - field id polarity, 0 - negative, 1  - positive
