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