56 * Description:
57 * Structure holding timing and resolution information of a standard.
58 * Used by vpbe_device to set required non-standard timing in the
59 * venc when lcd controller output is connected to a external encoder.
60 * A table of timings is maintained in vpbe device to set this in
61 * venc when external encoder is connected to lcd controller output.
62 * Encoder may provide a g_dv_timings() API to override these values
63 * as needed.
64 *
65 * Notes
66 * ------
67 * if_type should be used only by encoder manager and encoder.
68 * flags usage
69 * b0 (LSB) - hsync polarity, 0 - negative, 1 - positive
70 * b1 - vsync polarity, 0 - negative, 1 - positive
71 * b2 - field id polarity, 0 - negative, 1 - positive
