23 * struct vpbe_enc_mode_info
24 * @name: ptr to name string of the standard, "NTSC", "PAL" etc

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
