| 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 | |
