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