| 767 | * Internally TDA998x is using ITU-R BT.656 style sync but |
| 768 | * we get VESA style sync. TDA998x is using a reference pixel |
| 769 | * relative to ITU to sync to the input frame and for output |
| 770 | * sync generation. Currently, we are using reference detection |
| 771 | * from HS/VS, i.e. REFPIX/REFLINE denote frame start sync point |
| 772 | * which is position of rising VS with coincident rising HS. |
| 773 | * |
| 774 | * Now there is some issues to take care of: |
| 775 | * - HDMI data islands require sync-before-active |
| 776 | * - TDA998x register values must be > 0 to be enabled |
| 777 | * - REFLINE needs an additional offset of +1 |
| 778 | * - REFPIX needs an addtional offset of +1 for UYUV and +3 for RGB |
| 779 | * |
| 780 | * So we add +1 to all horizontal and vertical register values, |
| 781 | * plus an additional +3 for REFPIX as we are using RGB input only. |
