| This binding supports DSI to LVDS bridge TC358775 |
| |
| MIPI DSI-RX Data 4-lane, CLK 1-lane with data rates up to 800 Mbps/lane. |
| Video frame size: |
| Up to 1600x1200 24-bit/pixel resolution for single-link LVDS display panel |
| limited by 135 MHz LVDS speed |
| Up to WUXGA (1920x1200 24-bit pixels) resolution for dual-link LVDS display |
| panel, limited by 270 MHz LVDS speed. |
