ILI7807S is a DSI display controller used to drive MIPI-DSI panels. The DLC DLC0697 1080x1920 LCD panel is based on this controller.
The panel requires a reset GPIO, backlight enable GPIO, I/O voltage supply (vddi), positive LCD bias supply (avdd) and negative LCD bias supply (avee). The panel operates in video burst mode with four data lanes using RGB888 pixel format.
