+LDB-XGA is an example for the resolution of your LVDS panel. You can input the actual resolution of your LVDS panel here, such as 800x480, 1024x768, etc. The system will accomplish the corresponding parameters automatically. If the panel has problem to be activated, you may need to check the panel datasheet to configure the panel related parameters. The LVDS video mode database is stored in linux-3.2.0/drivers/video/da8xx-fb.c. You can add a new one for your LVDS panel.

+The definition of da8xx_panel in linux-3.2.0/ drivers/video/da8xx-fb.c: The name field is optional. If you input this value, it can be used in U-Boot environment settings. The refresh field is the screen refresh frame rate, such as 60Hz, 70Hz. The resolution can be filled in the xres & yres fields. The pixel clock (pixclock) is equaled to 10ʌ12 /(Total horizontal line * Total vertical line * DCLK). For example, the total horizontal line is 1344 DCLK, and total vertical number is 806 horizontal lines. The frame rate is 60 MHz. Therefore, we can get 10 12 /(1344*806*60) = 15385.<br/>The margin values can be seen as front porch & back porch.<br/>The sync_len means pulse width.<br/>The sync value indicates the sync polarity (low or high).
