This is an adapter card made for the 4.3", 800x480, LCD panel Seiko 43WVFIG. The LCD panel is a 24bit DPI bus, while the adapter card has two ports: 18-bit and 24-bit data input. For the 18-bit data input, the adapter card is demuxing some of the data lines, in order to feed all of the 24 lines needed by the LCD. This driver handles both this use-cases.
