The additional six LCDIF data signals required for a 24-bit interface are mapped to module-specific pins whose location is not fixed across the Colibri family and which may not be available at all. Generic Colibri carrier boards can therefore only rely on an 18-bit interface. Set the LCDIF bus-width property accordingly. A 24-bit interface can still be used by a specific carrier and module combination by overriding the property in the carrier board device tree.
