The Nomadik has a variant of the PL110 known as "Color LCD Controller" LCDC. This variant has the same bit ordering as the DRM subsystem (in difference from the other variants) and adds a few bits for the control of 5551, 565 etc in the control register. Notably it also adds a packed RGB888 24BPP mode. We add support by detecting this variant and also adding a small plug-in that will mux the LCDC out if the ASIC happens to be muxed to the other graphics controller (they are mutually exclusive).
