14description:
15  The LCD Controller (LCDC) consists of logic for transferring LCD image
16  data from an external display buffer to a TFT LCD panel. The LCDC has one
17  display input buffer per layer that fetches pixels through the single bus
18  host interface and a look-up table to allow palletized display
19  configurations.
