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