description: |
  The STMicroelectronics STM32 LVDS Display Interface Transmitter handles the
  LVDS protocol: it maps the pixels received from the upstream Pixel-DMA (LTDC)
  onto the LVDS PHY.

  It is composed of three sub blocks:
    - LVDS host: handles the LVDS protocol (FPD / OpenLDI) and maps its input
      pixels onto the data lanes of the PHY
    - LVDS PHY: parallelize the data and drives the LVDS data lanes
    - LVDS wrapper: handles top-level settings

  The LVDS controller driver supports the following high-level features:
    - FDP-Link-I and OpenLDI (v0.95) protocols
    - Single-Link or Dual-Link operation
    - Single-Display or Double-Display (with the same content duplicated on both)
    - Flexible Bit-Mapping, including JEIDA and VESA
    - RGB888 or RGB666 output
    - Synchronous design, with one input pixel per clock cycle
