+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
