+description: |
+ The SN65DSI84 DSI to FlatLink bridge features a single channel MIPI D-PHY receiver
+ front-end configuration with 4 lanes per channel operating at 1 Gbps per lanes.
+ The bridge decodes MIPI DSI 18bpp RGB666 and 240bpp RG888 packets and converts
+ the formatted video data stream to a FlatLink compatible LVDS output operating
+ at pixel clocks operating from 25 MHx to 154 MHz, offering a Dual-Link LVDS,
+ Single-Link LVDS interface with four data lanes per link.

SN65DSI84 is a Single Channel DSI to Dual-link LVDS bridge from Texas Instruments. SN65DSI83, SN65DSI85 are variants of the same family of bridge controllers. Right now the bridge driver is supporting a single link, dual-link support requires to initiate I2C Channel B registers, so dt-bindings documented with single link LVDS.
