- converted from .txt to .yaml
- dual-link lvds port added and implemented
- dsi data-lanes property removed, it will be picked
  from dsi0 ports
- VESA/JEIDA formats picked from panel-lvds dts
- proper indentation
- single-link and dual-link lvds description and
  examples are added
- license modified to (GPL-2.0-only OR BSD-2-Clause)

+description: |
+ This binding supports DSI to LVDS bridge TC358775
+
+ MIPI DSI-RX Data 4-lane, CLK 1-lane with data rates up to 800 Mbps/lane.
+ Video frame size:
+ Up to 1600x1200 24-bit/pixel resolution for single-link LVDS display panel
+ limited by 135 MHz LVDS speed
+ Up to WUXGA (1920x1200 24-bit pixels) resolution for dual-link LVDS display
+ panel, limited by 270 MHz LVDS speed.
