dt-binding: Add DSI/LVDS TC358775 bridge bindings
- license modified to (GPL-2.0-only OR BSD-2-Clause) - single-link and dual-link lvds description and examples are added - proper indentation - VESA/JEIDA formats picked from panel-lvds dts - dsi data-lanes property removed, it will be picked from dsi0 ports - dual-link lvds port added and implemented - converted from .txt to .yaml Signed-off-by: Vinay Simha BN <simhavcs@gmail.com> Reviewed-by: Sam Ravnborg <sam@ravnborg.org> Reviewed-by: Rob Herring <robh@kernel.org> Signed-off-by: Sam Ravnborg <sam.ravnborg@gmail.com> Link: https://patchwork.freedesktop.org/patch/msgid/1594388491-15129-1-git-send-email-simhavcs@gmail.com
