     13  This binding supports transparent LVDS encoders and decoders that don't
     14  require any configuration.
     15
     16  LVDS is a physical layer specification defined in ANSI/TIA/EIA-644-A. Multiple
     17  incompatible data link layers have been used over time to transmit image data
     18  to LVDS panels. This binding targets devices compatible with the following
     19  specifications only.
