Subject[PATCH/RFC 04/12] dt-bindings: display: Add bindings for Advantech IDK-2121WR
Date
This panel is handled through the generic lvds-panel bindings,
so only needs its additional compatible specified.

Some panel specific documentation can be found here:
https://buy.advantech.eu/Displays/Embedded-LCD-Kits-High-Brightness/model-IDK-2121WR-K2FHA2E.htm
