+NLT Technologies Ltd. NL12880BC20 12.1" WXGA LVDS panel
+
+Note: The output format of the display can be configured via two
+ control pins (FRC, MSL). Depending on the strapping of those
+ pins the appropriate 'compatible' string has to be used.
+
+Required properties:
+- compatible: should be one of:
+ - "nlt,nl12880bc20-spwg-18" for SPWG (18bpp) FRC: Low or open, MSL: Low or open
+ - "nlt,nl12880bc20-spwg-24" for SPWG (24bpp) FRC: High, MSL: High
+ - "nlt,nl12880bc20-jeida" for JEIDA FRC: High, MSL: High
+
+This binding is compatible with the simple-panel binding, which is specified
+in simple-panel.txt in this directory.
