+Supported are LVDS versions (-11T, -19T) and parallel ones
+(-T, -1T, -7T, -20T).
+
+Required properties:
+- compatible: should be "urt,umsh-8596md-lvds" for LVDS versions,
+  "urt,umsh-8596md-parallel" for parallel ones.
+
+This binding is compatible with the simple-panel binding, which is specified
+in simple-panel.txt in this directory.
