This adds a starting point for processing and defining generic
bindings used by DSI panels. We just define one single bool
property to force the panel into video mode for now.

+description: |
+  This document defines device tree properties common to DSI, Display
+  Serial Interface panels. It doesn't constitue a device tree binding
+  specification by itself but is meant to be referenced by device tree
+  bindings.
+
+  When referenced from panel device tree bindings the properties defined in
+  this document are defined as follows. The panel device tree bindings are
+  responsible for defining whether each property is required or optional.
+
+properties:
+
+  enforce-video-mode:
+    type: boolean
+    description:
+      The best option is usually to run a panel in command mode, as this
+      gives better control over the panel hardware. However for different
+      reasons like broken hardware, missing features or testing, it may be
+      useful to be able to force a command mode-capable panel into video
+      mode.
