Subject: [PATCH v3 1/8] dt-bindings: display: Add bindings for LVDS bus-timings

Dual-LVDS connections need markers in the DT, this patch adds
some common documentation to be referenced by both panels and
bridges.

+description: |
+  This document defines device tree properties common to LVDS and dual-LVDS
+  interfaces, where a dual-LVDS interface is a dual-link connection with even
+  pixels traveling on one connection, and with odd pixels traveling on the other
+  connection.
+  This document doesn't constitue a device tree binding specification by itself
+  but is meant to be referenced by device tree bindings.
+  When referenced from panel or bridge device tree bindings, the properties
+  defined in this document are defined as follows. The panel and bridge device
+  tree bindings are responsible for defining whether each property is required
+  or optional.
+
+properties:
+  dual-lvds-even-pixels:
+    type: boolean
+    description:
+      This property is specific to an input port of a sink device. When
+      specified, it marks the port as recipient of even-pixels.
+
+  dual-lvds-odd-pixels:
+    type: boolean
+    description:
+      This property is specific to an input port of a sink device. When
+      specified, it marks the port as recipient of odd-pixels.
