Subject: [PATCH 1/2] dt-bindings: display: bridge: Add schema for Synopsys
 DW HDMI QP TX IP

Add dt-binding schema containing the common properties for the Synopsys
DesignWare HDMI QP TX controller.

Note this is not a full dt-binding specification, but is meant to be
referenced by platform-specific bindings for this IP core.

+description: |
+  This document defines device tree properties for the Synopsys DesignWare
+  HDMI 2.1 Quad-Pixel (QP) TX controller IP core.
+  It doesn't constitute a device tree binding specification by itself, but
+  is meant to be referenced by platform-specific device tree bindings.
+
+  When referenced from platform device tree bindings, the properties defined
+  in this document are defined as follows. The platform device tree bindings
+  are responsible for defining whether each property is required or optional.
