+Synopsys DesignWare MIPI DSI host controller
+============================================
+
+This document defines device tree properties for the Synopsys DesignWare MIPI
+DSI host controller. It doesn't constitue 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.
+
+- reg: Memory mapped base address and length of the DWC MIPI DSI registers.
+
+- clocks: References to all the clocks specified in the clock-names property
+  as specified in [1].
+
+- clock-names: The DWC MIPI DSI host uses the following clocks.
+
+  - "pclk" is the peripheral clock for either AHB and APB (mandatory).
+  - "ref" is the pll reference clock (mandatory).
+
+- resets: References to all the resets specified in the reset-names property
+  as specified in [2]. (optional)
+
+- reset-names: string reset name, must be "apb" if used. (optional)
+
+- ports: The connectivity of the DWC MIPI DSI host controller
+  with the rest of the system is expressed in using ports as specified in the
+  device graph bindings in [3] & [4]. The numbering of the ports
+  is platform-specific.
