+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 optional property is used or not.
+
+- reg: Memory mapped base address and length of the DesignWare MIPI DSI
+  host controller registers. (mandatory)
+
+- clocks: References to all the clocks specified in the clock-names property
+  as specified in [1]. (mandatory)
+
+- clock-names: "pclk" is peripheral clock for either AHB and APB. (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)
+
+- panel or bridge node: see [3]. (mandatory)
