+Device-Tree bindings for Synopsys DesignWare MIPI DSI host controller
+
+The controller is a digital core that implements all protocol functions
+defined in the MIPI DSI specification, providing an interface between
+the system and the MIPI DPHY, and allowing communication with a MIPI DSI
+compliant display.
+
+Required properties:
+ - #address-cells: Should be <1>.
+ - #size-cells: Should be <0>.
+ - compatible: The compatible string should be "fsl,imx6q-mipi-dsi" for
+ i.MX6q/sdl SoCs. For other SoCs, please refer to their specific
+ device tree binding documentations.
+ - reg: Represent the physical address range of the controller.
+ - interrupts: Represent the controller's interrupt to the CPU(s).
+ - clocks, clock-names: Phandles to the controller pll reference and
+ core configuration clocks, as described in [1].
+
+For more required properties, please refer to relevant device tree binding
+documentations which describe the controller embedded in specific SoCs.
+
+Required sub-nodes:
+ - A node to represent a DSI peripheral as described in [2].
+
+For more required sub-nodes, please refer to relevant device tree binding
+documentations which describe the controller embedded in specific SoCs.
