+description:
+  Microchip specific extensions or wrapper to the Synopsys Designware MIPI DSI.
+  The MIPI Display Serial Interface (DSI) Host Controller implements all
+  protocol functions defined in the MIPI DSI Specification. The DSI Host
+  provides an interface between the LCD Controller (LCDC) and the MIPI D-PHY,
+  allowing communication with a DSI-compliant display.
