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. + +[1] Documentation/devicetree/bindings/clock/clock-bindings.txt +[2] Documentation/devicetree/bindings/reset/reset.txt +[3] Documentation/devicetree/bindings/media/video-interfaces.txt +[4] Documentation/devicetree/bindings/graph.txt -- 1.9.1
