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 HDMI TX registers. + +- reg-io-width: Width of the registers specified by the reg property. The + value is expressed in bytes and must be equal to 1 or 4 if specified. The + register width defaults to 1 if the property is not present. + +- interrupts: Reference to the DWC HDMI TX interrupt. + +- clocks: References to all the clocks specified in the clock-names property + as specified in Documentation/devicetree/bindings/clock/clock-bindings.txt. + +- clock-names: The DWC HDMI TX uses the following clocks. + + - "iahb" is the bus clock for either AHB and APB (mandatory). + - "isfr" is the internal register configuration clock (mandatory). + - "cec" is the HDMI CEC controller main clock (optional). + +- ports: The connectivity of the DWC HDMI TX with the rest of the system is + expressed in using ports as specified in the device graph bindings defined + in Documentation/devicetree/bindings/graph.txt. The numbering of the ports + is platform-specific. |
