That's usually why we have SoC compatibles, so the description doesn't really add anything. Can you format with one valid compatible list per line: compatible : Should be one of: "aspeed,ast2500-uhci", "generic-uhci" "aspeed,ast2400-uhci", "generic-uhci" "generic-uhci" "platform-uhci" (deprecated) We should deprecate "generic-uhci" too IMO, but hardly anyone adds new UHCI controllers. > - reg : Should contain 1 register ranges(address and length) > - interrupts : UHCI controller interrupt > +- #ports: (optional) 1 cell, number of ports (overrides > + auto-detection which is needed among others on some Aspeed > + parts). > > Example: > > > > -- > To unsubscribe from this list: send the line "unsubscribe devicetree" in > the body of a message to majordomo@xxxxxxxxxxxxxxx > More majordomo info at http://vger.kernel.org/majordomo-info.html -- To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
