I've blatantly overrided this to a host only driver. These are the needed changes in DT to support both modes Note the -dr at the end of fotg210, to reflect this in an dual role device -- To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.htmldiff --git a/Documentation/devicetree/bindings/usb/faraday,fotg210.txt b/Documentation/devicetree/bindings/usb/faraday,fotg210.txt index cf06808303e2..862cda19e9d3 100644 --- a/Documentation/devicetree/bindings/usb/faraday,fotg210.txt +++ b/Documentation/devicetree/bindings/usb/faraday,fotg210.txt @@ -13,6 +13,9 @@ Required properties: Optional properties: - clocks: should contain the IP block clock - clock-names: should be "PCLK" for the IP block clock +- dr_mode : indicates the working mode for "fotg210-dr" compatible + controllers.
