+Faraday FOTG Dual role controller
+
+This OTG-capable host/device mode USB controller is found in Cortina Systems
+Gemini and other SoC products.
+On Gemini currently host mode is used
+
+Required properties:
+- compatible: should be one of:
+ "faraday,fotg210-dr"
+ "cortina,gemini-usb", "faraday,fotg210-dr"
+- reg: should contain one register range i.e. start and length
+- interrupts: description of the interrupt line
+
+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 "faraday,fotg210-dr" compatible
+ controllers. Can be "host" or "peripheral"
+ Default to "host" if not defined for backward compatibility.
+
+
+Required properties for "cortina,gemini-usb" compatible:
+- syscon: a phandle to the system controller to access PHY registers
+
+Optional properties for "cortina,gemini-usb" compatible:
+- cortina,gemini-mini-b: boolean property that indicates that a Mini-B
+ OTH connector is in use
+- wakeup-source: see power/wakeup-source.txt
+
+Example for Gemini:
+
+usb@68000000 {
+ compatible = "cortina,gemini-usb", "faraday,fotg210-dr";
+ reg = <0x68000000 0x1000>;
+ interrupts = <10 IRQ_TYPE_LEVEL_HIGH>;
+ clocks = <&cc 12>;
+ clock-names = "PCLK";
+ syscon = <&syscon>;
+ wakeup-source;
+};
