ChangeLog v1->v2:
|
|
- Changed "OTH" to "OTG"
|
|
- Collected Rob's ACK.
|
|
- I don't see any problem with these bindings, but IIRC Hans
|
|
had some reservations for the OTG mode, maybe we can strip
|
|
some properties like the mini-usb thing and use as a starter
|
|
so we can add host mode at least?

+Faraday FOTG Host controller
|
|
+
|
|
+This OTG-capable USB host controller is found in Cortina Systems
|
|
+Gemini and other SoC products.
|
|
+
|
|
+Required properties:
|
|
+- compatible: should be one of:
|
|
+ "faraday,fotg210"
|
|
+ "cortina,gemini-usb", "faraday,fotg210"
|
|
+- 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
|
|
+
|
|
+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
|
|
+ OTG connector is in use
|
|
+- wakeup-source: see power/wakeup-source.txt
|
|
+
|
|
+Example for Gemini:
|
|
+
|
|
+usb@68000000 {
|
|
+ compatible = "cortina,gemini-usb", "faraday,fotg210";
|
|
+ reg = <0x68000000 0x1000>;
|
|
+ interrupts = <10 IRQ_TYPE_LEVEL_HIGH>;
|
|
+ clocks = <&cc 12>;
|
|
+ clock-names = "PCLK";
|
|
+ syscon = <&syscon>;
|
|
+ wakeup-source;
|
|
+};
