- Subject: [PATCH 14/18] usb: host: add DT bindings for faraday fotg2
- This adds device tree bindings for the Faraday FOTG2
- dual-mode host controller.

- 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;
- +};
