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;
|
|
};
