Samsung High Speed USB OTG controller
-----------------------------
The Samsung HSOTG IP can be found on Samsung SoCs, from S3C6400 onwards.
It gives functionality of OTG-compliant USB 2.0 host and device with
support for USB 2.0 high-speed (480Mbps) and full-speed (12 Mbps)
operation.
Currently only device mode is supported.
Binding details
-----
Required properties:
- compatible: "samsung,s3c6400-hsotg" should be used for all currently
supported SoC,
- interrupt-parent: phandle for the interrupt controller to which the
interrupt signal of the HSOTG block is routed,
- interrupts: specifier of interrupt signal of interrupt controller,
according to bindings of interrupt controller,
- clocks: contains an array of clock specifiers:
- first entry: OTG clock
- clock-names: contains array of clock names:
- first entry: must be "otg"
- vusb_d-supply: phandle to voltage regulator of digital section,
- vusb_a-supply: phandle to voltage regulator of analog section.
Example
-----
hsotg@12480000 {
compatible = "samsung,s3c6400-hsotg";
reg = <0x12480000 0x20000>;
interrupts = <0 71 0>;
clocks = <&clock 305>;
clock-names = "otg";
vusb_d-supply = <&vusb_reg>;
vusb_a-supply = <&vusbdac_reg>;
};
