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, - 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>; };
