| 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>; |
| }; |
