1 | Samsung High Speed USB OTG controller |
| 2 | ----------------------------- | |
| 3 | ||
| 4 | The Samsung HSOTG IP can be found on Samsung SoCs, from S3C6400 onwards. | |
| 5 | It gives functionality of OTG-compliant USB 2.0 host and device with | |
| 6 | support for USB 2.0 high-speed (480Mbps) and full-speed (12 Mbps) | |
| 7 | operation. | |
| 8 | ||
| 9 | Currently only device mode is supported. | |
| 10 | ||
| 11 | Binding details | |
| 12 | ----- | |
| 13 | ||
| 14 | Required properties: | |
| 15 | - compatible: "samsung,s3c6400-hsotg" should be used for all currently | |
| 16 | supported SoC, | |
| 17 | - interrupt-parent: phandle for the interrupt controller to which the | |
| 18 | interrupt signal of the HSOTG block is routed, | |
| 19 | - interrupts: specifier of interrupt signal of interrupt controller, | |
| 20 | according to bindings of interrupt controller, | |
| 21 | - clocks: contains an array of clock specifiers: | |
| 22 | - first entry: OTG clock | |
| 23 | - clock-names: contains array of clock names: | |
| 24 | - first entry: must be "otg" | |
| 25 | - vusb_d-supply: phandle to voltage regulator of digital section, | |
| 26 | - vusb_a-supply: phandle to voltage regulator of analog section. | |

| 31 | hsotg@12480000 { | |
| 32 | compatible = "samsung,s3c6400-hsotg"; | |
| 33 | reg = <0x12480000 0x20000>; | |
| 34 | interrupts = <0 71 0>; | |
| 35 | clocks = <&clock 305>; | |
| 36 | clock-names = "otg"; | |
| 37 | vusb_d-supply = <&vusb_reg>; | |
| 38 | vusb_a-supply = <&vusbdac_reg>; | |
