1Samsung High Speed USB OTG controller
2-----------------------------
3
4The Samsung HSOTG IP can be found on Samsung SoCs, from S3C6400 onwards.
5It gives functionality of OTG-compliant USB 2.0 host and device with
6support for USB 2.0 high-speed (480Mbps) and full-speed (12 Mbps)
7operation.

12-----
13
14Required 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.
