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.
