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.
