- help
- The most notable feature of USB OTG is support for a
- "Dual-Role" device, which can act as either a device
- or a host. The initial role choice can be changed
- later, when two dual-role devices talk to each other.
-
- At this writing, the OTG support in this driver is incomplete,
- omitting the mandatory HNP or SRP protocols. However, some
- of the cable based role switching works. (That is, grounding
- the ID pin switches the controller to host mode, while leaving
- it floating leaves it in peripheral mode.)
-
- Select this if your system has a Mini-AB connector, or
- to simplify certain kinds of configuration.
-
- To implement your OTG Targeted Peripherals List (TPL), enable
- USB_OTG_WHITELIST and update "drivers/usb/core/otg_whitelist.h"
- to match your requirements.
