| 102 | The most notable feature of USB OTG is support for a |
| 103 | "Dual-Role" device, which can act as either a device |
| 104 | or a host. The initial role choice can be changed |
| 105 | later, when two dual-role devices talk to each other. |
| 106 | |
| 107 | At this writing, the OTG support in this driver is incomplete, |
| 108 | omitting the mandatory HNP or SRP protocols. However, some |
| 109 | of the cable based role switching works. (That is, grounding |
| 110 | the ID pin switches the controller to host mode, while leaving |
| 111 | it floating leaves it in peripheral mode.) |
| 112 | |
| 113 | Select this if your system has a Mini-AB connector, or |
| 114 | to simplify certain kinds of configuration. |
| 115 | |
| 116 | To implement your OTG Targeted Peripherals List (TPL), enable |
| 117 | USB_OTG_WHITELIST and update "drivers/usb/core/otg_whitelist.h" |
