| Say Y here if your system has a dual role high speed USB |
| controller based on the Mentor Graphics silicon IP. Then |
| configure options to match your silicon and the board |
| it's being used with, including the USB peripheral role, |
| or the USB host role, or both. |
| |
| Texas Instruments parts using this IP include DaVinci 644x, |
| OMAP 243x, OMAP 343x, and TUSB 6010. |
| |
| If you do not know what this is, please say N. |
| |
| To compile this driver as a module, choose M here; the |
| module will be called "musb_hdrc". |

| The TUSB 6010 chip, from Texas Instruments, connects a discrete |
| HDRC core using a 16-bit parallel bus (NOR flash style) or VLYNQ |
| (a high speed serial link). It can use system-specific external |

| 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. |
