# # USB Dual Role (OTG-ready) Controller Drivers # for silicon based on Mentor Graphics INVENTRA designs # # (M)HDRC = (Multipoint) Highspeed Dual-Role Controller config USB_MUSB_HDRC tristate 'Inventra Highspeed Dual Role Controller (TI, ADI, ...)' depends on USB_GADGET help 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 families using this IP include DaVinci (35x, 644x ...), OMAP 243x, OMAP 3, and TUSB 6010. Analog Devices parts using this IP include Blackfin BF54x, BF525 and BF527. 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". if USB_MUSB_HDRC choice prompt "Platform Glue Layer" config USB_MUSB_DAVINCI tristate "DaVinci" depends on ARCH_DAVINCI_DMx depends on BROKEN config USB_MUSB_DA8XX tristate "DA8xx/OMAP-L1x" depends on ARCH_DAVINCI_DA8XX depends on BROKEN config USB_MUSB_TUSB6010 tristate "TUSB6010" depends on GENERIC_HARDIRQS config USB_MUSB_OMAP2PLUS tristate "OMAP2430 and onwards" depends on ARCH_OMAP2PLUS config USB_MUSB_AM35X tristate "AM35x" depends on ARCH_OMAP config USB_MUSB_DSPS tristate "TI DSPS platforms" config USB_MUSB_BLACKFIN tristate "Blackfin" depends on (BF54x && !BF544) || (BF52x && !
