# # USB Dual Role (OTG-ready) Controller Drivers # for silicon based on Mentor Graphics INVENTRA designs # comment "Enable Host or Gadget support to see Inventra options" depends on !USB && USB_GADGET=n # (M)HDRC = (Multipoint) Highspeed Dual-Role Controller config USB_MUSB_HDRC depends on USB || USB_GADGET tristate 'Inventra Highspeed Dual Role Controller (TI, ...)' 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 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". config USB_MUSB_SOC boolean depends on USB_MUSB_HDRC default y if ARCH_DAVINCI default y if ARCH_OMAP2430 default y if ARCH_OMAP34XX help Use a static file to describe how the controller is configured (endpoints, mechanisms, etc) on the current iteration of a given system-on-chip. comment "DaVinci 644x USB support" depends on USB_MUSB_HDRC && ARCH_DAVINCI comment "OMAP 243x high speed USB support" depends on USB_MUSB_HDRC && ARCH_OMAP2430 comment "OMAP 343x high speed USB support" depends on USB_MUSB_HDRC && ARCH_OMAP34XX comment "PUMA5 high speed USB support" depends on USB_MUSB_HDRC && ARCH_PUMA5 config USB_TUSB6010 boolean "TUSB 6010 support" depends on USB_MUSB_HDRC && !USB_MUSB_SOC && !ARCH_PUMA5 default y help 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 DMA controllers. choice prompt "Driver Mode" depends on USB_MUSB_HDRC help Dual-Role devices can support both host and peripheral roles, as well as a the special "OTG Device" role which can switch between both roles as needed. # use USB_MUSB_HDRC_HCD not USB_MUSB_HOST to #ifdef host side support; # OTG needs both roles, not just USB_MUSB_HOST. config USB_MUSB_HOST depends on USB bool "USB Host" help Say Y here if your system supports the USB host role. If it has a USB "A" (rectangular), "Mini-A" (uncommon), or "Mini-AB" connector, it supports the host role. (With a "Mini-AB" connector, you should enable USB OTG.) # use USB_GADGET_MUSB_HDRC not USB_MUSB_PERIPHERAL to #ifdef peripheral # side support ... OTG needs both roles config USB_MUSB_PERIPHERAL depends on USB_GADGET bool "USB Peripheral (gadget stack)" select USB_GADGET_MUSB_HDRC help Say Y here if your system supports the USB peripheral role. If it has a USB "B" (squarish), "Mini-B", or "Mini-AB" connector, it supports the peripheral role. (With a "Mini-AB" connector, you should enable USB OTG.) config USB_MUSB_OTG depends on USB && USB_GADGET && EXPERIMENTAL && !ARCH_DAVINCI_DM646x bool "Both host and peripheral: USB OTG (On The Go) Device" select USB_GADGET_MUSB_HDRC select USB_OTG 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. endchoice choice prompt "Reserve EP for" depends on USB && (USB_MUSB_HOST || USB_OTG) && USB_MUSB_HDRC && EXPERIMENTAL help Option for reserving additional endpoint for guaranteed support for at the least 1. one ISO device or 2. enable Interrupt Endpoint scheduling (reserve for INT devices) or 3. do not reserve any endpoint. One endpoint is reserved for handling BULK devices always by default. config MUSB_RSRV_NONE boolean "NONE" depends on USB && (USB_MUSB_HOST || USB_OTG) && USB_MUSB_HDRC bool help Either Schedule Interrupt Endpoint or reserve ISO endpoint is selected. config MUSB_SCHEDULE_INTR_EP boolean "Enabling Scheduling of Interrupt Endpoint (EXPERIMENTAL)" depends on USB && (USB_MUSB_HOST || USB_OTG) && USB_MUSB_HDRC && EXPERIMENTAL bool help Schedule Interrupt Endpoint resources for supporting multiple Interrupt URB's on a single INTR EP.

If you select Y then a Endpoint is reserved for handling ISO devices and will not be available for handling other types of traffic such as BULK, INT. endchoice # enable peripheral support (including with OTG) config USB_GADGET_MUSB_HDRC bool depends on USB_MUSB_HDRC && (USB_MUSB_PERIPHERAL || USB_MUSB_OTG) # default y # select USB_GADGET_DUALSPEED # select USB_GADGET_SELECTED # enables host support (including with OTG) config USB_MUSB_HDRC_HCD bool depends on USB_MUSB_HDRC && (USB_MUSB_HOST || USB_MUSB_OTG) select USB_OTG if USB_GADGET_MUSB_HDRC default y config MUSB_PIO_ONLY bool 'Disable DMA (always use PIO)' depends on USB_MUSB_HDRC default y if USB_TUSB6010 help All data is copied between memory and FIFO by the CPU. DMA controllers are ignored. Do not select 'n' here unless DMA support for your SOC or board is unavailable (or unstable).

Starting at level 3, per-transfer (urb, usb_request, packet, or dma transfer) tracing may kick in.
