now that we have the udc class, we can allow multiple gadget controller drivers to be compiled as modules. This will allow for distro-like kernels for embedded devices. With this patch, I managed to build an x86 kernel with support for many of the controllers enabled: CONFIG_USB_FUSB300=m CONFIG_USB_R8A66597=m CONFIG_USB_M66592=m CONFIG_USB_AMD5536UDC=m CONFIG_USB_CI13XXX_PCI=m CONFIG_USB_NET2272=m CONFIG_USB_NET2280=m CONFIG_USB_GOKU=m CONFIG_USB_LANGWELL=m CONFIG_USB_EG20T=m Also an ARM kernel with support for many controllers: CONFIG_USB_FUSB300=m CONFIG_USB_OMAP=m CONFIG_USB_R8A66597=m CONFIG_USB_GADGET_MUSB_HDRC=m CONFIG_USB_M66592=m CONFIG_USB_NET2272=m CONFIG_USB_DUMMY_HCD=m The next step would be to get rid of the direct access to arch/ and mach/ directories on some gadget controllers so that we can build all of them without depending on their respective ARCH_* symbols.

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.
