As a side effect, it'll be nicer to add tracepoints to the gadget API. While at that, also fix Kconfig dependencies to avoid randconfig build failures.

So, if the xhci driver doesn't do firmware downloading (e.g. kernel configuration is CONFIG_USB_XHCI_PLATFORM=y and CONFIG_USB_XHCI_RCAR is not set), the reset of USB 3.0 host controller doesn't work correctly. Then, the host controller will cause long wait in xhci_reset() because the CMD_RESET bit of op_regs->command is not cleared for 10 seconds. So, this patch modifies the Kconfig to enable both CONFIG_USB_XHCI_PLATFORM and CONFIG_USB_XHCI_RCAR.

This controller, when loaded with external firmware, exposes an interface compliant with xHCI. This driver loads the firmware, starts the controller, and is able to service host-specific messages sent by the controller's firmware. The controller also supports USB device mode as well as powergating of the SuperSpeed and host-controller logic when not in use, but support for these is not yet implemented.

Many changes to the host side implementation of dwc2 have been done by Douglas Anderson. We also have USB 3.1 support added to the Gadget Framework and, because of that work, dwc3 got support to Synopsys new DWC_usb31 IP core. Other than these 2 important series, we also have the usual collection of non-critical fixes, Documentation updates, and minor changes all over the place. 2016-03-04T13:14:29+00:00 Arnd Bergmann arnd@arndb.de 2016-01-28T16:20:54+00:00 urn:sha1:d0fc35bc0889c7157527ed5758f54101ec015839 The USB_FSL_MPH_DR_OF symbol is used to ensure the code that interprets the DR device node is built whenever one of the two drivers (EHCI or UDC) for the platform is enabled. However, if CONFIG_USB is disabled and we only support gadget mode, this causes a Kconfig warning: warning: (USB_FSL_USB2) selects USB_FSL_MPH_DR_OF which has unmet direct dependencies (USB_SUPPORT && USB) We can avoid this warning by simply no longer using the symbol, and making sure we enter the drivers/usb/host/ directory when the UDC driver is enabled that needs the file, and then we use Makefile syntax to ensure the file is built-in if needed. There is currently a dependency on CONFIG_OF, but this is redundant, as we already know that this is set unconditionally for the platforms that use this driver.
