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.

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.

It defines some extra SW scheduling parameters for HW to minimize the scheduling effort for synchronous and interrupt endpoints. The parameters are put into reseved DWs of slot context and endpoint context. 2. Its IMODI unit for Interrupter Moderation register is 8 times as much as that defined in xHCI spec. 3.

USB: don't build PCI quirks if USB support isn't configured 2015-05-07T23:43:43+00:00 Alan Stern stern@rowland.harvard.edu 2015-04-22T16:11:59+00:00 3091fa77ffb1b91f4ac3ae005efe6213508f7ec1 The USB PCI quirks code gets built into the kernel whenever CONFIG_PCI is enabled, even if CONFIG_USB is not set. This can cause unnecessary messages to show up in the kernel log, such as "CONFIG_USB_XHCI_HCD is turned off, defaulting to EHCI" (which makes no sense when the kernel has been configured without host-side USB support).
