The bit field definitions for usb-types usb-recipient, and directions are itself defined in usb_defs.h; so i thought of keeping their combination just below it, so that it would not be difficult to reference. Please let me know if you want me to move them to include/usb.h > > Best regards, > Marek Vasut

The headers are mess and will eventually need cleanup too, not in this patchset of course. Best regards, Marek Vasut

Macros defining bmRequestType field of USB device request, given in table 9.2 USB 2.0 spec, are rather generic macros which can be further used by other Host controller stacks. So moving them to usb_defs header.
