ChangeSet 1.1290.15.22, 2004/03/17 15:07:08-08:00, david-b@pacbell.net [PATCH] USB: add "gadget_chips.h" This adds standard gadget_is_*() calls. Gadget drivers using those calls can get rid of some inlined #ifdefs, and will also be able to do more "late binding" to their hardware. Define gadget_is_*() calls, to help do late binding to USB controllers. Current gadget drivers expect to know at compile time what hardware they'll bind to. That's not very friendly to a generic PDA distro, which might prefer to defer such choices to run time. These macros let drivers change that code from inlined #ifdefs (ugh) to normal C statements (looks much nicer), so making those "what hardware" policy choices at run time gets easier. drivers/usb/gadget/gadget_chips.h | 57 ++++++++++++++++++++++++++++++++++++++ 1 files changed, 57 insertions(+) diff -Nru a/drivers/usb/gadget/gadget_chips.h b/drivers/usb/gadget/gadget_chips.h --- /dev/null Wed Dec 31 16:00:00 1969 +++ b/drivers/usb/gadget/gadget_chips.h Wed Mar 17 15:48:21 2004 @@ -0,0 +1,57 @@ +/* + * USB device controllers have lots of quirks.
