[libopenstm32-devel] USB driver abstraction

[Gareth M. <ga...@bl...>]

Hi All

I'm planning on adding support for the OTG_FS hardware to the usb
stack soon, but this requires some restructuring to keep the interface
clean.

I've put all the functions in usb_f103.c into a driver structure, and
a pointer to this structure is passed to usbd_init().  The idea is to
add another driver structure for each hardware implementation.
An application developer then only needs to change the driver pointer
when porting across hardware implementations.

Please have a look at my repo on github and let me know what you
think of this approach:
git://github.com/gsmcmullin/libusbdev.git

Any comments would be appreciated.  If everybody likes this it can be
pulled into the main repo.

Regards,
Gareth
