/*
* USB device controllers have lots of quirks. Use these macros in
* gadget drivers or other code that needs to deal with them, and which
* autoconfigures instead of using early binding to the hardware.
*
* This SHOULD eventually work like the ARM mach_is_*() stuff, driven by
* some config file that gets updated as new hardware is supported.
* (And avoiding all runtime comparisons in typical one-choice configs!)
*
* NOTE: some of these controller drivers may not be available yet.
* Some are available on 2.4 kernels; several are available, but not
* yet pushed in the 2.6 mainline tree.
