- * 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.
