2 * USB device controllers have lots of quirks. Use these macros in
3 * gadget drivers or other code that needs to deal with them, and which
4 * autoconfigures instead of using early binding to the hardware.
5 *
6 * This SHOULD eventually work like the ARM mach_is_*() stuff, driven by
7 * some config file that gets updated as new hardware is supported.
8 * (And avoiding all runtime comparisons in typical one-choice configs!)
9 *
10 * NOTE: some of these controller drivers may not be available yet.
11 * Some are available on 2.4 kernels; several are available, but not
12 * yet pushed in the 2.6 mainline tree.
