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 *
David Brownell1c05ad42006-01-25 08:45:59 -08006 * This SHOULD eventually work like the ARM mach_is_*() stuff, driven by
Linus Torvalds1da177e2005-04-16 15:20:36 -07007 * some config file that gets updated as new hardware is supported.
David Brownell1c05ad42006-01-25 08:45:59 -08008 * (And avoiding all runtime comparisons in typical one-choice configs!)
Linus Torvalds1da177e2005-04-16 15:20:36 -07009 *
10 * NOTE: some of these controller drivers may not be available yet.
David Brownell7f9985c2007-05-08 21:01:30 -070011 * Some are available on 2.4 kernels; several are available, but not
12 * yet pushed in the 2.6 mainline tree.
