1 | /* |
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. |
