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 | * | |
1c05ad44 | 6 | * This SHOULD eventually work like the ARM mach_is_*() stuff, driven by |
1da177e4 | 7 | * some config file that gets updated as new hardware is supported. |
1c05ad44 | 8 | * (And avoiding all runtime comparisons in typical one-choice configs!) |

10 | * NOTE: some of these controller drivers may not be available yet. | |
7f9985c2 DB |
11 | * Some are available on 2.4 kernels; several are available, but not |
12 | * yet pushed in the 2.6 mainline tree. | |
