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.
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!)
10 * NOTE: some of these controller drivers may not be available yet.

135 * @gadget: the controller being driven
137 * Return a 2-digit BCD value associated with the peripheral controller,
138 * suitable for use as part of a bcdDevice value, or a negative error code.
140 * NOTE: this convention is purely optional, and has no meaning in terms of

142 * gadget driver firmware -- maybe a more formal revision ID -- feel free.
144 * Hosts see these bcdDevice numbers, and are allowed (but not encouraged!)
145 * to change their behavior accordingly. For example it might help avoiding
