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.
11 * Some are available on 2.4 kernels; several are available, but not
12 * yet pushed in the 2.6 mainline tree.

151 * usb_gadget_controller_number - support bcdDevice id convention
152 * @gadget: the controller being driven
154 * Return a 2-digit BCD value associated with the peripheral controller,
155 * suitable for use as part of a bcdDevice value, or a negative error code.
157 * NOTE: this convention is purely optional, and has no meaning in terms of
158 * any USB specification. If you want to use a different convention in your
159 * gadget driver firmware -- maybe a more formal revision ID -- feel free.
161 * Hosts see these bcdDevice numbers, and are allowed (but not encouraged!)
162 * to change their behavior accordingly. For example it might help avoiding
165 static inline int usb_gadget_controller_number(struct usb_gadget
*gadget
