2 * This is used to for host and peripheral modes of the driver for
3 * Inventra (Multidrop) Highspeed Dual-Role Controllers: (M)HDRC.
4 *
5 * Board initialization should put one of these into dev->platform_data,
6 * probably on some platform_device named "musb-hdrc". It encapsulates
7 * key configuration differences between boards.
