Since the MFD driver is what creates the TLL struct devices, the MFD driver will have the TLL struct device pointers. Something like omap_usbhost_get_tll_device() and omap_usbhost_put_tll_device(). One other thing. Not sure what the correct generic name prefix for these functions should be, since I don't know the provenance of the USBHOST IP block; but maybe the function prefix should be something like 'ti_usbhost' instead, to indicate that it isn't OMAP-specific? You would know better than I. - Paul -- To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
