Yeah well: /** * enum ssp_interface - interfaces allowed for this SSP Controller * @SSP_INTERFACE_MOTOROLA_SPI: Motorola Interface * @SSP_INTERFACE_TI_SYNC_SERIAL: Texas Instrument Synchronous Serial * interface * @SSP_INTERFACE_NATIONAL_MICROWIRE: National Semiconductor Microwire * interface * @SSP_INTERFACE_UNIDIRECTIONAL: Unidirectional interface (STn8810 * &STn8815 only) */ enum ssp_interface { SSP_INTERFACE_MOTOROLA_SPI, SSP_INTERFACE_TI_SYNC_SERIAL, SSP_INTERFACE_NATIONAL_MICROWIRE, SSP_INTERFACE_UNIDIRECTIONAL }; If that is what you mean then yes. All of the protols are "SPI type" though.
