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.

Yours,
Linus Walleij
