This SSP Controller supports a number of serial communication methods. Namely: /** * 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) */ ... and as such cannot be registered using of_register_spi_devices. Instead it can be registered simply as a primecell device.
