We usually merge drivers for microwire, TI, Motorola ... etc into
drivers/spi as well. It's a good enough fit, the differences are very
small. This is how we configure mode from the PL022 driver platform data:
/**
* 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
};

That's pretty cool :-)

I think it's better if something like this is based on top of your patch
stack so as not to disrupt addition of new functionality. It'd be nice
if you could make the branch available once you push that stuff
to -next.
