Which device drivers are used with a SPI device?

I have inherited a project using a BF518 and uClinux.  The SPORT channel 0 is currently connected to a DAC.  The SPORT channel 1 currently has a connector which will be used to connect to multiple off board ADCs.  The ADC chosen is the LMP90100 which has a SPI interface.


Based upon the version information I believe that uClinux is 2009R1.1


These are my questions

1. What options need to be chosen and changes made (kconfig, arch/blackfin/mach-bf518/boards, etc) to allow SPORT channel 1 to be used as a SPI port?

2. What device drivers are needed for this to work?

3. Is it better to have the SPORT emulate a SPI?

4. If so what changes and device drivers are needed for this to work?
