Confusion about number of SPIs
In the specifications for the Up2 it says there are two SPI busses on the HAT connector: SPI0 with 2 CS and SPI1 with 3 CS.
However, only SPI0 is listed in the pin configuration and that's also the only one available in /dev/ (where it is called spidev1.x for some reason).
What's with the other SPI? Are there just no drivers, or is it really not exposed on the HAT (if so, why is it listed in the wiki)?
Is there some way to get a second SPI bus working on the HAT (or exHAT)? Other than doing software SPI of course.
