Neat, I guess. How would a PlayStation controller be connected to SPI though? Do the original pins map to SPI somehow?

Yes, see the commit message and the driver itself.

It looks like this driver only supports the DualShock v1 protocol right now. The PS2 pad is backwards-compatible with that, but IIRC in native mode also has pressure-sensitive front buttons and the sticks report 10-bit values instead of 8.
