This isn't the FSI device per-se actually. This is a node below the "sbefifo" FSI device. The SBE fifo is the mechanism by which we communicate with the OCC. The sbefifo doesn't really define a "bus", it's mostly used from userspace directly via /dev/sbefifo* to perform various tasks in the chip, but it happens to also provide the in-kernel transport for the OCC commands.
