| D | fsi.txt | 1 FSI bus & engine generic device tree bindings
4 The FSI bus is probe-able, so the OS is able to enumerate FSI slaves, and
6 nodes to probed engines. This allows for fsi engines to expose non-probeable
7 busses, which are then exposed by the device tree. For example, an FSI engine
11 FSI masters may require their own DT nodes (to describe the master HW itself);
