H A Dfsi.txt1 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);
13 the fsi-master-* binding specifications.
16 represent the FSI slaves and their slave engines. As a basic outline:

19 /* top-level of FSI bus topology, bound to an FSI master driver and
20 * exposes an FSI bus */

13 The I2C Responder (I2CR) is a an I2C device that's connected to an FSI CFAM
14 (see fsi.txt). The I2CR translates I2C bus operations to FSI CFAM reads and
15 writes or SCOM operations, thereby acting as an FSI master.
