This change populates device tree nodes for scanned FSI slaves and engines. If the master populates ->of_node of the FSI master device, we'll look for matching slaves, and under those slaves we'll look for matching engines. This means that FSI drivers will have their ->of_node pointer populated if there's a corresponding DT node, which they can use for further device discover. Presence of device tree nodes is optional, and only required for fsi device drivers that need extra properties, or subordinate devices, to be enumerated.

This option enables a FSI hub master driver. Hub is a type of FSI
|
|
master that is connected to the upstream master via a slave. Hubs
|
|
allow chaining of FSI links to an arbitrary depth. This allows for
|
|
a high target device fanout.
