The paths added back in 4.13 weren't quite correct. The in reality the files documented lived under /sys/devices/../fsi0/rescan /sys/devices/../fsi0/break /sys/devices/../fsi0/slave@00:00/term /sys/devices/../fsi0/slave@00:00/raw In 5.5 with the addition of the FSI class they move to /sys/devices/../fsi-master/fsi0/rescan /sys/devices/../fsi-master/fsi0/break /sys/devices/../fsi-master/fsi0/slave@00:00/term /sys/devices/../fsi-master/fsi0/slave@00:00/raw This is closer to how the (incorrect) documentation described them.

Description:
|
|
Sends an FSI BREAK command on a master's communication
|
|
link to any connnected slaves. A BREAK resets connected
|
|
device's logic and preps it to receive further commands
|
|
from the master.

|
Description:
|
|
Sends an FSI terminate command from the master to its
|
|
connected slave. A terminate resets the slave's state machines
|
|
that control access to the internally connected engines. In
|
|
addition the slave freezes its internal error register for
|
|
debugging purposes. This command is also needed to abort any
|
|
ongoing operation in case of an expired 'Master Time Out'
|
|
timer.
