Date:		May 2017

KernelVersion:  4.12

Contact:        cbostic@linux.vnet.ibm.com

Description:

                Initiates a FSI master scan for all connected slave devices

		on its links.



What:           /sys/bus/platform/devices/fsi-master/break

Date:		May 2017

KernelVersion:  4.12

Contact:        cbostic@linux.vnet.ibm.com

		link to any connnected slaves.  A BREAK resets connected

		device's logic and preps it to receive further commands

		from the master.



What:           /sys/bus/platform/devices/fsi-master/slave@00:00/term

Date:		May 2017

KernelVersion:  4.12

Contact:        cbostic@linux.vnet.ibm.com

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.
