From: "Edward A. James" <eajames@us.ibm.com>
This series adds two FSI-based device drivers. The OCC driver is dependent on
the SBEFIFO driver, as a user of it's in-kernel API. The in-kernel API provided
by the OCC driver will be used by a hwmon driver (on the lkml as "Add On-Chip
Controller (OCC) hwmon driver").
Changes since v2:
* Rename occ.c and occ.h to fsi-occ.c and fsi-occ.h
* Improved remove() ordering in both drivers.
* Added cancel functionality to OCC driver to make sure no xfrs started during
remove().
* Fix spin_unlock with spin_unlock_irq in OCC driver.
* Fix list_first_entry with list_first_entry_or_null in OCC worker function.
* Add OCC response definitions to OCC include file.
* Handle probe() failures better.
Changes since v1:
* Split bindings into separate patch and added SBEFIFO device binding
* Fixed #includes
* Fix SBEFIFO race condition between write() and poll_timer().
* Followed Rob's suggestion to just create one platform device for hwmon
driver, instead of using the device tree.
* Also check for "command in progress" response from OCC and try a while
