Changes in v9 from the cover letter
* drop P9 sensors patch. This patch was mainly included to demonstrate
why we abstracted out the sensor-specific code into the occ_p8 functions. However, since we haven't submitted the transfer protocol to the OCC for P9 yet, we shouldn't submit this unused P9 code yet.
* fix string access in hwmon read_string() function. Thanks Guenter.
* change parameter to const char ** in read_string() function to match
upcoming hwmon code.

Cover letter [PATCH linux v9 0/5] drivers: hwmon: Add On-Chip Controller driver
From: "Edward A. James" <[email protected]>
This patchset adds a hwmon driver to support the OCC (On-Chip Controller) on the IBM POWER8 and POWER9 processors, from a BMC (Baseboard Management Controller). The OCC is an embedded processor that provides real time power and thermal monitoring.
The driver provides an interface on a BMC to poll OCC sensor data, set user power caps, and perform some basic OCC error handling. It interfaces with userspace through hwmon.
The driver is currently functional only for the OCC on POWER8 chips. Communicating with the POWER9 OCC requries FSI support.

upcoming hwmon code.
