In linux kernel since version 5 (release Date: 2019-03-03)  
This option enables support for monitoring sensors provided by the
On-Chip Controller (OCC) on a POWER8 processor. However, this driver
can only run on a baseboard management controller (BMC) connected to
the P8, not the POWER processor itself. Communications with the OCC are
established through I2C bus.

This driver can also be built as a module. If so, the module will be
called occ-p8-hwmon.
