Subject: [PATCH 0/7] drivers/hwmon: Add On-Chip Controller (OCC) hwmon driver

From: "Edward A. James" <eajames@...ibm.com>

This series adds a hwmon driver to support the OCC on POWER8 and POWER9
processors. The OCC is an embedded processor that provides realtime power and
thermal monitoring and management.

This driver has two different platform drivers as a "base" for the
hwmon stuff, as the means of communicating with the OCC on P8 and P9 is
completely different. For P8, the driver is an I2C client driver. For P9 the
driver is an FSI-based OCC client driver, and uses the OCC driver in-kernel
API.

There was a previous version of this driver that wasn't written with the
differences in communication methods between the two versions in mind. This
driver has been considerably simplified.

Edward A. James (7):
  drivers/hwmon: Add On-Chip Controller (OCC) hwmon driver
  drivers/hwmon/occ: Add command transport method for P8 and P9
  drivers/hwmon/occ: Parse OCC poll response
  drivers/hwmon/occ: Add sensor types and versions
  drivers/hwmon/occ: Add sensor attributes and register hwmon device
  drivers/hwmon/occ: Add non-hwmon attributes
  drivers/hwmon/occ: Add error handling
