From: "Edward A. James" <eajames@xxxxxxxxxx> 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 interface, 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. The OCC driver is on the LKML (latest https://lkml.org/lkml/2017/7/5/633). Changes since v1: * Remove wait loop in P9 code, as that is now handled by FSI OCC driver. * Removed dt binding documentation for P9, FSI OCC driver will probe OCC hwmon driver automatically. * Moved OCC response code definitions to the OCC include file. * Fixed includes. * Changed some structure fields to __beXX as that is what they are. * Changed some errnos. * Removed some dev_err(). * Refactored P8 code a bit to use #defined addresses and magic values, and changed "goto retry" to a loop. * Refactored error handling a bit.
