The OCC is an embedded processor that provides realtime power and thermal monitoring and management. The series also adds a "bus" driver to handle atomic communication between the service processor and the OCC on a POWER9 chip. This communication takes place over FSI bus to the SBE (Self-Boot engine) FIFO, which in turn communicates with the OCC. The driver for the SBEFIFO is already in linux-next as an FSI client driver. For POWER8 OCCs, communication between the service processor and the OCC is achieved over I2C bus. Changes since v3: * Add the FSI OCC driver. * Pull the sysfs attribute code into it's own file for cleanliness. * Various fixes for attribute creation and integer overflow. Changes since v2: * Add sysfs_notify for the error and throttling attributes when change is detected. * Removed occs_present counting of devices bound. * Improved remove() of P9 driver to avoid bad behavior with relation to OCC driver when unbound. * Added default cases (return EINVAL) for all sensor show functions. * Added temperature fault sensor. * Added back dt binding documentation for P9 to address checkpatch warning. * Added occs_present attribute from the poll response. 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.
