It probes the device tree -for sensor devices during the __init phase and registers them with the 'hwmon'. -'hwmon' populates the 'sysfs' tree having attribute files, each for a given -sensor type and its attribute data. - -All the nodes in the DT appear under "/ibm,opal/sensors" and each valid node in -the DT maps to an attribute file in 'sysfs'. The node exports unique 'sensor-id' -which the driver uses to make an OPAL call to the firmware. - -Usage notes ------------ -The driver is built statically with the kernel by enabling the config -CONFIG_SENSORS_IBMPOWERNV.
