^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 10) Description
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 11) -----------
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 12)
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 13) This driver implements reading the platform sensors data like temperature/fan/
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 14) voltage/power for 'POWERNV' platform.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 15)
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 16) The driver uses the platform device infrastructure. It probes the device tree
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 17) for sensor devices during the __init phase and registers them with the 'hwmon'.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 18) 'hwmon' populates the 'sysfs' tree having attribute files, each for a given
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 19) sensor type and its attribute data.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 20)
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 21) All the nodes in the DT appear under "/ibm,opal/sensors" and each valid node in
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 22) the DT maps to an attribute file in 'sysfs'. The node exports unique 'sensor-id'
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 23) which the driver uses to make an OPAL call to the firmware.

^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 26) -----------
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 27) The driver is built statically with the kernel by enabling the config
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 28) CONFIG_SENSORS_IBMPOWERNV. It can also be built as module 'ibmpowernv'.
