307c478bd9Sstevel@tonic-gate *
317c478bd9Sstevel@tonic-gate * For each temperature-device class node, it does the following:
327c478bd9Sstevel@tonic-gate * - Create cpu and cpu-ambient temperautre-sensor class nodes.
337c478bd9Sstevel@tonic-gate * - Create "devfs-path" property under each temperature-sensor class node
347c478bd9Sstevel@tonic-gate * - Create "Temperature" volatile property under these nodes.
357c478bd9Sstevel@tonic-gate * - Create various temperature threshold properties under each node.
367c478bd9Sstevel@tonic-gate * - Create "Temperature" and "AmbientTemperature" volatile properties
377c478bd9Sstevel@tonic-gate * under corresponding "cpu" class node.
387c478bd9Sstevel@tonic-gate *
397c478bd9Sstevel@tonic-gate * For the "fan-control" node, it does the following:
407c478bd9Sstevel@tonic-gate * - Create system-fan node
417c478bd9Sstevel@tonic-gate * - Create "devfs-path" property under "fan" class node
427c478bd9Sstevel@tonic-gate * - Create "Speed" volatile propery under each node.
437c478bd9Sstevel@tonic-gate * - Create "SpeedUnit" property under each node.
447c478bd9Sstevel@tonic-gate *
457c478bd9Sstevel@tonic-gate * Access to sensor/fan properties is protected by the envpicl_rwlock
467c478bd9Sstevel@tonic-gate * readers/writer lock. This lock is held as a reader while trying to
477c478bd9Sstevel@tonic-gate * access any volatile sensor/fan property, and held as a writer lock
487c478bd9Sstevel@tonic-gate * while trying to create or destroy sensor/fan nodes and properties.
