-This driver implements support for JEDEC JC 42.4 compliant temperature sensors.
+This driver implements support for JEDEC JC 42.4 compliant temperature sensors,
+which are used on many DDR3 memory modules for mobile devices and servers. Some
+systems use the sensor to prevent memory overheating by automatically throttling
+the memory controller.
The driver auto-detects the chips listed above, but can be manually instantiated
to support other JC 42.4 compliant chips.
