Description
-----------

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.

which applies to all limits. This register can be written by writing into
temp1_crit_hyst. Other hysteresis attributes are read-only.

If the BIOS has configured the sensor for automatic temperature management, it
is likely that it has locked the registers, i.e., that the temperature limits
cannot be changed.
