-Description
------------
-
-LM95235 and LM95245 are 11-bit digital temperature sensors with a 2-wire System
-Management Bus (SMBus) interface and TruTherm technology that can monitor
-the temperature of a remote diode as well as its own temperature.
-The chips can be used to very accurately monitor the temperature of
-external devices such as microprocessors.
-
-All temperature values are given in millidegrees Celsius. Local temperature
-is given within a range of -127 to +127.875 degrees. Remote temperatures are
-given within a range of -127 to +255 degrees. Resolution depends on
-temperature input and range.
-
-Each sensor has its own critical limit. Additionally, there is a relative
-hysteresis value common to both critical limits. To make life easier to
-user-space applications, two absolute values are exported, one for each
-channel, but these values are of course linked. Only the local hysteresis
-can be set from user-space, and the same delta applies to the remote
-hysteresis.
-
-The lm95245 driver can change its update interval to a fixed set of values.
-It will round up to the next selectable interval. See the datasheet for exact
-values. Reading sensor values more often will do no harm, but will return
-'old' values.
