+Description
+-----------
+
+LM95234 is an 11-bit digital temperature sensor with a 2-wire System Management
+Bus (SMBus) interface and TrueTherm technology that can very accurately monitor
+the temperature of four remote diodes as well as its own temperature.
+The four remote diodes can be external devices such as microprocessors,
+graphics processors or diode-connected 2N3904s. The LM95234's TruTherm
+beta compensation technology allows sensing of 90 nm or 65 nm process
+thermal diodes accurately.
+
+All temperature values are given in millidegrees Celsius. Temperature
+is provided within a range of -127 to +255 degrees (+127.875 degrees for
+the internal sensor). Resolution depends on temperature input and range.
+
+Each sensor has its own maximum limit, but the hysteresis is common to all
+channels. The hysteresis is configurable with the tem1_max_hyst attribute and
+affects the hysteresis on all channels. The first two external sensors also
+have a critical limit.
+
+The lm95234 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.
