Moved, renamed, and deleted files
The original directory structure was scattered and unorganized. Changes are basically to make it look like kernel structure.

+Description
+-----------
+
+The LM95245 is an 11-bit digital temperature sensor 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 LM95245 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, but the hysteresis is common to all
+two channels.
+
+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.
