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

The Texas Instruments TMP108 implements one temperature sensor. An alert pin
can be set when temperatures exceed minimum or maximum values plus or minus a
hysteresis value. (This driver does not support interrupts for the alert pin,
and the device runs in comparator mode.)

The sensor is accurate to 0.75C over the range of -25 to +85 C, and to 1.0
degree from -40 to +125 C. Resolution of the sensor is 0.0625 degree. The
operating temperature has a minimum of -55 C and a maximum of +150 C.
Hysteresis values can be set to 0, 1, 2, or 4C.

The TMP108 has a programmable update rate that can select between 8, 4, 1, and
0.5 Hz.

By default the TMP108 reads the temperature continuously. To conserve power,
the TMP108 has a one-shot mode where the device is normally shut-down. When a
one shot is requested the temperature is read, the result can be retrieved,
and then the device is shut down automatically. (This driver only supports
continuous mode.)

The driver provides the common sysfs-interface for temperatures (see
Documentation/hwmon/sysfs-interface.rst under Temperatures).

Implementation Notes

This generated page is the file-by-file coverage layer; curated subsystem chapters should link here when they synthesize a multi-file control flow.
Core OS pages should be promoted from atlas-only to deep-reviewed when they explain data structures, invariants, locking, lifecycle, and C implementation snippets.
Driver-family pages are intentionally pattern-oriented unless they are part of the selected PCIe/NVMe representative device path.
