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

This driver implements support for Texas Instruments TMP401, TMP411,
TMP431, TMP432, and TMP435 chips. These chips implement one or two
remote and one local temperature sensors. Temperature is measured in degrees
Celsius. Resolution of the remote sensor is 0.0625 degree. Local
sensor resolution can be set to 0.5, 0.25, 0.125 or 0.0625 degree (not
supported by the driver so far, so using the default resolution of 0.5
degree).

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

The TMP411 and TMP431 chips are compatible with TMP401. TMP411 provides
some additional features.

* Minimum and Maximum temperature measured since power-on, chip-reset

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.
