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

This driver implements support for Maxim MAX31730.

The MAX31730 temperature sensor monitors its own temperature and the
temperatures of three external diode-connected transistors. The operating
supply voltage is from 3.0V to 3.6V. Resistance cancellation compensates
for high series resistance in circuit-board traces and the external thermal
diode, while beta compensation corrects for temperature-measurement
errors due to low-beta sensing transistors.

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.
