Kernel driver ltc2992
=====================
Supported chips:
* Linear Technology LTC2992
Prefix: 'ltc2992'
Datasheet: https://www.analog.com/media/en/technical-documentation/data-sheets/ltc2992.pdf
Author: Alexandru Tachici <alexandru.tachici@analog.com>
Description
-----------
This driver supports hardware monitoring for Linear Technology LTC2992 power monitor.
LTC2992 is a rail-to-rail system monitor that measures current,
voltage, and power of two supplies.
Two ADCs simultaneously measure each supply's current. A third ADC monitors
the input voltages and four auxiliary external voltages.
Sysfs entries

inX_input Measured voltage.
inX_lowest Minimum measured voltage.
inX_highest Maximum measured voltage.
inX_min Minimum voltage allowed.
inX_max Maximum voltage allowed.
inX_min_alarm An undervoltage occurred. Cleared on read.
inX_max_alarm An overvoltage occurred. Cleared on read.
currX_input Measured current.
currX_lowest Minimum measured current.
currX_highest Maximum measured current.
currX_min Minimum current allowed.

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.
