Kernel driver ltc2991
=====================
Supported chips:
* Analog Devices LTC2991
Prefix: 'ltc2991'
Addresses scanned: I2C 0x48 - 0x4f
Datasheet: https://www.analog.com/media/en/technical-documentation/data-sheets/2991ff.pdf
Authors:

Description
-----------
This driver supports hardware monitoring for Analog Devices LTC2991 Octal I2C
Voltage, Current and Temperature Monitor.
The LTC2991 is used to monitor system temperatures, voltages and currents.
Through the I2C serial interface, the eight monitors can individually measure
supply voltages and can be paired for differential measurements of current sense
resistors or temperature sensing transistors. Additional measurements include
internal temperatureand internal VCC.

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.
