[PATCH v2 0/2] Add support for LT3074 low voltage linear regulator

From: Cedric Encarnacion
Date: Tue Feb 25 2025 - 08:03:57 EST


Introduce hardware monitoring and regulator support for LT3074. The
component is an ultrafast, ultralow noise 3A, 5.5V dropout linear
regulator with a PMBus serial interface that allows telemetry for
input/output voltage, output current, and die temperature. It has a
single channel and requires a bias voltage which can be monitored via
manufacturer-specific registers.

Changes in v2:
* Separated dt-binding for LT3074.
* Added __maybe_unused attribute to of_device_id. This addresses kernel
test robot warning.
* Added entry to MAINTAINERS.
