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

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.
