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 v3:
-
* Non-nested dt-binding regulator support.
* PMBUS_REGULATOR_ONE("vout") -> PMBUS_REGULATOR_ONE("regulator").
New macro needs node-name to be matched.
Does that mean we can (and maybe should) drop the name parameter
of that macro ?
This isn't affecting this patch. If needed I'll do that separately.
Just asking.
Thanks,
Guenter

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.
