[PATCH v7 0/6] iio: adc: add support for ADE9000 Energy Monitoring IC

[Antoniu Miclaus <antoniu.miclaus@analog.com>]

This patch series adds support for the Analog Devices ADE9000, a highly
accurate, fully integrated, multiphase energy and power quality monitoring
device. The ADE9000 is capable of measuring energy consumption and power
quality parameters in industrial and commercial applications.

The series includes:

1. New IIO modifiers for power and energy measurement devices, including
   support for active/reactive/apparent power, RMS masurements.

2. Device tree bindings for the ADE9000, supporting waveform buffer
   configuration, phase configuration, and trigger settings.

3. Complete driver implementation supporting:
   - Multi-phase energy measurement (3-phase support)
   - Power quality monitoring (voltage swell/dip detection)
   - Waveform buffer capture with configurable triggering
   - Energy accumulation with configurable time windows
   - IIO buffer interface for continuous data streaming
   - Event-based notifications for power quality events

The driver provides a comprehensive interface for energy monitoring
applications through the IIO framework, enabling userspace applications
to monitor power consumption, quality, and waveform data.

The driver will be extended in the future to support multiple parts such as
ade9039.
