[PATCH v2 0/6] iio: adc: ade9000: add ADE9430 support

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

The ADE9430 is a polyphase energy metering device from the same family as
the ADE9000. It is register-compatible with the ADE9000 but omits the
on-chip dip/swell detection and has no on-chip digital integrator; it
relies on an external analog integrator for Rogowski coil current sensors.

This series adds ADE9430 support to the existing ade9000 driver, reusing
the dip/swell-less channel table introduced for the ADE9078 and adding a
matching chip_info for the ADE9430 full-scale codes. A precursor patch
gates the DICOEFF register write behind a has_digital_integrator chip_info
flag so it is skipped on parts without an on-chip digital integrator.

Patches 1 and 2 are standalone fixes carried with this series. Patch 1
corrects the ADE9000 full-scale RMS/PCF codes to the same family-A values
the ADE9430 uses. Patch 2 fixes the DIPC event never being handled or
cleared, found by the sashiko review of v1. Both carry Fixes: tags and can
be applied independently of the rest of the series.

Changes in v2:
- new patch: fix the DIPC event never being handled or cleared, found by
  the sashiko review of v1 (patch 2).
- new precursor patch: gate the DICOEFF write behind a has_digital_integrator
  chip_info flag, split out of the ADE9430 support patch.
- reuse ade9078_channels for the ADE9430 instead of adding a duplicate
  channel table.
- reword the documentation intro to "The supported parts are..." so it does
  not need updating for each new part.
