[PATCH 0/2] Add support for AD4113

[PATCH 0/2] Add support for AD4113

[Dumitru Ceclan]

This patch series adds support for the AD4113 ADC within the existing
AD7173 driver.

The AD4113 is a low power, low noise, 16-bit, Σ-Δ analog-to-digital
converter (ADC) that integrates an analog front end (AFE) for four
fully differential or eight single-ended inputs.

The part is not released yet and the documentation is not public.
Register map is identical to AD4114. Particularities of this model are
no temperature sensor and 8 VINx inputs.

You should highlight why it is incompatible from existing devices, it's
not clear from the description/diff.
