[PATCH v4 00/10] Add support for AD4080 ADC

[Antoniu Miclaus]

The AD4080 is a high-speed, low noise, low distortion, 20-bit, Easy
Drive, successive approximation register (SAR) analog-to-digital
converter (ADC). Maintaining high performance (signal-to-noise and
distortion (SINAD) ratio > 90 dBFS) at signal frequencies in excess
of 1 MHz enables the AD4080 to service a wide variety of precision,
wide bandwidth data acquisition applications.

This driver aims to be extended in the future to support multiple parts that are
not released yet:
    AD4081
    AD4082
    AD4083
    AD4084
    AD4085
    AD4086
    AD4087
    AD4088
