Subject: [PATCH 00/14] Add support for AD4080 ADC

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. Simplification of the
input anti-alias filter design can be accomplished by applying over-
sampling along with the integrated digital filtering and decimation to
reduce noise and lower the output data rate for applications that do
not require the lowest latency of the AD4080.
