[PATCH 0/6] Add support for AD411x

[Dumitru Ceclan via B4 Relay]

This patch series adds support for the Analog Devices AD4111, AD4112,
 AD4114, AD4115, AD4116 within the existing AD7173 driver.

  The AD411X family encompasses a series of low power, low noise, 24-bit,
sigma-delta analog-to-digital converters that offer a versatile range of
specifications. They integrate an analog front end suitable for processing
fully differential/single-ended and bipolar voltage inputs.

- All ADCs have inputs with a precision voltage divider with a division
ratio of 10.
- AD4116 has 5 low level inputs without a voltage divider.
- AD4111 and AD4112 support current inputs (0 mA to 20 mA) using a 50ohm
shunt resistor.
