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.
