[PATCH v1 1/2] dt-bindings: iio: adc: Add MAX14001

[Marilene Andrade Garcia]

Add device-tree documentation for MAX14001/MAX14002 ADCs.
The MAX14001/MAX14002 are isolated, single-channel analog-to-digital
converters with programmable voltage comparators and inrush current
control optimized for configurable binary input applications.
