Subject: [PATCH v3 1/2] dt-bindings: iio: frequency: add admfm2000
Dual microwave down converter module with input RF and LO frequency
ranges from 0.5 to 32 GHz and an output IF frequency range from 0.1 to
8 GHz. It consists of a LNA, mixer, IF filter, DSA, and IF amplifier
for each down conversion path.

V2 -> V3: Adjusted indentation to resolve wrong indentation warning.
Changed node name to converter. Updated the descriptions to clarify
the properties.
V1 -> V2: Removed '|' after description. Specified the pins connected to
the GPIOs. Added additionalProperties: false. Changed node name to gpio.
Aligned < syntax with the previous syntax in the examples.
