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.

V5 -> V6: Moved array of switch and attenuation GPIOs to the channel node.
Changed pin coords with friendly names. Removed Reviewed-by tag.
V4 -> V5: Added Reviewed-by tag.
V3 -> V4: Updated the description of the properties with multiple entries and
defined the order.
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.
