It consists of a LNA, mixer, IF filter, DSA, and IF amplifier for each down conversion path. Signed-off-by: Kim Seer Paller Reviewed-by: Conor Dooley --- V7 -> V8: Added adequate description for mixer mode property. Modified description for switch gpio property. V6 -> V7: Changed RF path mode property to boolean. 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.
