The adf4378 provides only one output channel. Therefore there is only one gpio available to enable the output. Reflect that into the bindings using property conditions. Add product link for the adf4378.

The ADF4377 is a high performance, ultralow jitter, dual output integer-N
|
|
phased locked loop (PLL) with integrated voltage controlled oscillator (VCO)
|
|
ideally suited for data converter and mixed signal front end (MxFE) clock
|
|
applications.
