21   adi,dc-dc-mode:
25       Mode of operation of the dc-to-dc converter
27       In this mode, the AD5758 circuitry senses the output voltage and
29       requirements plus an optimized headroom voltage for the output buffer.
32       In this mode, the VDPC+ voltage is user-programmable to a fixed level
33       that needs to accommodate the maximum output load required.
35       The output of the DAC core is either converted to a current or
36       voltage output at the VIOUT pin. Only one mode can be enabled at
44       Depending on the selected output mode (voltage or current) one of the
