The vcc-supply property is deprecated, once it does not really exist as none of the devices describe any power input with that name. VCC is also misleading as it sounds like the input power supply, but it is being used as an external voltage reference, which should be called VREF. Certain devices require vref-supply to be available once an internal reference voltage is absent. For correct operation vdd and vlogic supplies are required.
