     59      In older device trees this can be the accidental name for the analog
     60      supply on the VCCA pin, and in that case the deprecated vddo-supply is
     61      used for the digital power supply.

     66      the vdd-supply represents VCCA instead of VDD. Implementers should first
     67      check for this property, and if it is present assume that the vdd-supply
     68      represents the analog supply.
