The NXP datasheet names the supply VDD, could we use vdd-supply here ? I also wouldn't call it ooptional (even if it effectively is from a DT point of view as the property isn't listed as required), given that the power supply isn't optional for the chip to function. How about the following ? vdd-supply: description: The voltage regulator powering to the VDD supply.
