- A pinctrl state named "default" for each ADC channel may be defined to set
inX ADC pins in mode of operation for analog input on external pin.
+- booster-supply: Phandle to the embedded booster regulator that can be used
+ to supply ADC analog input switches on stm32h7 and stm32mp1.
+- vdd-supply: Phandle to the vdd input voltage. It can be used to supply ADC
