+STM32 BOOSTER - Booster for ADC analog input switches
+
+Some STM32 devices embed a 3.3V booster supplied by Vdda, that can be used
+to supply ADC analog input switches.
+
+Required properties:
+- compatible: Should be one of:
+ "st,stm32h7-booster"
+ "st,stm32mp1-booster"
+- st,syscfg: Phandle to system configuration controller.
+- vdda-supply: Phandle to the vdda input analog voltage.
+
+Example:
+ booster: regulator-booster {
+ compatible = "st,stm32mp1-booster";
+ st,syscfg = <&syscfg>;
+ vdda-supply = <&vdda>;
+ };
