+Properties:
+ - compatible : should contain two values. First value must be :
+ - " st,stm32mp157-syscfg " - for stm32mp157 based SoCs,
+ second value must be always "syscon".
+ - reg : offset and length of the register set.
+
+ Example:
+ syscfg: syscon@50020000 {
+ compatible = "st,stm32mp157-syscfg", "syscon";
+ reg = <0x50020000 0x400>;
