Hi Rob,

Is it ok for you with this tree file:

Documentation/devicetree/bindings/arm/stm32/stm32.txt
Documentation/devicetree/bindings/arm/stm32/stm32-syscon.txt
	With stm32-syscon.txt:

---------------------------------------------------
STMicroelectronics STM32 Platforms System Controller

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: system-config@50020000 {
		compatible = "st,stm32mp157-syscfg", "syscon";
		reg = <0x50020000 0x400>;
	};
---------------------------------------------------

Do we need to update also all MCU family (stm32f4, stm32h7, stm32f7) 
property to be coherent ?

Thanks for your feedback.

Christophe.
