Hence I'm fine with this going via the dt tree.

feature-domains is an optional property that allows a peripheral to refer to one or more feature domain controller(s). Description of this property is added to all peripheral binding files of the peripheral under the STM32 System Bus. It allows an accurate representation of the hardware, where various peripherals are connected to this firewall bus. The firewall can then check the peripheral accesses before allowing it to probe.
