+description: |
+ Firewall properties provide the possible firewall bus controller
+ configurations for a device.
+ Bus firewall controllers are typically used to control if a hardware
+ block can perform read or write operations on bus.
+ The contents of the firewall bus configuration properties are defined by
+ the binding for the individual firewall controller device.
+
+ The first configuration 'firewall-0' or the one named 'default' is
+ applied before probing the device itself.
