+title: Common Bus Firewall consumer binding
+
+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.
