+Altera Freeze Bridge Controller Driver
+
+The Altera Freeze Bridge Controller manages one or more freeze bridges.
+The controller can freeze/disable the bridges which prevents signal
+changes from passing through the bridge. The controller can also
+unfreeze/enable the bridges which allows traffic to pass through the
+bridge normally.
+
+Required properties:
+- compatible : Should contain "altr,freeze-bridge-controller"
+- regs : base address and size for freeze bridge module
+
+Optional properties:
+- bridge-enable : 0 if driver should disable bridge at startup
+ 1 if driver should enable bridge at startup
+ Default is to leave bridge in current state.
+
+Example:
+ freeze-controller@100000450 {
+ compatible = "altr,freeze-bridge-controller";
+ regs = <0x1000 0x10>;
+ bridge-enable = <0>;
