-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
-
-See Documentation/devicetree/bindings/fpga/fpga-bridge.txt for generic bindings.

- freeze-controller@100000450 {
