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>;
};
