2*4882a593Smuzhiyun
3*4882a593SmuzhiyunThe Altera Freeze Bridge Controller manages one or more freeze bridges.
4*4882a593SmuzhiyunThe controller can freeze/disable the bridges which prevents signal
5*4882a593Smuzhiyunchanges from passing through the bridge.  The controller can also
6*4882a593Smuzhiyununfreeze/enable the bridges which allows traffic to pass through the
7*4882a593Smuzhiyunbridge normally.

9*4882a593SmuzhiyunRequired properties:
10*4882a593Smuzhiyun- compatible		: Should contain "altr,freeze-bridge-controller"
11*4882a593Smuzhiyun- regs			: base address and size for freeze bridge module
