^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 1) Altera Freeze Bridge Controller Driver
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 2)
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 3) The Altera Freeze Bridge Controller manages one or more freeze bridges.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 4) The controller can freeze/disable the bridges which prevents signal
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 5) changes from passing through the bridge. The controller can also
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 6) unfreeze/enable the bridges which allows traffic to pass through the
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 7) bridge normally.
