+Xilinx LogiCORE Dynamic Function eXchange(DFX) AXI shutdown manager
+Softcore is compatible with the Xilinx LogiCORE pr-decoupler.

+The Dynamic Function eXchange AXI shutdown manager prevents AXI traffic
+from passing through the bridge. The controller safely handles AXI4MM
+and AXI4-Lite interfaces on a Reconfigurable Partition when it is
+undergoing dynamic reconfiguration, preventing the system deadlock
+that can occur if AXI transactions are interrupted by DFX

The Driver supports only MMIO handling. A PR region can have multiple
PR Decouplers which can be handled independently or chained via decouple/
decouple_status signals.
Required properties:

- clocks : input clock to IP
- clock-names : should contain "aclk"
