-Xilinx LogiCORE Partial Reconfig Decoupler Softcore
-
-The Xilinx LogiCORE Partial Reconfig Decoupler manages one or more
-decouplers / fpga bridges.
-The controller can decouple/disable the bridges which prevents signal
-changes from passing through the bridge.  The controller can also
-couple / enable the bridges which allows traffic to pass through the
-bridge normally.
-
-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:
-- compatible		: Should contain "xlnx,pr-decoupler-1.00" followed by
-                          "xlnx,pr-decoupler" or
-                          "xlnx,dfx-axi-shutdown-manager-1.00" followed by
-                          "xlnx,dfx-axi-shutdown-manager"
-- regs			: base address and size for decoupler module
-- clocks		: input clock to IP
-- clock-names		: should contain "aclk"
-
-See Documentation/devicetree/bindings/fpga/fpga-region.txt and
-Documentation/devicetree/bindings/fpga/fpga-bridge.txt for generic bindings.
-
-Example:
-Partial Reconfig Decoupler:
-	fpga-bridge@100000450 {
-		compatible = "xlnx,pr-decoupler-1.00",
-			     "xlnx-pr-decoupler";
-		regs = <0x10000045 0x10>;
-		clocks = <&clkc 15>;
-		clock-names = "aclk";
-		bridge-enable = <0>;
-	};
-
-Dynamic Function eXchange AXI shutdown manager:
-	fpga-bridge@100000450 {
-		compatible = "xlnx,dfx-axi-shutdown-manager-1.00",
-			     "xlnx,dfx-axi-shutdown-manager";
-		regs = <0x10000045 0x10>;
-		clocks = <&clkc 15>;
-		clock-names = "aclk";
-		bridge-enable = <0>;
