-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>;
- };
