The controller can decouple/disable the bridges 18 which prevents signal changes from passing through the bridge. The controller 19 can also couple / enable the bridges which allows traffic to pass through the 20 bridge normally. 21 Xilinx LogiCORE Dynamic Function eXchange(DFX) AXI shutdown manager Softcore 22 is compatible with the Xilinx LogiCORE pr-decoupler. The Dynamic Function 23 eXchange AXI shutdown manager prevents AXI traffic from passing through the 24 bridge. The controller safely handles AXI4MM and AXI4-Lite interfaces on a 25 Reconfigurable Partition when it is undergoing dynamic reconfiguration, 26 preventing the system deadlock that can occur if AXI transactions are 27 interrupted by DFX. 28 Please refer to fpga-region.txt and fpga-bridge.txt in this directory for 29 common binding part and usage. 30 31properties: 32 compatible: 33 oneOf: 34 - items: 35 - const: xlnx,pr-decoupler-1.00 36 - const: xlnx,pr-decoupler 37 - items: 38 - const: xlnx,dfx-axi-shutdown-manager-1.00 39 - const: xlnx,dfx-axi-shutdown-manager 40 41 reg: 42 maxItems: 1 43 44 clocks: 45 maxItems: 1 46 47 clock-names: 48 items: 49 - const: aclk 50 51required: 52 - compatible 53 - reg 54 - clocks 55 - clock-names 56 57unevaluatedProperties: false 58 59examples: 60 - | 61 fpga-bridge@100000450 { 62 compatible = "xlnx,pr-decoupler-1.00", "xlnx,pr-decoupler"; 63 reg = <0x10000045 0x10>; 64 clocks = <&clkc 15>; 65 clock-names = "aclk"; 66 }; 67... 68
