1Altera FPGA/HPS Bridge Driver 2 3Required properties: 4- regs : base address and size for AXI bridge module 5- compatible : Should contain one of: 6 "altr,socfpga-lwhps2fpga-bridge", 7 "altr,socfpga-hps2fpga-bridge", or 8 "altr,socfpga-fpga2hps-bridge" 9- resets : Phandle and reset specifier for this bridge's reset 10- clocks : Clocks used by this module. 11 12Optional properties: 13- bridge-enable : 0 if driver should disable bridge at startup. 14 1 if driver should enable bridge at startup. 15 Default is to leave bridge in its current state. 16 17Example: 18 fpga_bridge0: fpga-bridge@ff400000 { 19 compatible = "altr,socfpga-lwhps2fpga-bridge"; 20 reg = <0xff400000 0x100000>; 21 resets = <&rst LWHPS2FPGA_RESET>; 22 clocks = <&l4_main_clk>; 23 bridge-enable = <0>; 24 }; 25 26 fpga_bridge1: fpga-bridge@ff500000 { 27 compatible = "altr,socfpga-hps2fpga-bridge"; 28 reg = <0xff500000 0x10000>; 29 resets = <&rst HPS2FPGA_RESET>; 30 clocks = <&l4_main_clk>; 31 bridge-enable = <1>; 32 }; 33 34 fpga_bridge2: fpga-bridge@ff600000 { 35 compatible = "altr,socfpga-fpga2hps-bridge"; 36 reg = <0xff600000 0x100000>; 37 resets = <&rst FPGA2HPS_RESET>; 38 clocks = <&l4_main_clk>; 39 }; 40
