Altera FPGA/HPS Bridge Driver
Required properties:
- regs : base address and size for AXI bridge module
- compatible : Should contain one of:
"altr,socfpga-lwhps2fpga-bridge",
"altr,socfpga-hps2fpga-bridge", or
"altr,socfpga-fpga2hps-bridge"
- resets : Phandle and reset specifier for this bridge's reset
- clocks : Clocks used by this module.
Optional properties:
- bridge-enable : 0 if driver should disable bridge at startup.
1 if driver should enable bridge at startup.
Default is to leave bridge in its current state.
Example:
fpga_bridge0: fpga-bridge@ff400000 {
compatible = "altr,socfpga-lwhps2fpga-bridge";
reg = <0xff400000 0x100000>;
resets = <&rst LWHPS2FPGA_RESET>;
clocks = <&l4_main_clk>;
bridge-enable = <0>;
};
fpga_bridge1: fpga-bridge@ff500000 {
compatible = "altr,socfpga-hps2fpga-bridge";
reg = <0xff500000 0x10000>;
resets = <&rst HPS2FPGA_RESET>;
clocks = <&l4_main_clk>;
bridge-enable = <1>;
};
fpga_bridge2: fpga-bridge@ff600000 {
compatible = "altr,socfpga-fpga2hps-bridge";
reg = <0xff600000 0x100000>;
resets = <&rst FPGA2HPS_RESET>;
clocks = <&l4_main_clk>;
};
