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.

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	};
