gdsys AXI busses of IHS FPGA devices
Certain gdsys IHS FPGAs offer a interface to their built-in AXI bus with which
the connected devices (usually IP cores) can be controlled via software.
Required properties:
- compatible: must be "gdsys,ihs_axi"
- reg: describes the address and length of the AXI bus's register map (within
the FPGA's register space)
Example:
fpga0_axi_video0 {
#address-cells = <1>;
#size-cells = <1>;
compatible = "gdsys,ihs_axi";
reg = <0x170 0x10>;
axi_dev_1 {
...
};
};
