Altera FPGA To SDRAM Bridge Driver
|
|
|
|
Required properties:
|
|
- compatible : Should contain "altr,socfpga-fpga2sdram-bridge"
|
|
|
|
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 current state.
|
|
|
|
Example:
|
|
fpga_bridge3: fpga-bridge@ffc25080 {
|
|
compatible = "altr,socfpga-fpga2sdram-bridge";
|
|
reg = <0xffc25080 0x4>;
|
|
bridge-enable = <0>;
|
|
};
