gdsys IHS FPGA for CPU devices
|
|
|
|
The gdsys IHS FPGA is the main FPGA on gdsys CPU devices. This driver provides
|
|
support for enabling and starting the FPGA, as well as verifying working bus
|
|
communication.
|
|
|
|
Required properties:
|
|
- compatible: must be "gdsys,iocpu_fpga"
|
|
- reset-gpios: List of GPIOs controlling the FPGA's reset
|
|
- done-gpios: List of GPIOs notifying whether the FPGA's reconfiguration is
|
|
done
|
|
|
|
Example:
|
|
|
|
FPGA0 {
|
|
compatible = "gdsys,iocpu_fpga";
|
|
reset-gpios = <&PPCPCA 26 0>;
|
|
done-gpios = <&GPIO_VB0 19 0>;
|
|
};
