yes, it is MVEBU SoC, I'm using orion_spi driver. The connection is
unidirectional SPI.

You mean the example in the binding description? I can add there
something like:
Usage example for full FPGA configuration:
fpga-region0 {
compatible = "fpga-region";
fpga-mgr = <&fpga_mgr_spi>;
#address-cells = <0x1>;
#size-cells = <0x1>;
};
&spi1 {
status = "okay";
fpga_mgr_spi: fpga-mgr@0 {
compatible = "xlnx,fpga-slave-serial";
reg = <0>;
spi-max-frequency = <60000000>;
spi-cpha;
done-gpios = <&gpio0 7 GPIO_ACTIVE_HIGH>;
prog_b-gpios = <&gpio0 26 GPIO_ACTIVE_LOW>;
};
};
Thanks,
Anatolij
