Is this active state meaning target is in ready state to communicate with master controller ?
Yes, you are right.

When will it set this gpio ? can you describe little ?
I have already described the behaviour in the driver change.
Is additional explanation required in the DT binding as well?

Document the optional device-gpios property for the qcom,spi-geni-qcom
seems bit generic name, it should describe the signal purpose, not the device. Something like handshake-gpios OR ready-gpios ?
As mark pointed, there is already ready-gpios so i use this.
and qcom,sa8255p-geni-spi bindings, restricted to spi-slave nodes.
