When operating in SPI target (slave) mode, the GENI SPI controller can
use an external GPIO to notify the SPI master about the target's
active state.
Is this active state meaning target is in ready state to communicate with master controller ?
I have already described the behaviour in the driver change.
When will it set this gpio ? can you describe little ?
Is additional explanation required in the DT binding as well?
As mark pointed, there is already ready-gpios so i use this.
Document the optional device-gpios property for the qcom,spi-geni-qcomseems bit generic name, it should describe the signal purpose, not the device. Something like handshake-gpios OR ready-gpios ?
and qcom,sa8255p-geni-spi bindings, restricted to spi-slave nodes.
