How to define an interrupt pin for SPIM in devicetree

[peter_liu]

I'd like to add an interrupt pin for a SPIM device. (eg. in the following spi_dev:)

&spi3 {

compatible = "nordic,nrf-spim";
cs-gpios = <&gpio0 0xf GPIO_ACTIVE_LOW>;

spi_dev: spi-master@0 {
reg = <0>;

};
};

and how to get the pin in c code by devicetree API?

are there any example codes?

Hi,

You will need a devicetree binding for your spim device. The interrupt pin is usually called "int-gpios" in the spim device bindings I found in the sdk.

May I ask which device you are using? Then I can try to find examples of bindings/overlays/drivers for similar devices.
