Transferring BMI160 sample example to nRF9160 samples

Question

I am working on transferring BMI160 sample given in zephyr samples (\ncs\zephyr\samples\sensor\bmi160) to nrf sample (\ncs\nrf\samples\nrf9160\bmi160).

Below is the changed bits:

nrf9160_pca10090ns.overlay file

&spi3 {
        status = "ok";
	ss-pin = <10>;
        sck-pin = <11>;
        mosi-pin = <12>;
        miso-pin = <13>;
        spi-max-frequency = <8000000>;
		
	bmi160@0 {
		compatible = "bosch,bmi160";
		reg = <0>;
		spi-max-frequency = <8000000>;
		label = "BMI160";
	};
};

prj.conf file

CONFIG_SPI_3=y
CONFIG_SPI_3_NRF_SPIM=y

Main.c and CMake file are the same as provided in the sample and I get following error related to GPIO controller.

What could be the reason? Is it asking for an actual port and pin numbers? Thanks for your support.

Hi, 
 There is definitely some better way to solve this... but one option is to add the defines in dts_fixup.h , 
 # define DT_BOSCH_BMI160_0_INT_GPIOS_CONTROLLER DT_GPIO_P0_DEV_NAME 
 #define DT_BOSCH_BMI160_0_INT_GPIOS_PIN 30 // Some pin number
