How do I extra the gpio phandle form a lis3dh device to the C code?

[J0sh1101]

I have a lis3dh sensor where I want to configure the interrupts. I am currently struggling to extract the information from the irq-gpios phandle to the c driver. I went through the troubleshooting page for the device tree and found a website explanation that said it should work, but I am still unable to compile the code. 

I have a overlay define like this: 

&i2c0 {  
    mysensor: mysensor@18{
        compatible = "st,lis3dh";
        status = "okay";
        reg = < 0x18 >;
        irq-gpios = <&gpio0 11 GPIO_ACTIVE_HIGH>, <&gpio1 4 GPIO_ACTIVE_HIGH>;
    };
};

My driver tries to extract the data gpio information like this:

#define I2C1_NODE DT_NODELABEL(mysensor)

static const struct i2c_dt_spec dev_i2c = I2C_DT_SPEC_GET(I2C1_NODE);


//const struct gpio_dt_spec int1 = DT_IRQN_BY_IDX(DT_NODELABEL(mysensor), 0);
//const struct gpio_dt_spec int1 = GPIO_DT_SPEC_INST_GET_BY_IDX_COND(DT_NODELABEL(mysensor), irq_gpios, 0);
//const struct gpio_dt_spec int1 = GPIO_DT_SPEC_INST_GET_BY_IDX_OR(DT_NODELABEL(mysensor), irq_gpios, 0, {});
//const struct gpio_dt_spec int1 = DT_GPIO_CTLR_BY_IDX(I2C1_NODE, irq_gpios, 0);
const struct gpio_dt_spec int1 = DT_GPIO_CTLR_BY_IDX(I2C1_NODE, irq_gpios, 0);

I have received an error like this:

I can access the I2C node, that I defined but the gpio struct?

Thanks for the help!

Do you get any error when you try to a pristine build? 

I have seen in the past doing a pristine build or deleting the build folder might help. 

You can also check if it is included in the generated .dts with status okey.

I do not get any errors, but I get a warning saying that it cannot enabled:

-- Including generated dts.cmake file: C:/nordic_play_workfolder/LIS3DH/build_nrf52840_dk/zephyr/dts.cmake

warning: LIS2DH (defined at drivers/sensor/lis2dh/Kconfig:6) was assigned the value 'y' but got the
value 'n'. Check these unsatisfied dependencies: DT_HAS_ST_LIS2DH_ENABLED (=n). See
http://docs.zephyrproject.org/latest/kconfig.html#CONFIG_LIS2DH and/or look up LIS2DH in the
menuconfig/guiconfig interface. The Application Development Primer, Setting Configuration Values,
and Kconfig - Tips and Best Practices sections of the manual might be helpful too.

I wonder if it might not be the intellisense giving a false positive. I have seen it reported with the same driver before on devzone. I did acutally get the same warning yesterday with the following config. 

//prj.conf
CONFIG_I2C=y
CONFIG_SENSOR=y
CONFIG_LIS2DH=y
CONFIG_LIS2DH_TRIGGER_GLOBAL_THREAD=y

//devicetree
&i2c1 {
    compatible = "nordic,nrf-twim";
    status = "okay";
    lis3dh: lis3dh@18 {
        compatible = "st,lis2dh","st,lis2dh12", "st,lis3dh" ;
        status = "okay";
        reg = <0x18>;
        irq-gpios = <&gpio0 2 GPIO_ACTIVE_HIGH>,<&gpio1 15 GPIO_ACTIVE_HIGH>;
        disconnect-sdo-sa0-pull-up;
    };
};
 
/{
    aliases {
        accel0 = &lis3dh;
    };
}; 

But when I started VScode today it gave me no warning. I would recommend checking if the sensor is included in the generated devicetree with status okay
