nrfx twis drivers on nrf9160 (Zephyr)

Question

Hello,

I want to use I2C slave on nrf9160, but there is no I2C slave driver implementation.

So I read that instead of this, I can use nrfx twis drivers on nrf9160.

I followed this thread https://github.com/zephyrproject-rtos/zephyr/issues/21445 to use nrfx twis drivers on zephyr.

prj.conf

CONFIG_TRUSTED_EXECUTION_NONSECURE=y
CONFIG_SERIAL=y
CONFIG_UART_INTERRUPT_DRIVEN=y
CONFIG_NRFX_TWIS=y
CONFIG_NRFX_TWIS0=y

nrf9160_pca10090ns.overlay

&i2c0 {
	compatible = "nordic,nrf-twis";
	status = "okay";
	sda-pin = < 19 >;
	scl-pin = < 18 >;
};

When I open the project with these prj.conf and overlay file, I am getting this error:

If I remove the compatible = "nordic,nrf-twis"; from overlay file, then there is no error but twis does not work.

Also while adding the IRQ handler,

        IRQ_CONNECT(DT_NORDIC_NRF_I2C_I2C_2_IRQ_0, 
                            DT_NORDIC_NRF_I2C_I2C_2_IRQ_0_PRIORITY, 
                            nrfx_isr, nrfx_twis_2_irq_handler, 0);

I have these above options available.

But I should use:

IRQ_CONNECT(DT_NORDIC_NRF_TWIS_I2C_0_IRQ_0,
	    DT_NORDIC_NRF_TWIS_I2C_0_IRQ_0_PRIORITY,
	    nrfx_isr, nrfx_twis_0_irq_handler, 0);

But using this, I get the error.

How to solve this problem?
