How to add new driver with dts support

[titusece]

Hello,
I would like to add my own device, so I wrote driver along with dts support based on gpio_dw.c driver code, now am getting build error, I suspect it could be due to dts. Could you help me to resolve the issue ?

My dts code:
test0: test@c0000000 {
		compatible = "snps,test";
		reg = <0x00 0xC0000000 0x00 0x2000>;
		label = "TEST0";
		interrupts = <GIC_SPI 2 IRQ_TYPE_LEVEL 0>;
		interrupt-parent = <&gic>;
		status = "okay";
};
		

My test driver:
		
#if DT_INST_IRQ_HAS_CELL(0, flags)
#define INST_0_IRQ_FLAGS DT_INST_IRQ(0, flags)
#else
#define INST_0_IRQ_FLAGS 0
#endif

static void test_hw_config_irq(const struct device* test)
{
        printk("%s:%d\n", __func__, __LINE__);
        const struct test_data_config* config = test->config;

        IRQ_CONNECT(DT_INST_IRQN(0),
                DT_INST_IRQ(0, priority), test_hw_isr,
                DEVICE_DT_INST_GET(0),
                INST_0_IRQ_FLAGS);
        irq_enable(config->irq_num);
}

static const struct test_data_config test_hw_config = {
        .irq_num = DT_INST_IRQN(0),
        .config_func = test_hw_config_irq,
};

static struct test_data_runtime test_hw_runtime = {
        .base_addr = DT_INST_REG_ADDR(0),
};

DEVICE_DT_INST_DEFINE(0,
        test_hw_initialize, NULL, &test_hw_runtime,
        &test_hw_config, PRE_KERNEL_1, 5,
        &api_funcs);

dts/bindings/test/snps,test.yaml

description: test node

compatible: "snps,test"

properties:
    reg:
      required: true

    interrupts:

Stumble upon the same problem when writing driver. Have you put the DT_DRV_COMPAT macro on top of your driver.c?

#define DT_DRV_COMPAT snps_test

This hooks the driver code with the device tree and makes DEVICE_DT_INST_* macros usable.
