Wrtting sensor driver in zephyr, DT_INST_FOREACH_STATUS_OKAY problem.

Question

Hello, 
 I'm trying to writte a sensordriver for the nuvoton NAU7802 ADC in Zephyr using the drivers/sensor API. Here are the most important (I believe) parts of my code: 
 In nau7802.h: 
 struct nau7802_data {
	const struct device *dev;
	uint8_t resolution;
	uint8_t sample;
	uint8_t ldo;
	uint8_t sps;
	uint8_t gain;
};

struct nau7802_config {
	struct i2c_dt_spec bus;
	uint16_t config;
	uint8_t resolution;
	uint8_t sample;
	uint8_t ldo;
	uint8_t sps;
	uint8_t gain;
#ifdef CONFIG_NAU7802_TRIGGER
	const struct gpio_dt_spec gpio_drdy;
#endif /* CONFIG_NAU7802_TRIGGER */	
}; 
 In nau7802.c: 
 #define DT_DRV_COMPAT nuvoton_nau7802

static const struct sensor_driver_api nau7802_driver_api = {
	.attr_set = nau7802_attr_set,
	.attr_get = nau7802_attr_get,
#ifdef CONFIG_NAU7802_TRIGGER
	.trigger_set = nau7802_trigger_set,
#endif
	.sample_fetch = nau7802_sample_fetch,
	.channel_get = nau7802_channel_get,
};

#define NAU7802_DEVICE_INIT(inst) \
	static struct nau7802_data drv_data_##inst; \
	static const struct nau7802_config drv_config_##inst = { \
 .bus = I2C_DT_SPEC_INST_GET(inst), \
 .config = DT_INST_PROP(inst, config), \
 .resolution = DT_INST_PROP(inst, resolution), \
 .sample = DT_INST_PROP(inst, sample), \
 .ldo = DT_INST_PROP(inst, ldo), \
 .sps = DT_INST_PROP(inst, sps), \
 .gain = DT_INST_PROP(inst, gain), \
 COND_CODE_1(DT_INST_NODE_HAS_PROP(inst, gpio_drdy), \
 (NAU7802_CFG_IRQ(inst)), ()) \
	}; \
	DEVICE_DT_INST_DEFINE(inst, \
 &nau7802_begin, \
 NULL, \
 &drv_data_##inst, \
 &drv_config_##inst, \
 POST_KERNEL, \
 CONFIG_SENSOR_INIT_PRIORITY,	\
 &nau7802_driver_api);

DT_INST_FOREACH_STATUS_OKAY(NAU7802_DEVICE_INIT) 
 And I've added the kconfig and yaml files too,and the device node in my overlay file. However, I'm getting an error when compiling: 
 devicetree_unfixed.h:11825:37: error: 'DT_N_S_soc_S_i2c_40004000_S_nau7802_2a_P_resolution' 
undeclared here (not in a function); did you mean 'DT_N_S_soc_S_i2c_40004000_S_nau7802_2a_P_reg_EXISTS'?
11825 | #define DT_N_INST_0_nuvoton_nau7802 DT_N_S_soc_S_i2c_40004000_S_nau7802_2a 
 I think the problem is in my data and config structs but I can't find where is my mistake. Please, I would appreciate any insights. 
 
 Thanks in advance, bestr egards.
