Sensor channel and attribute doesn't fit

[mejtejt]

Hi,
If I want to use external RTC which operates through I2C, would you suggest using sensor driver api's like sensor_driver_api?
In that case I can't use neither one of the sensor_channel enums for example in function m4lt62_channel_get, but I have to read seconds, minutes, hours etc..
Do you have some other approaches in mind ?

You can add sensor-specific channels, attributes, and triggers. See e.g. https://github.com/zephyrproject-rtos/zephyr/blob/master/include/drivers/sensor/mcux_acmp.h

Another solution could be to use the counter API similar to how the DS3231 RTC driver is implemented: https://github.com/zephyrproject-rtos/zephyr/blob/master/drivers/counter/Kconfig.maxim_ds3231
