How to get multiple devices with unique addresses on the Nordic 5340 microprocessor to work on i2c bus?

I'm trying to get a gas gauge and charger IC to work on the i2c bus. Both have different addresses. I'm able to read from the gas gauge address but not the IC. Are there specific configurations that needs to be added on the IC node? How do you set up write/read for the charger IC?

Hi!

Thingy:53 have several different sensors, with different I2C addresses, connected to the same I2C bus. You can see how the configuration is done there as a reference.

Thank you. What about how to get it to work with a charger IC? An analog device (adp5062)?

I don't see any ready-made drivers for adp5062 in Zephyr. There is however one for adp5360, likely it can be used as a reference to create one for adp5062. https://github.com/zephyrproject-rtos/zephyr/blob/main/drivers/regulator/regulator_adp5360.c .
