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 .

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

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.
