Is there a reset control API in Zephyr?

[billy-tsai]

Hi,
I want to know that if the zephyr has a common API like Linux: reset to control the reset?

[dlktdr]

It has a sys_reboot function,

sys_reboot(SYS_REBOOT_COLD);

You will need the CONFIG_REBOOT=y KConfig option set to be able to use it. https://docs.zephyrproject.org/latest/reference/kconfig/CONFIG_REBOOT.html

Hi @dlktdr,
Thanks for your reply.
But my question is common API that can be used in the driver init function, like reset_control_deassert(...) can deassert the reset of the device, not the function used to reboot the system.

I don't think there is a unified API for reset pins.

The current (v2.7) standard way is to use GPIO,
But pinctrl discussion is on going (#35077)
