Does Zephyr support SPMI protocol? If not supported now, will Zephyr support it in the future?

[piterla]

I didn't find SPMI driver at https://github.com/zephyrproject-rtos/zephyr/tree/main/drivers.
The SPMI protocol (System Power Management Interface) is a common interface used in PMIC.

Does SPMI protocol support now?
If Zephyr does not support SPMI protocol now, will Zephyr support it in the future (will support it in what version?)?

Thanks
