I not have platforms that has ACPI support. Cristian, Sudeep do you have
plans?

I could add depends on OF in V4, since current patch version is
https://lore.kernel.org/all/20240121-pinctrl-scmi-v3-4-8d94ba79dca8@xxxxxxx/

or I could use a follow up patch after V4 patch 1-4 applied.

Would you ACK the current V3 patch or wait I add OF dependency?

Thanks,
Peng.
