Hi Cristian,

I've tested this series on sa8797p hardware and did not experience any issues

with registering functions during probe. Can you provide me with the pin

topology of your emulated setup? I have a hunch that the topology may

contain a function with 0 groups which is why -EINVAL is being returned.

The previous pinctrl_scmi_get_function_groups callback considered a function

with no groups invalid.

Best,
Alex
