the id you want to use actually is a soft-reset index, not a clock-id.
You would need to add a real id, in this case with an sclk_ prefix.

It should probably look more like below, but as suggested by Stephen Boyd
in another thread, we should coordinate with Chris to add more necessary clock
ids in one go:
