Maybe this should be reworded to something like the following?

<--- cut
The SCP_ADSP clock controller has a power domain dependency that was not
described properly. Add it to the binding.

This was discovered when I was reworking the clock drivers. The clocks
in this controller were being turned off by the clock core, which would
result in the system locking up. MediaTek said this was due to the power
domain.
