On all platforms set_clock_selection() writes to a GRF register. This requires certain clocks running and thus should happen before the clocks are disabled.
This has been noticed on RK3576 Sige5, which hangs during system suspend when trying to suspend the second network interface. Note, that suspending the first interface works, because the second device ensures that the necessary clocks for the GRF are enabled.
