This is a question I can't answer definitively as I don't know what
happens during a suspend on your hardware, and thus which registers
are lost / reset by the time the system resumes. So I can only give
the obvious guidance.

If the settings in the delay registers are lost over a suspend/resume
then they need to be re-initialised after resume.
