* This is not an exhaustive listing of powerdomains on the chips; only

- * A useful validation rule for struct powerdomain:
- * Any powerdomain referenced by a wkdep_srcs or sleepdep_srcs array
- * must have a dep_bit assigned. So wkdep_srcs/sleepdep_srcs are really
- * just software-controllable dependencies. Non-software-controllable
- * dependencies do exist, but they are not encoded below (yet).
- *
- * 24xx does not support programmable sleep dependencies (SLEEPDEP)
