+ * This file contains clockdomains and clockdomain wakeup/sleep

+ *
+ * A useful validation rule for struct clockdomain: Any clockdomain
+ * 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).
+ *
+ * The overly-specific dep_bit names are due to a bit name collision
+ * with CM_FCLKEN_{DSP,IVA2}.  The DSP/IVA2 PM_WKDEP and CM_SLEEPDEP shift
+ * value are the same for all powerdomains: 2
+ *
+ * XXX should dep_bit be a mask, so we can test to see if it is 0 as a
+ * sanity check?
+ * XXX encode hardware fixed wakeup dependencies -- esp. for 3430 CORE
