  * This file contains clockdomains and clockdomain wakeup/sleep
  * dependencies for the OMAP3xxx chips.  Some notes:
  *
  * 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
