   9  * This file contains clockdomains and clockdomain wakeup/sleep
  10  * dependencies for the OMAP2/3 chips.  Some notes:
  11  *
  12  * A useful validation rule for struct clockdomain: Any clockdomain
  13  * referenced by a wkdep_srcs or sleepdep_srcs array must have a
  14  * dep_bit assigned.  So wkdep_srcs/sleepdep_srcs are really just
  15  * software-controllable dependencies.  Non-software-controllable
  16  * dependencies do exist, but they are not encoded below (yet).
  17  *
  18  * 24xx does not support programmable sleep dependencies (SLEEPDEP)
  19  *
  20  * The overly-specific dep_bit names are due to a bit name collision
  21  * with CM_FCLKEN_{DSP,IVA2}.  The DSP/IVA2 PM_WKDEP and CM_SLEEPDEP shift
  22  * value are the same for all powerdomains: 2
  23  *
  24  * XXX should dep_bit be a mask, so we can test to see if it is 0 as a
  25  * sanity check?
  26  * XXX encode hardware fixed wakeup dependencies -- esp. for 3430 CORE
  27  */
