 *
 * This file contains clockdomains and clockdomain wakeup/sleep
 * dependencies for the OMAP2/3 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).
 *
 * 24xx does not support programmable sleep dependencies (SLEEPDEP)
 *
 * 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
