| * 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 |
