| 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 | |
