At Tony's request, remove the omap_chip bitmasks from the clockdomain and clockdomain dependency definitions. Instead, initialize clockdomains based on one or more lists that are applicable to a particular SoC family, variant, and silicon revision. Tony Lindgren <tony@atomide.com> found a bug in a previous version of this patch - thanks Tony. Signed-off-by: Paul Walmsley <paul@pwsan.com> Cc: Tony Lindgren <tony@atomide.com>

|
* 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
|
