Ulf Hansson 9ec87c5957 OPP: Fix support for required OPPs for multiple PM domains ... It has turned out that having _set_required_opps() to recursively call dev_pm_opp_set_opp() to set the required OPPs, doesn't really work as well as we expected. More precisely, at each recursive call to dev_pm_opp_set_opp() we are changing an OPP for a required_dev that belongs to a required-OPP table. The problem with this, is that we may have several devices sharing the same required-OPP table, which leads to an incorrect behaviour in regards to aggregating the per device votes. To fix the problem for a required-OPP table belonging to a PM domain, which is the only existing usecase for now, let's simply replace the call to dev_pm_opp_set_opp() in _set_required_opps() by a call to _set_opp_level(). Moving forward we may potentially need to add support for other types of required-OPP tables. In this case, the aggregation needs to be thought of.
