Instead of having separate implementations for all of them, where all will eventually lack something or the other, lets try to implement a common solution for everyone. This takes care of setting regulators, bw, required opps, etc for all device types. Dmitry, please go ahead and try this series. This is based of opp tree's linux-next branch. Sibi, since you added dev_pm_opp_set_bw() earlier, it would be good if you can give this a try. In case this breaks anything for you. I have already tested this on hikey board for CPU devices. To get this tested better and as early as possible, I have pushed it here: git://git.kernel.org/pub/scm/linux/kernel/git/vireshk/pm.git opp/linux-next This will be part of linux-next tomorrow. Note, all the patches need to go through OPP tree here.
