Thank you, remaining patches are not posted yet. I'm still working on them and should be posting them this week. They are almost ready and I'm doing some more tests. I have converted the code that was previously added to the exynos-bus driver to a separate interconnect driver as you suggested. In the exynos devfreq only a child platform device is registered for the interconnect driver, which then registers a PM QoS request for its parent device. After rebasing today I noticed something very similar has been recently added in the devfreq subsystem for the imx platforms. Let's discuss further after I actually post the patches. -- Regards, Sylwester
