It is based on v3.17-rc3. Excellent! Thank you. The only thing missing now is the CPUidle support for 5800, and all that's needed for that is the compatible string patch[1] which Daniel has queued up. With that patch, display + CPUidle + CPUfreq are working pretty well on my exynos5800/chromebook2 with the big.LITTLE switcher disabled. If I turn on the switcher, it boots OK, but as soon as I try to run powertop (upstream v2.6.1) it gets stuck. Have you tried this branch with the switcher enabled? Thanks again for your work on this, we're getting close! Kevin [1] http://lists.infradead.org/pipermail/linux-arm-kernel/2014-August/279028.html
