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
