Later we need to add PSR relevant codes instead.
I'm afraid this patch doesn't fix the regression I'm seeing on my Exynos5250 Chromebook. I found out that using the 4.6 device tree allows the display to function correctly (at least for a while), just enough to see it dying before reaching userspace (and it scrolls up way to quickly for me to read it). Adding printk_delay results in a hanging system. Can someone with a servo-board investigate this? I'll try to bisect it further, but an actual backtrace would help. Thanks, M. -- Fast, cheap, reliable. Pick two.
