I hope to add Exynos5 SYSMMU patches to the next iteration of my patchset,
but I doubt it will get into v3.19-rc1.

We have observed similar issues with Exynos4 based boards, when LCD0 power
domain was turned off and only TV power domain has been powered on. Please
check the power domain configuration. Maybe in case of Exynos5 the same
issue
is caused by the interaction between DISP1 and GSCL domains.
