This series is based on exynos-drm-next branch of Inki Dae's tree at: git://git.kernel.org/pub/scm/linux/kernel/git/daeinki/drm-exynos.git
I have tested this after adding few DT changes for exynos5250-snow, exynos5420-peach-pit and exynos5800-peach-pi boards.
I'm trying to test this with a modified exynos5250-spring DT based off kgene's for-next branch due to DT, and I run into the following:
CC drivers/gpu/drm/bridge/ptn3460.o drivers/gpu/drm/bridge/ptn3460.c: In function ‘ptn3460_post_encoder_init’: drivers/gpu/drm/bridge/ptn3460.c:275:2: error: implicit declaration of function ‘drm_connector_register’ [-Werror=implicit-function-declaration] drm_connector_register(&ptn_bridge->connector); ^
Hope this might help: http://www.spinics.net/lists/dri-devel/msg60578.html
That fixed my build, thanks.
Unfortunately the most I got on Spring with attached DT was a blank screen with a white horizontal line in the middle.
Do I need to specify a specific panel model for Spring?
For testing I re-applied your iommu patches (which btw fail now for 5420 due to disp_pd) but didn't know what to do about your panel-lvds regulator patch now that it's gone.
If I don't apply this series, then commenting out the dp-controller node gets me a working display with simplefb as before.

You can't do this. "simple-panel" isn't a valid panel model. It should probably be removed from the platform_of_match table in the driver.
