Sorry, I can't see anything for Exynos4 there, it's only for exynos5 SoCs.
I think the need for the 'samsung,power-domain' property (I guess that
should be optional) needs to be documented for completeness.

Getting back to the bindings documentation,
Documentation/devicetree/bindings/drm/exynos/ seems not exactly right
place for me, but that's a minor issue. There is also a V4L2 driver
for the HDMI and TV output devices in drivers/media/platform/s5p-tv.
So Documentation/devicetree/bindings/video or
Documentation/devicetree/bindings/media might be a better home for that
bindings documentation. These IPs are not specific to DRM at all.

Thanks,
Sylwester
