Looking through the branch contents, I noticed that the examples in the
bindings contain mandatory properties that are not documented.
I have merged your branch into next/cleanup3 of the arm-soc tree,
but I also applied a patch on top to document the missing strings
and properties. It is currently the top commit on the branch, so
if anyone spots a mistake, we can probably rectify it.
Please be more careful with binding documentation in the future.
Was this actually reviewed on the devicetree-discuss mailing list?

Subject: [PATCH] devicetree: fix newly added exynos sata bindings
Commit ba0d7ed391b7b "ARM: dts: enable ahci sata and sata phy for
exynos5250" added a new binding document for the sata phy device,
and changed the sata controller binding. However, in both cases
significant aspects of the binding remained undocumented.
This attempts to reconstruct the actual binding from the usage.
