I think the specifier is only the part after the phandle, so this should probably be "... compatible PHYs the single cell specifier ..." or something equivalent.

I think you need to specify the literal values here as well, since the binding must be fully self-contained. That is you can't rely on the DT binding to be bundled with the exynos-simple-phy.h header.

Perhaps this should be named phy-exynos-simple for consistency? Also it may be a good idea to sort this alphabetically to reduce the potential for conflicts.

Why does this need of_match_ptr()?

If at all this should be dev_dbg(). But in general the driver core will already complain if the driver fails to probe, so there's in general no need to mention when it probes successfully.

s/simeple phys/simple PHYs/
Although on second thought that comment probably shouldn't be there in the first place.

This doesn't belong in this header. The value should never be used by a DT source file, should it?

Perhaps these should be namespaced somehow to avoid potential conflicts with other PHY providers?

I'm not sure that this belongs here either. It's not a value that will ever appear in a DT source file.
