Right now hdmiphy operations and configs are kept inside hdmi driver. hdmiphy related code is tightly coupled with hdmi ip driver. Physicaly they are different devices and should be instantiated independently.
In terms of versions/mapping/configurations Hdmi and hdmiphy are independent of each other. It seems logical to isolate them and maintained independently.
This implementation is tested for: 1) Resolutions supported by exynos4 and 5 hdmi. 2) Runtime PM and S2R scenarions for exynos5.
