This patch series adds a simple driver for the Samsung Exynos SoC
series DP transmitter PHY, using the generic PHY framework [1].
Previously the DP PHY used a platform callback or internal DT node
to control the PHY power enable bit.
The platform callback and internal DT node can be dropped and this
driver does not need any calls back to the platform code.
These patches was tested on Exynos5250.
This PATCH v2 follows:
* PATCH v1, sent on June, 28th 2013
Changes between v1 and v2:
* Replaced exynos_dp_video_phy_xlate() with of_phy_simple_xlate(),
as Kishon Vijay Abraham I guided.
* Set the value of phy-cells as 0, because the phy_provider implements
only one PHY.
* Removed unnecessary header include.
* Added '#ifdef CONFIG_OF' and of_match_ptr macro.
This series depends on the generic PHY framework [1]. These patches
refer to Sylwester Nawrocki's patches about Exynos MIPI [2].
