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 an internal DT node to control the PHY
power enable bit.
These patches was tested on Exynos5250.
This PATCH v4 follows:
* PATCH v3, sent on July, 1st 2013
* PATCH v2, sent on June, 28th 2013
* PATCH v1, sent on June, 28th 2013
Changes between v3 and v4:
* Added OF dependancy.
* Removed redundant local variable 'void __iomem *addr'.
* Removed unnecessary dev_set_drvdata().
* Added a patch that remove non-DT support for Exynos
Display Port driver.
* Removed unnecessary 'struct exynos_dp_platdata'.
* Kept supporting the original bindings for DT compatibility.
Changes between v2 and v3:
* Removed redundant spinlock
* Removed 'struct phy' from 'struct exynos_dp_video_phy'
* Updated 'samsung-phy.txt', instead of creating
'samsung,exynos5250-dp-video-phy.txt'.
* Removed unnecessary additional specifier from 'phys'
DT property.
* Added 'phys', 'phy-names' properties to 'exynos_dp.txt' file.
* Added Felipe Balbi's Acked-by.
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].
