Subject: [PATCH V7 0/3] Generic PHY driver for the Exynos SoC DP PHY

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 v7 follows:
 * PATCH v6, sent on July, 9th 2013
 * PATCH v5, sent on July, 8th 2013
 * PATCH v4, sent on July, 2nd 2013
 * PATCH v3, sent on July, 1st 2013
 * PATCH v2, sent on June, 28th 2013
 * PATCH v1, sent on June, 28th 2013

Changes from v6:
  * Re-based on git://git.kernel.org/pub/scm/linux/kernel/git/kishon/linux-phy.git

Changes from v5:
  * Re-based on git://gitorious.org/linuxphy/linuxphy.git

Changes from v4:
  * Marked original bindings as deprecated in 'exynos_dp.txt'
  * Fixed typo of commit message.
  * Added Tomasz Figa's Reviewed-by.

Changes from v3:
  * 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 from v2:
  * 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 from v1:
  * 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].
