[PATCH V3 0/7] Update Arndale board support

[Tushar Behera]

Arndale board support has been updated using pin-control and
common clock framework.

The patchset is based on Kukjin's for-next.
commit d58f6a153f40 ("Merge branch 'next/clk-exynos-2' into for-next")

It depends on following patchset.

[PATCH 0/2] ARM: dts: Add default pin states for client nodes on Exynos4/5 platforms
http://comments.gmane.org/gmane.linux.kernel.samsung-soc/16559

Following 2 patches have been newly added in this patchset because
of changes during 3.9 merge window.
1/7: ARM: dts: Add pin-control related changes for Arndale board
2/7: ARM: dts: Add disable-wp for card slot on exynos5250-arndale

Amit Daniel Kachhap (1):
  ARM: dts: Add PMIC node entry for Arndale board

Sachin Kamat (4):
  ARM: dts: Add disable-wp for card slot on exynos5250-arndale
  ARM: dts: Add vmmc regulator support for Arndale board
  ARM: dts: Add MFC codec support for Arndale board
  ARM: dts: Add HDMI HPD and regulator node for Arndale board

Tushar Behera (2):
  ARM: dts: Add pin-control related changes for Arndale board

[PATCH V3 4/7] ARM: dts: Add PMIC node entry for Arndale board

[Tushar Behera]

From: Amit Daniel Kachhap <amit.daniel@samsung.com>

Added S5M8767 PMIC DT nodes for Arndale board. Only the used
LDO's/BUCK are defined here. Also the nodes describe the default/reset
state LDO's and no power mangement tuning is implemented. The usage
desription can be found in s5m8767 device tree binding documentation.
