[PATCH v2 0/5] ARM: dts: enable display for peach-pit and snow boards

[PATCH v2 0/5] ARM: dts: enable display for peach-pit and snow boards

[Rahul Sharma]

From: Rahul Sharma <Rahul.Sharma@samsung.com>

Add nodes for fimd and dp controller for exynos5250 based snow
and exynos5420 based peach-pit board.

This series is based on Kukjin Kims, for-next branch.

V2:
1) Rebase on Peach-pit dependent patches.

It is dependent on
1) Andrew Bresticker's patch for hpd gpio addition, avilable at
http://www.spinics.net/lists/linux-samsung-soc/msg28827.html [Patch is 'ACK'ed.]
2) Arun's patch for adding peach-pit board dts file at
http://www.spinics.net/lists/linux-samsung-soc/msg30103.html. [Patch is 'ACK'ed.]

Rahul Sharma (5):
  ARM: dts: move dp hpd line to the board file for exynos5420
  ARM: dts: enable fimd for exynos5250 based snow board
  ARM: dts: enable dp-controller for exynos5250 based snow board
  ARM: dts: enable fimd for exynos5420 based peach-pit board
  ARM: dts: enable dp-controller for exynos5420 based peach-pit board

[PATCH v2 1/5] ARM: dts: move dp hpd line to the board file for exynos5420

[Rahul Sharma]

From: Rahul Sharma <Rahul.Sharma@samsung.com>

Display controller HPD Gpio line is board specific. This patch
is moving the pinctrl for hpd gpio line to the respective board
file.

(+cc Sachin Kamat, Tomasz Figa)

For readability, how about moving 'status' to the last entry of
the node? The same comment applies to other patches, too.

I just followed the nodes in rest of the file for peach and snow. This
looks consistent to me. But let me know if you want me to change
this.

Either at the top or bottom is fine rather than somewhere in between.
However no need to re-spin the patch just for this change.

For readability, please insert one line as below.

The same comment applies to the 5th patch.
