[PATCH 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.

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
2) Arun's patch for adding peach-pit board dts file at
http://www.mail-archive.com/linux-samsung-soc@vger.kernel.org/msg28846.html.

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 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 Doug Anderson, Tomasz Figa)

'gpx0-7' pin is assigned for standard HPD pin. This is chip specific.
So, there should be "gpx0-7" part on chip specific dts file such as
'exynos5420-pinctrl.dtsi'.

However, some boards use GPIO as HPD pin, instead of 'gpx0-7' pin.
This is board specific. In my opinion, the following would look
better. In this way, this patch is not necessary.

1. case: Standard HPD pin is used. (smdk5420)
arch/arm/boot/dts/exynos5420-pinctrl.dts
	pinctrl@13400000 {
		dp_hpd: dp_hpd {
			samsung,pins = "gpx0-7";
			samsung,pin-function = <3>;
			samsung,pin-pud = <0>;
			samsung,pin-drv = <0>;
		};
arch/arm/boot/dts/exynos5420-smdk5420.dts
	dp-controller@145B0000 {
		pinctrl-names = "default";
		pinctrl-0 = <&dp_hpd>;
		...


2. case: non-standard HPD pin such as GPIO is used. (peach pit)
arch/arm/boot/dts/exynos5420-peach-pit.dts
	pinctrl@13400000 {
		dp_hpd: dp_hpd {
			samsung,pins = "gpx2-6";
			samsung,pin-function = <0>;
			samsung,pin-pud = <3>;
			samsung,pin-drv = <0>;
		};
	dp-controller@145B0000 {
		pinctrl-names = "default";
		pinctrl-0 = <&dp_hpd>;
		...
		samsung,hpd-gpio = <&gpx2 6 0>;

Even though, there is 'dp_hpd' in exynos5420-pinctrl.dts,
'smdk5420' and 'peach pit' can use "gpx0-7" and "gpx2-6",
respectively.

A year ago, Doug Anderson and me agreed that standard HPD pin
part should be included to 'exynos5250-pinctrl.dtsi'.

I wasn't aware of this discussion. It make sense. I will drop this patch.
I need to choose some other name for this pin, say "peach_dp_hpd".
Let me know if any concern.

In my opinion, "dp_hpd_gpio" looks better as below.

arch/arm/boot/dts/exynos5420-peach-pit.dts
	pinctrl@13400000 {
		dp_hpd_gpio: dp_hpd_gpio {
			samsung,pins = "gpx2-6";
			samsung,pin-function = <0>;
			samsung,pin-pud = <3>;
			samsung,pin-drv = <0>;
		};
	dp-controller@145B0000 {
		pinctrl-names = "default";
		pinctrl-0 = <&dp_hpd_gpio>;
		...
		samsung,hpd-gpio = <&gpx2 6 0>;

Re: [PATCH 3/5] ARM: dts: enable dp-controller for exynos5250 based snow board

[Rahul Sharma]

Hi Kukjin,

The only dependency for this patch is new property "samsung,hpd-gpio" which
is acked by Jingoo Han, Maintainer, exynos DP at
http://oascentral.opensubscriber.com/message/dri-devel@lists.freedesktop.org/17150750.html.

All remaining properties are as per existing DT bindings.

@Jingoo, I want to request you to review the dp-controller nodes for
exynos5420 and 5250.

Please consider it for merge.

Regards,
Rahul Sharma.

One more thing. These patches were based against the following patches.

3) Rahul Sharma's patch for hdmi support for exynos5 based dt files.
([PATCH 0/7] ARM: dts: enable hdmi for exynos5 based peach and snow boards)
http://www.spinics.net/lists/linux-samsung-soc/msg29011.html

Please check the dependency.
Anyone does not want to waste the time, due to patch breakage.

Best regards,
Jingoo Han
