[PATCH 1/1] ARM: exynos_defconfig: Enable options for display panel support

Javier Martinez Canillas [off-list ref] writes:

Many Exynos devices have a display panel, most of them just have
a simple panel while others have more complex configurations that
requires an embedded DisplayPort (eDP) to LVDS display bridge.

This patch enables the following features to support both setups:

- Direct Rendering Manager (DRM)
- DRM bridge registration and lookup framework
- Parade ps8622/ps8625 eDP/LVDS bridge
- NXP ptn3460 eDP/LVDS bridge
- Exynos Fully Interactive Mobile Display controller (FIMD)
- Panel registration and lookup framework
- Simple panels
- Backlight and LCD device support

Some of the options enabled here (e.g: the eDP/LVDS bridges)
are still not merged in mainline so this patch depends on
the following posted patches that were still not merged:

"drm/bridge: Modify drm_bridge core to support driver model" [0]
"drm/bridge: Add i2c based driver for ptn3460 bridge" [1]
"drm/bridge: Add i2c based driver for ps8622/ps8625 bridge" [2]

But I wanted to post anyways to make easier for others to
figure out what are the needed options to have the display
working on their Exynos machines.

Great, thanks for this!  I spent/wasted quite a bit of time trying to
figure out which options I needed to enable to get basic display support
working.

In order to test the display panel on the Peach machines,
the following patches are also needed:

"ARM: dts: Add DT changes for display on peach_pit" [3]
"ARM: dts: Add DT changes for display on peach_pi" [4]

On v3.17-rc1 along with these DT patches abvoe on exynos5800/chromebook2
(peach-pi).

Thanks,

Kevin
