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] Tested-by: Kevin Hilman <khilman@linaro.org> On v3.17-rc1 along with these DT patches abvoe on exynos5800/chromebook2 (peach-pi).

I already sent this a week back.Find it here: http://www.spinics.net/lists/dri-devel/msg66740.html Inki Dae, In this patchset, patch "[PATCH V7 5/12] drm/exynos: dp: support drm_bridge" introduces following Kconfig error: drivers/video/fbdev/Kconfig:5:error: recursive dependency detected! drivers/video/fbdev/Kconfig:5: symbol FB is selected by DRM_KMS_FB_HELPER drivers/gpu/drm/Kconfig:39: symbol DRM_KMS_FB_HELPER depends on DRM_KMS_HELPER drivers/gpu/drm/Kconfig:33: symbol DRM_KMS_HELPER is selected by DRM_BRIDGE drivers/gpu/drm/bridge/Kconfig:1: symbol DRM_BRIDGE is selected by DRM_EXYNOS_DP drivers/gpu/drm/exynos/Kconfig:53: symbol DRM_EXYNOS_DP depends on DRM_EXYNOS_FIMD drivers/gpu/drm/exynos/Kconfig:28: symbol DRM_EXYNOS_FIMD depends on FB_S3C drivers/video/fbdev/Kconfig:2038: symbol FB_S3C depends on FB How to fix this?

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 Signed-off-by: Javier Martinez Canillas <javier.martinez@collabora.co.uk> --- 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. 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] Best regards, Javier [0]: http://patchwork.ozlabs.org/patch/373792/ [1]: http://patchwork.ozlabs.org/patch/373793/ [2]: http://patchwork.ozlabs.org/patch/373794/ [3]: http://www.spinics.net/lists/arm-kernel/msg350568.html [4]: http://www.spinics.net/lists/arm-kernel/msg350569.html arch/arm/configs/exynos_defconfig | 14 ++++++++++++++ 1 file changed, 14 insertions(+)
