[PATCH V7 00/12] drm/exynos: few patches to enhance bridge chip support

[Ajay Kumar <ajaykumar.rs@samsung.com>]

This series is based on master branch of Linus tree at:
git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git

I have tested this after adding few DT changes for exynos5250-snow and
exynos5420-peach-pit boards.

The V4 series of this particular patchset was also tested by:
Rahul Sharma <rahul.sharma@samsung.com>
Javier Martinez Canillas <javier@dowhile0.org>

Changes since V2:
	-- Address comments from Jingoo Han for ps8622 driver
	-- Address comments from Daniel, Rob and Thierry regarding
	   bridge chaining
	-- Address comments from Thierry regarding the names for
	   new drm_panel functions

Changes since V3:
	-- Remove hotplug based initialization of exynos_dp
	-- Make exynos_dp work directly with drm_panel, remove
	   dependency on panel_binder
	-- Minor cleanups in panel_binder and panel_lvds driver

Changes since V4:
	-- Use gpiod interface for panel-lvds and ps8622 drivers.
	-- Address comments from Javier.
	-- Fix compilation issues when PANEL_BINDER is selected as module.
	-- Split Documentation patches from driver patches.
	-- Rebase on top of the tree.

Changes since V5:
	-- Modify bridge drivers to support driver model.
	-- Drop the concept of bridge chain(sincle there are no 2 real bridges)
	   Hence drop bridge-panel_binder layer.
	-- Drop panel-lvds driver and accomodate the required changes in
	   panel-simple driver.
	-- Use gpiod interface in ptn3460 driver.
	-- Address all comments by Thierry Reding for V5 series.
	-- Address comments from Sean Paul for exynos_dp_commit issue.

Changes since V6:
	-- Panel patches were seperated and they are merged already.
	-- Fix few issues with ptn3460, before modifying the bridge core.
	-- Modify drm_bridge as per Thierry's comments for V6 series.
	-- Add drm_bridge changes minimally without breaking existing code.
	-- Add new features for ptn3460, step-by-step.
	-- Address comments from Thierry and Andreas for ptn3460 and ps8622.
	-- Split documentation patches from driver patches.

"[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

What's the best way to fix the above ambiguity?
