[PATCH V4 00/10] drm: exynos: few patches to enhance bridge chip support

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

This series is based on exynos-drm-next branch of Inki Dae's tree at:
git://git.kernel.org/pub/scm/linux/kernel/git/daeinki/drm-exynos.git

I have tested this after adding few DT changes for exynos5250-snow,
exynos5420-peach-pit and exynos5800-peach-pi boards.

This patchset also consolidates various inputs from the drm community
regarding the bridge chaining concept:
(1) [RFC V2 0/3] drm/bridge: panel and chaining
	http://www.spinics.net/lists/linux-samsung-soc/msg30160.html
(2) [RFC V3 0/3] drm/bridge: panel and chaining
	http://www.spinics.net/lists/linux-samsung-soc/msg30507.html

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

The following patches can be divided into 2 groups:
	patches 1 to 4: add drm_panel support to exynos_dp(peach-pi)
	patches 5 to 10: chaining of bridges and drm_panel(snow and peach-pit)
