This patchset series adds HDMI video support to the Allwinner
sun8i SoCs which include the display engine 2 (DE2).
The driver contains the code for the A83T and H3 SoCs, and
some H3 boards, but it could be used/extended for other SoCs
(A64, H2, H5) and boards (Banana PIs, Orange PIs).

	- more explanations about the DE2 in the DT documentation
	- separate patches for DT documentation (Rob Herring)
	- show all properties in DT examples (Rob Herring)
	- use drm_of_component_probe()
	- use the index of the DE 'ports' in the DT as
	  the DE mixer number (no alias needed anymore)
	- change some 'lcd' to 'tcon' in the DT
	- add HDMI module parameter for DVI mode when screen overscan
	- fall back to some CEA modes in case of EDID read failure
	- fix some settings (interlace) and simplify code
	- fix bug in start of A83T HDMI
	- fix lack of CLK_PLL_DE definition in the DT include
	  (Icenowy Zheng)
	- remove audio support (other patchset to come)
	- use DRM modeset data for HDMI configuration
		(thanks to Jernej Å krabec)
	- more meaningfull register names
	- use a mutex for DE I/O protection
	- merge DE and plane into one file
	- don't activate the video hardware when video not started
		(Maxime Ripard)
	- remove 'type = "video" in DT graph ports
		(Rob Herring)
	- change the I/O accesses by #define instead of struct
		(Maxime Ripard, André Przywara)
	- remove pm functions (Maxime Ripard)
	- set the pll-de/de clocks in the DT (Maxime Ripard)
	- use platform_get_irq instead of irq_of_parse_and_map
		(Maxime Ripard)
	- rename sunxi to sun8i (Maxime Ripard)
	- fix coding style errors (Maxime Ripard)
	- subclass the drm structure in private data (Daniel Vetter)
	- move drm_dev_register at end of init (Daniel Vetter)
	- add overlay plane
	- add audio support
	- add support for the A83T
	- add back the HDMI driver
	- many bug fixes
	- drivers/clk/sunxi/Makefile was missing (Emil Velikov)
	- add the hardware cursor
	- simplify and fix the DE2 init sequences
	- generation for all SUNXI SoCs (Andre Przywara)
	- remove the HDMI driver
	- remarks from Chen-Yu Tsai and Russell King
	- DT documentation added
