DECON-TV IP is responsible for generating video stream which is transferred
to HDMI IP. It is almost fully compatible with DECON IP.

The patch is based on initial work of Hyungwon Hwang.

AFAIK, DECON TV for Exynos5433 SoC has four hardware overlays so I guess 
you used ctx->first_win to initialize four planes in case of IFTYPE_HDMI.

However, with IFTYPE_HDMI ctx->first_win has 1, as a result, 
ctx->planes[] will have 0, 2nd, 3rd and 4th planes and this means we 
should use 0, 2nd ~ 4th hardware overlay excepting 1st overlay. Is this 
your intention?
Shouldn't ctx->planes[] have 1st, 2nd ,3rd and 4th planes so that we can 
use 1st ~ 4th hardware overlay for DECON TV?

DECON TV for Exynos5433 SoC can use only 1st ~ 4th hardware overlays.

And other thing, it may be trivial but I think it'd be better to use 
'ovl' instead of 'tmp.

Thanks,

DECON-TV has hardware window 0 with very limited functionality,
it is just background color, no scanout buffers. So it cannot be used
as drm plane. ctx->first_win contains value of the 1st valid window.
There is a question how to map windows to planes. I have chosen
the simplest solution - n'th hw window is mapped to n'th plane and have
zpos==n. The only problem is with function exynos_plane_get_type,
which returns DRM_PLANE_TYPE_PRIMARY only if their 1st argument is equal 0,
ie it assumes default window is always 0.
As an simple workaround I used 'tmp' variable which maps 1st window to 0.
This way exynos_plane_get_type returns expected value for all windows.
I plan replace this workaround with something nicer, but as it would involve
changes in other drivers I left this as TODO for later.
Regarding ctx->planes[], it is static array so it will have always one entry
invalid in case of TV, with this approach it will be th 0th entry, but with a gain
of consistency in windows/zpos/planes numbering.
If you prefer different approach please let me know.

What concerns me was each plane could be mapped to wrong hardware
overlay. However, this was my miss leading. I missed the variable
'tmp' is used only to get plane type.

Ok, let's have more cleanup later.
