This patch fixes DRM_EXYNOS7DECON to DRM_EXYNOS7_DECON.

Signed-off-by: Inki Dae <inki.dae@samsung.com>

This patch 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

DECON(Display and Enhancement Controller) is the new IP
in exynos7 SOC for generating video signals using pixel data.

DECON driver can be used to drive 2 different interfaces on Exynos7:
DECON-INT(video controller) and DECON-EXT(Mixer for HDMI)

The existing FIMD driver code was used as a template to create
DECON driver. Only DECON-INT is supported as of now, and
DECON-EXT support will be added later.

The current version of the driver supports video mode displays.

Changelog v2:
- Change config name, DRM_EXYNOS_DECON to DRM_EXYNOS7_DECON.

The exynos drm driver has DRIVER_PRIME capability, then it's reasonable
to support dmabuf as default. Remove DRM_EXYNOS_DMABUF config, it will
prevent that user selects the option unnecessarily.

If system provides IOMMU feature, Exynos DRM should use it by default,
because the Exynos DRM subdrivers don't work correctly when Exynos IOMMU
driver has been enabled and no IOMMU support has been compiled into Exynos
DRM driver.

commit 765d5b9c2b72f5b9 ("fbdev: fbcon: select VT_HW_CONSOLE_BINDING")
made FRAMEBUFFER_CONSOLE always select VT_HW_CONSOLE_BINDING, but forgot
to remove

	select VT_HW_CONSOLE_BINDING if FRAMEBUFFER_CONSOLE

from the individual drivers' sections that already did this before.

Remove it, also from new drivers.

drm/panel: Changes for v3.17-rc1

Panels can now be more finely controlled via .prepare() and .unprepare()
callbacks in addition to .enable() and .disable(). New kerneldoc details
what they are supposed to do and when they should be called.

The simple panel driver gained support for a couple of new panels and it
is now possible to specify additional delays during power up and power
down sequences if panels require it.

DSI devices can now advertise that they support non-continuous clock
mode which will allow DSI host controllers to disable the high speed
clock after transmissions to save power.

To support MIPI command mode based I80 interface panel,
FIMD should do followings:
- Sets LCD I80 interface timings configuration.
- Uses "lcd_sys" as an IRQ resource and sets relevant IRQ configuration.
- Sets LCD block configuration for I80 interface.
- Sets ideal(pixel) clock is 2 times faster than the original one
  to generate frame done IRQ prior to the next TE signal.
- Implements trigger feature that transfers image data if there is page
  flip request, and implements TE handler to call trigger function.
