KMS driver for TI LCD controller

* 'tilcdc-next' of git://people.freedesktop.org/~robclark/linux:
  drm/tilcdc: add support for LCD panels (v5)
  drm/tilcdc: add encoder slave (v2)
  drm/i2c: nxp-tda998x (v3)
  drm/tilcdc: add TI LCD Controller DRM driver (v4)
  drm/nouveau: use i2c encoder helper wrappers
  drm: i2c encoder helper wrappers
  drm/cma: add debugfs helpers
  drm: small fix in drm_send_vblank_event()
  drm: Don't set the plane->fb to NULL on successfull set_plane
  drm/cma-helper: fixup compilation

A simple DRM/KMS driver for the TI LCD Controller found in various
smaller TI parts (AM33xx, OMAPL138, etc).  This driver uses the
CMA helpers.  Currently only the TFP410 DVI encoder is supported
(tested with beaglebone + DVI cape).  There are also various LCD
displays, for which support can be added (as I get hw to test on),
and an external i2c HDMI encoder found on some boards.

The display controller supports a single CRTC.  And the encoder+
connector are split out into sub-devices.  Depending on which LCD
or external encoder is actually present, the appropriate output
module(s) will be loaded.

v1: original
v2: fix fb refcnting and few other cleanups
v3: get +/- vsync/hsync from timings rather than panel-info, add
    option DT max-bandwidth field so driver doesn't attempt to
    pick a display mode with too high memory bandwidth, and other
    small cleanups
v4: remove some unneeded stuff from panel-info struct, properly
    set high bits for hfp/hsw/hbp for rev 2, add DT bindings docs

Now that the omapdss interface has been reworked so that omapdrm can use
dispc directly, we have been able to fix the remaining functional kms
issues with omapdrm.  And in the mean time the PM sequencing and many
other of that open issues have been solved.  So I think it makes sense
to finally move omapdrm out of staging.

Move this out of nouveau directory.  As we start to add more encoder
slaves used by other drivers, it makes sense to put the Kconfig bits in
one place.

KMS support is out and stable for a couple of years now and
the userspace code has deprecated or abandoned the old UMS interface.

So make the KMS interface the default and deprecate the UMS interface
in the kernel as well.

v2: rebased on alex/drm-next-3.9-wip

This commit adds a KMS driver for the Tegra20 SoC. This includes basic
support for host1x and the two display controllers found on the Tegra20
SoC. Each display controller can drive a separate RGB/LVDS output.

The SH Mobile LCD controller (LCDC) DRM driver supports the main
graphics plane in RGB and YUV formats, as well as the overlay planes (in
alpha-blending mode only).

Only flat panel outputs using the parallel interface are supported.
Support for SYS panels, HDMI and DSI is currently not implemented.

[Make DRM_KMS_CMA_HELPER a boolean Kconfig option]
Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com>

Many embedded drm devices do not have a IOMMU and no dedicated
memory for graphics. These devices use CMA (Contiguous Memory
Allocator) backed graphics memory. This patch provides helper
functions to be able to share the code. The code technically does
not depend on CMA as the backend allocator, the name has been chosen
because CMA makes for a nice, short but still descriptive function
prefix.
