V_DIRECTION is the name of the field in the documentation, so use that
for consistency. Also add the H_DIRECTION field for completeness.

Add support for eDP functionality found on Tegra124 and later SoCs. Only
fast link training is currently supported.

Some of the code in the CRTC's mode setting code is specific to the RGB
output or needs to be called slightly differently depending on the type
of output. Push that code down into the output drivers.

Tegra124 and later support interlacing, but the driver doesn't support
it yet. Make sure interlacing stays disabled on hardware that supports
it.

This commit adds support for both DSI outputs found on Tegra. Only very
minimal functionality is implemented, so advanced features like ganged
mode won't work.

Due to the lack of other test hardware, some sections of the driver are
hardcoded to work with Dalmore.

The gr3d engine renders images bottom-up. Allow buffers that are used
for 3D content to be marked as such and implement support in the display
controller to present them properly.

The gr2d and gr3d engines work more efficiently on buffers with a tiled
memory layout. Allow created buffers to be marked as tiled so that the
display controller can scan them out properly.

All the necessary support bits like .mode_set_base() and VBLANK are now
available, so page-flipping case easily be implemented on top.

Add support for the B and C planes which support RGB and YUV pixel
formats and can be used as overlays or hardware cursor. Currently 32-bit
XRGB as well as UYVY, YUV420 and YUV422 pixel formats are advertised.
Other formats should be easy to add but these are the most common ones
and should cover the majority of use-cases.

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.
