The display controller on Tegra can use syncpoints to count VBLANK
events. syncpoints are 32-bit unsigned integers, so well suited as
VBLANK counters.

drm/tegra: Implement more tiling modes2014-08-04T08:07:34ZThierry Redingtreding@nvidia.com2014-06-03T12:48:12Zurn:sha1:c134f019abcfaa1cb6e07f6154e92a4f8ce8ddd8
Tegra124 supports a block-linear mode in addition to the regular pitch
linear and tiled modes. Add support for these by moving the internal
representation into a structure rather than a simple flag.

drm/tegra: Add hardware cursor support2014-06-05T21:14:47ZThierry Redingtreding@nvidia.com2013-12-20T12:58:33Zurn:sha1:e687651bc1ed96b0ad2ee9464f341c53563b5353
Enable hardware cursor support on Tegra124. Earlier generations support
the hardware cursor to some degree as well, but not in a way that can be
generically exposed.

drm/tegra: dc - Rename INVERT_V to V_DIRECTION2014-06-05T21:09:17ZThierry Redingtreding@nvidia.com2014-02-25T11:04:06Zurn:sha1:eba66501ac41b717d60bebc6f9ae0f3195c6c422
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.

drm/tegra: Relocate some output-specific code2013-12-20T14:56:07ZThierry Redingtreding@nvidia.com2013-12-12T10:06:55Zurn:sha1:72d302861530bcdb780ea57ebfc3dff6ec4f802c
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.

drm/tegra: Add Tegra124 DC support2013-12-20T14:56:06ZThierry Redingtreding@nvidia.com2013-12-12T10:03:59Zurn:sha1:8620fc629aeec02ac3b3735703940696386a3039
Tegra124 and later support interlacing, but the driver doesn't support
it yet. Make sure interlacing stays disabled on hardware that supports
it.

drm/tegra: Add DSI support2013-12-20T14:56:04ZThierry Redingtreding@nvidia.com2013-09-03T06:45:46Zurn:sha1:dec727399a4b36bec87b7b4d4c1b20025e69758a
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.

drm/tegra: Support bottom-up buffer objects2013-10-31T08:55:46ZThierry Redingthierry.reding@avionic-design.de2013-10-07T07:47:58Zurn:sha1:db7fbdfd25ee009165b6c3b80a9d1c6d8534ad94
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.
