a134789a67 gpu: host1x: Add Tegra210 support 
The host1x unit found in Tegra210 SoCs is very similar to the unit in
Tegra124, but it has 2 additional channels for a total of 14 channels.

e6fff4aaf9 gpu: host1x: Add Tegra124 support 
Tegra124 has 192 syncpoints whereas its predecessors had 32 syncpoints.
This required changes to the hardware register layout.

776dc38403 drm/tegra: Move subdevice infrastructure to host1x 
The Tegra DRM driver currently uses some infrastructure to defer the DRM
core initialization until all required devices have registered. The same
infrastructure can potentially be used by any other driver that requires
more than a single sub-device of the host1x module.

Make the infrastructure more generic and keep only the DRM specific code
in the DRM part of the driver. Eventually this will make it easy to move
the DRM driver part back to the DRM subsystem.

de2ba664c3 gpu: host1x: drm: Add memory manager and fb 
This patch introduces a memory manager for tegra drm and moves
existing parts to use it. As cma framebuffer helpers can no more
be used, this patch adds also a separate framebuffer driver for
tegra.
