drm/tegra: Changes for v3.10-rc1
The bulk of this pull-request is the host1x series that has been in the
works for a few months. The current implementation looks good and has
been tested by several independent parties. So far no issues have been
found. To be on the safe side, the new Tegra-specific DRM IOCTLs depend
on staging in order to give some amount of flexibility to change them
just in case. The plan is to remove that dependency once more userspace
exists to verify the adequacy of the IOCTLs.
Currently only the 2D engine is supported, but patches are in the works
to enable 3D support on top of this framework as well. Various bits of
open-source userspace exist to test the 2D and 3D support[0]. This is
still a bit immature but it allows to verify that the kernel interfaces
work properly.
To round things off there are two smaller cleanup patches, one of them
adding a new pixel format and the other removing a redundent Kconfig
dependency.
