[GIT PULL] VC4 3D support

[Eric Anholt]

Hi Dave,

Since you asked for early pull requests, here's what I've got queued up.
I may want to add some more after this if I can, but this will let us
ship 3D support on 4.5 kernels.  It's also what I'm pushing to the
Raspberry Pi Foundation kernel for their update to 4.2.

The following changes since commit 8005c49d9aea74d382f474ce11afbbc7d7130bec:

  Linux 4.4-rc1 (2015-11-15 17:00:27 -0800)

are available in the git repository at:

  drm/vc4: Add support for more a few more RGB display plane formats. (2015-12-11 16:27:47 -0800)

----------------------------------------------------------------
This pull request brings in 3D acceleration support for the VC4 GPU.
While there is still performance work to be done (particularly
surrounding RCL generation), the CL submit ABI should be settled and
done now.
