pll->pll transitions will *not* work correctly at the moment, pending
me tricking the binary driver into doing one and seeing how to correctly

i915: add dmabuf/prime buffer sharing support.
This adds handle->fd and fd->handle support to i915, this is to allow
for offloading of rendering in one direction and outputs in the other.
v2 from Daniel Vetter:
- fixup conflicts with the prepare/finish gtt prep work.
- implement ppgtt binding support.
Note that we have squat i-g-t testcoverage for any of the lifetime and
access rules dma_buf/prime support brings along. And there are quite a
few intricate situations here.
Also note that the integration with the existing code is a bit
hackish, especially around get_gtt_pages and put_gtt_pages. It imo
would be easier with the prep code from Chris Wilson's unbound series,
but that is for 3.6.
Also note that I didn't bother to put the new prepare/finish gtt hooks
to good use by moving the dma_buf_map/unmap_attachment calls in there
(like we've originally planned for).
Last but not least this patch is only compile-tested, but I've changed
very little compared to Dave Airlie's version. So there's a decent
chance v2 on drm-next works as well as v1 on 3.4-rc.
v3: Right when I've hit sent I've noticed that I've screwed up one
obj->sg_list (for dmar support) and obj->sg_table (for prime support)
disdinction. We should be able to merge these 2 paths, but that's
material for another patch.

drm/i915: fixup infoframe support for sdvo
At least the worst offenders:
- SDVO specifies that the encoder should compute the ecc. Testing also
shows that we must not send the ecc field, so copy the dip_infoframe
struct to a temporay place and avoid the ecc field. This way the avi
infoframe is exactly 17 bytes long, which agrees with what the spec
mandates as a minimal storage capacity (with the ecc field it would
be 18 bytes).
- Only 17 when sending the avi infoframe. The SDVO spec explicitly
says that sending more data than what the device announces results
in undefined behaviour.
- Add __attribute__((packed)) to the avi and spd infoframes, for
otherwise they're wrongly aligned. Noticed because the avi infoframe
ended up being 18 bytes large instead of 17. We haven't noticed this
yet because we don't use the uint16_t fields yet (which are the only
ones that would be wrongly aligned).

- in assert_fdi_tx_pll_enabled (we have the combination of iCLKIP and

use one clock, and pipe to use another, everything hangs. Right now,
we configure all of them in one place only; but yes, when DP code
lands it will get more funky.

drm/prime: expose capability flags for userspace.
This lets the kernel tell userspace if the device supports prime
import/export.
This is useful for -modesetting at least, but would be nice for other
drivers.

drm/exynos: add G2D driver
Changelog v3:
- use __u64 instead of pointer in ioctl struct.
The G2D is a 2D graphic accelerator that supports Bit Block Transfer.
This G2D driver is exynos drm specific and supports only G2D(version
4.1) of later Exynos series from Exynos4X12 because supporting DMA.
The G2D is performed by two tasks simply.
1. Configures the rendering parameters, such as foreground color and
coordinates data by setting the drawing context registers.
2. Start the rendering process by setting thre relevant command
registers accordingly.
The G2D version 4.1 supports DMA mode as host interface. User can make
command list to reduce HOST(ARM) loads. The contents of The command list
is setted to relevant registers of G2D by DMA.
The command list is composed Header and command sets and Tail.
- Header: The number of command set(4Bytes)
- Command set: Register offset(4Bytes) + Register data(4Bytes)
- Tail: Pointer of base address of the other command list(4Bytes)
By Tail field, the G2D can process many command lists without halt at
one go.
The G2D has following the rendering pipeline.
--> Primitive Drawing --> Rotation --> Clipping --> Bilinear Sampling
--> Color Key --> ROP --> Mask Operation --> Alpha Blending -->
Dithering --> FrameBuffer
And supports various operations from the rendering pipeline.
- copy
- fast solid color fill
- window clipping
- rotation
- flip
- 4 operand raster operation(ROP4)
- masking operation
- alpha blending
- color key
- dithering
- etc
User should make the command list to data and registers needed by
operation to use. The Exynos G2D driver only manages the command lists
received from user. Some registers needs memory base address(physical
address) of image. User doesn't know its physical address, so fills the
gem handle of that memory than address to command sets, then G2D driver
converts it to memory base address.
We adds three ioctls and one event for Exynos G2D.
- ioctls
DRM_EXYNOS_G2D_GET_VER: get the G2D hardware version
DRM_EXYNOS_G2D_SET_CMDLIST: set the command list from user to driver
DRM_EXYNOS_G2D_EXEC: execute the command lists setted to driver
- event
DRM_EXYNOS_G2D_EVENT: event to give notification completion of the
command list to user

drm/exynos: added vp scaling feature for hdmi
This patch adds vp scaling feature for exynos hdmi. Scaling ratio
between source and destination is used for width and height.
Also meaningless variables to set registers are cleaned.

drm/radeon: make use of radeon_gem_init() consistent
All radeon_gem_init() does is initialize the gem objects
list. radeon_device.c does this explicitly. r600+ calls
radeon_gem_init() so the list gets initialized twice. Older
asics don't call it at all and rely on the the init in
radeon_device.c. Just call radeon_gem_init() in radeon_device.c
and remove the explicit calls from all the newer asics.
All asics call radeon_gem_fini() in their fini pathes. That
could possibly be cleaned up too.
