31ad61e4af drm: BIT(DRM_ROTATE_?) -> DRM_ROTATE_?
Only property creation uses the rotation as an index, so convert the
to figure the index when needed.

v2: Use the new defines to build the _MASK defines (Sean)

2383050f6a Merge remote-tracking branch 'airlied/drm-next' into topic/drm-misc
Backmerge drm-next to be able to apply Chris' connector_unregister_all
cleanup (need latest i915 and sun4i state for that).

Also there's a trivial conflict in ttm_bo.c that git rerere fails to
remember.

5de10e9dc6 drm/atmel-hlcdc: make fbdev support really optional
Currently enabling ATMEL HLCDC DRM support automatically pulls
in fbdev dependency. However this dep is unnecessary since

99e6fe5076 drm/atmel-hlcdc: Remove redundant calls to drm_connector_register_all()
Up to now, the recommendation was for drivers to call drm_dev_register()
followed by drm_connector_register_all(). Now that
drm_connector_register() is safe against multiple invocations, we can
move drm_connector_register_all() to drm_dev_register() and not suffer
from any backwards compatibility issues with drivers not following the
more rigorous init ordering.

aca63b7661 drm: atmel-hlcdc: move output mode selection in CRTC implementation
In order to support multiple outputs we need to move the output mode
selection to the CRTC object, so that the output validity check can be
done against the drm_atomic_state.

If the connectors selected by a specific mode setting are requiring
incompatible bus format the atomic operation is aborted (->atomic_check()
returns -EINVAL).

In order to implement that, we need to define our own CRTC state and
overload default ->reset(), ->atomic_duplicate_state() and
->atomic_destroy_state() functions.

e112e593b2 drm: use dev_name as default unique name in drm_dev_alloc()
The following code pattern exists in some DRM drivers:

    ddev = drm_dev_alloc(&driver, parent_dev);
    drm_dev_set_unique(ddev, dev_name(parent_dev));

(Sometimes dev_name(ddev->dev) is used, which is the same.)

As suggested in
http://lists.freedesktop.org/archives/dri-devel/2015-December/096441.html,
the unique name of a new DRM device can be set as dev_name(parent_dev)
when parent_dev is not NULL (vgem is a special case).

b0b3b79511 drm: Pass 'name' to drm_universal_plane_init()
Done with coccinelle for the most part. It choked on
msm/mdp/mdp5/mdp5_plane.c like so:
"BAD:!!!!!  enum drm_plane_type type;"
No idea how to deal with that, so I just fixed that up
by hand.

Also it thinks '...' is part of the semantic patch, so I put an
'int DOTDOTDOT' placeholder in its place and got rid of it with
sed afterwards.

I didn't convert drm_plane_init() since passing the varargs through
would mean either cpp macros or va_list, and I figured we don't
care about these legacy functions enough to warrant the extra pain.

b44f84081b drm: Stop using drm_vblank_count() as the hw frame counter
drm_vblank_count() returns the software counter. We should not pretend
it's the hw counter since we use the hw counter to figuere out what the
software counter value should be. So instead provide a new function
drm_vblank_no_hw_counter() for drivers that don't have a real hw
counter. The new function simply returns 0, which is about the only
thing it can do.
