7970e677ac drm: Add eDP connector type
Add a new connector type for eDP (embedded displayport)

eDP is more or less the same as DP but there are some
cases when you might want to handle it separately.

884840aa3c drm: Add dirty ioctl and property
This commit adds a ioctl and property to allow userspace
to notify the kernel that a framebuffer has changed. Instead
of snooping the command stream this allows finer grained
tracking of which areas have changed.

The primary user for this functionality is virtual hardware
like the vmware svga device, but also Xen hardware likes to
be notify. There is also real hardware like DisplayLink and
DisplayPort that might take advantage of this ioctl.

d91d8a3f88 drm/kms: add page flipping ioctl
This adds a page flipping ioctl to the KMS API.  The ioctl takes an fb ID
and a ctrc ID and flips the crtc to the given fb at the next vblank.
The ioctl returns immediately but the flip doesn't happen until after
any rendering that's currently queued up against the new framebuffer
is done.  After submitting a page flip, any execbuffer involving the
old front buffer will block until the flip is completed.

Optionally, a vblank event can be generated when the swap eventually
happens.

53bd83899f drm: clarify scaling property names
Now that we're using the scaling property in the Intel driver I noticed
that the names were a bit confusing.  I've corrected them according to
our discussion on IRC and the mailing list, though I've left out
potential new additions for a new scaling property with an integer (or
two) for the scaling factor.  None of the drivers implement that today,
but if someone wants to do it, I think it could be done with the
addition of a single new type and a new property to describe the
scaling factor in the X and Y directions.

74bd3c26b9 drm: Define DRM_MODE_CONNECTOR_TV
The existing TV connector types are often unsuitable either because
there is no way to probe them until they're actually plugged in or
because they can change during run time (e.g. 7-pin DIN connectors
that behave as S-Video, Component, Composite or SCART depending on the
adaptor plugged in).

1d7f83d5ad make drm headers use strict integer types
The drm headers are traditionally shared with BSD and
could not use the strict linux integer types. This is
over now, so we can use our own types now.

e0c8463a8b drm: sanitise drm modesetting API + remove unused hotplug
The initially merged modesetting API has some uglies in it, this
cleans up the struct members and ioctl ordering for initial submission.

It also removes the unneeded hotplug infrastructure.

airlied:- I've pulled this patch in from git modesetting-gem tree.

f453ba0460 DRM: add mode setting support
Add mode setting support to the DRM layer.

This is a fairly big chunk of work that allows DRM drivers to provide
full output control and configuration capabilities to userspace.  It was
motivated by several factors:
  - the fb layer's APIs aren't suited for anything but simple
    configurations
  - coordination between the fb layer, DRM layer, and various userspace
    drivers is poor to non-existent (radeonfb excepted)
  - user level mode setting drivers makes displaying panic & oops
    messages more difficult
  - suspend/resume of graphics state is possible in many more
    configurations with kernel level support

This commit just adds the core DRM part of the mode setting APIs.
Driver specific commits using these new structure and APIs will follow.
