Pull drm updates from Dave Airlie:
 "I Was Almost Tempted To Capitalise Every Word, but then I decided I
  couldn't read it myself!

  I've also got one pull request for the sti driver outstanding.  It
  relied on a commit in Greg's tree and I didn't find out in time, that
  commit is in your tree now so I might send that along once this is
  merged.

  I also had the accidental misfortune to have access to a Skylake on my
  desk for a few days, and I've had to encourage Intel to try harder,
  which seems to be happening now.

  Here is the main drm-next pull request for 4.4.

<para>
New drivers that no longer rely on the services provided by the

device registration functions directly. The
<function>drm_dev_alloc()</function> function can be used to allocate
and initialize a new <structname>drm_device</structname> structure.
Drivers will typically want to perform some additional setup on this
structure, such as allocating driver-specific data and storing a
pointer to it in the DRM device's <structfield>dev_private</structfield>
field. Drivers should also set the device's unique name using the
<function>drm_dev_set_unique()</function> function. After it has been
set up a device can be registered with the DRM subsystem by calling
<function>drm_dev_register()</function>. This will cause the device to
be exposed to userspace and will call the driver's
<structfield>.load()</structfield> implementation. When a device is
removed, the DRM device can safely be unregistered and freed by calling
<function>drm_dev_unregister()</function> followed by a call to
<function>drm_dev_unref()</function>.

<title>Driver Load</title>
<para>
The <methodname>load</methodname> method is the driver and device
initialization entry point. The method is responsible for allocating and
initializing driver private data, performing resource allocation and
mapping (e.g. acquiring
clocks, mapping registers or allocating command buffers), initializing
the memory manager (<xref linkend="drm-memory-management"/>), installing
the IRQ handler (<xref linkend="drm-irq-registration"/>), setting up
vertical blanking handling (<xref linkend="drm-vertical-blank"/>), mode
setting (<xref linkend="drm-mode-setting"/>) and initial output
configuration (<xref linkend="drm-kms-init"/>).
</para>
<note><para>
If compatibility is a concern (e.g. with drivers converted over from
User Mode Setting to Kernel Mode Setting), care must be taken to prevent
device initialization and control that is incompatible with currently
active userspace drivers. For instance, if user level mode setting
drivers are in use, it would be problematic to perform output discovery
&amp; configuration at load time. Likewise, if user-level drivers
unaware of memory management are in use, memory management and command
buffer setup may need to be omitted. These requirements are
driver-specific, and care needs to be taken to keep both old and new
applications and libraries working.
</para></note>
<synopsis>int (*load) (struct drm_device *, unsigned long flags);</synopsis>
<para>
The method takes two arguments, a pointer to the newly created
<structname>drm_device</structname> and flags. The flags are used to
pass the <structfield>driver_data</structfield> field of the device id
corresponding to the device passed to <function>drm_*_init()</function>.
Only PCI devices currently use this, USB and platform DRM drivers have
their <methodname>load</methodname> method called with flags to 0.

<title>Driver Private Data</title>

The driver private hangs off the main
<structname>drm_device</structname> structure and can be used for
tracking various device-specific bits of information, like register
offsets, command buffer status, register state for suspend/resume, etc.
At load time, a driver may simply allocate one and set
<structname>drm_device</structname>.<structfield>dev_priv</structfield>
appropriately; it should be freed and
<structname>drm_device</structname>.<structfield>dev_priv</structfield>
set to NULL when the driver is unloaded.

/**
* DOC: driver instance overview
*
* A device instance for a drm driver is represented by struct &drm_device. This
* is allocated with drm_dev_alloc(), usually from bus-specific ->probe()
* callbacks implemented by the driver. The driver then needs to initialize all
* the various subsystems for the drm device like memory management, vblank
* handling, modesetting support and intial output configuration plus obviously
* initialize all the corresponding hardware bits. An important part of this is
* also calling drm_dev_set_unique() to set the userspace-visible unique name of
* this device instance. Finally when everything is up and running and ready for
* userspace the device instance can be published using drm_dev_register().
*
* There is also deprecated support for initalizing device instances using
* bus-specific helpers and the ->load() callback. But due to
* backwards-compatibility needs the device instance have to be published too
* early, which requires unpretty global locking to make safe and is therefore
* only support for existing drivers not yet converted to the new scheme.
*
* When cleaning up a device instance everything needs to be done in reverse:
* First unpublish the device instance with drm_dev_unregister(). Then clean up
* any other resources allocated at device initialization and drop the driver's
* reference to &drm_device using drm_dev_unref().
*
* Note that the lifetime rules for &drm_device instance has still a lot of
* historical baggage. Hence use the reference counting provided by
* drm_dev_ref() and drm_dev_unref() only carefully.
*
* Also note that embedding of &drm_device is currently not (yet) supported (but
* it would be easy to add). Drivers can store driver-private data in the
* dev_priv field of &drm_device.
