9af07af948 Merge tag 'topic/drm-misc-2016-07-22' of git://anongit.freedesktop.org/drm-intel into drm-next
Suddenly everyone shows up with their trivial patch series!
- piles of if (!ptr) check removals from Markus Elfring
- more of_node_put fixes from Peter Chen
- make fbdev support really optional in all drivers (except vmwgfx),
  somehow this fell through the cracks when we did all the hard prep work
  a while ago. Patches from Tobias Jakobi.
- leftover patches for the connector reg/unreg cleanup (required that I
  backmerged drm-next) from Chris
- last vgem fence patch from Chris
- fix up warnings in the new sphinx gpu docs build
- misc other small bits

dc96fe4f85 drm/sun4i: Remove redundant call to drm_connector_unregister_all()
drm_connector_unregister_all() is automatically called by
drm_dev_unregister() and so the manual call can be dropped.

a742946a1b drm: Don't call drm_dev_set_unique from platform drivers
Since

commit e112e593b2
Author: Nicolas Iooss <nicolas.iooss_linux@m4x.org>
Date:   Fri Dec 11 11:20:28 2015 +0100

    drm: use dev_name as default unique name in drm_dev_alloc()

we're using a reasonable default which should work for everyone. Only
mtk, rcar-du and sun4i are affected, and as kms-only drivers without
any rendering support no one should ever care about the unique name

v2: Rebase on top of mediatek.

3d6bd9065b drm/sun4i: remove simplefb at probe
If simplefb was setup by our bootloader and enabled in the DT, we will have
a first framebuffer loaded in our system.

However, as soon as our DRM driver will load, it will reset the controller,
initialise it and, if the framebuffer emulation is enabled, register a
second framebuffer device.

This is obviously pretty bad, since the first framebuffer will be some kind
of a black hole, with memory still reserved that we can write to safely,
but not displayed anywhere.

Make sure we remove that framebuffer when we probe so we don't end up in
that situation.

29e57fab97 drm: sun4i: Add RGB output
One of the A10 display pipeline possible output is an RGB interface to
drive LCD panels directly. This is done through the first channel of the
TCON that will output our video signals directly.

9026e0d122 drm: Add Allwinner A10 Display Engine support
The Allwinner A10 and subsequent SoCs share the same display pipeline, with
variations in the number of controllers (1 or 2), or the presence or not of
some output (HDMI, TV, VGA) or not.

Add a driver with a limited set of features for now, and we will hopefully
support all of them eventually
