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.

f07df98063 drm/rcar-du: 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.

fef1ac57af rcar-du: add/rename DEFR6 TCON bits
The  TCNE2 bit  of the DEFR6 register was renamed to TCNE1 in the R-Car gen2
manuals -- which makes more  sense as that bit controls whether DU1, not DU2
is connected to TCON.

While at it, add the TCNE0 bit which controls whether DU0 is connected to
TCON.

2cca455740 Merge tag 'topic/drm-misc-2016-06-07' of git://anongit.freedesktop.org/drm-intel into drm-next
As promised, piles of prep work all around:
- drm_atomic_state rework, prep for nonblocking commit helpers
- fence patches from Gustavo and Christian to prep for atomic fences and
  some cool work in ttm/amdgpu from Christian
- drm event prep for both nonblocking commit and atomic fences
- Gustavo seems on a crusade against the non-kms-native version of the
  vblank functions.
- prep work from Boris to nuke all the silly ->best_encoder
  implementations we have (we really only need that for truly dynamic
  cases like dvi-i vs dvi-d or dp mst selecting the right transcoder on
  intel)
- prep work from Laurent to rework the format handling functions
- and few small things all over

21daaeee9f Merge tag 'topic/drm-misc-2016-05-04' of git://anongit.freedesktop.org/drm-intel into drm-next
Ofc I promise just a few leftovers for drm-misc and somehow it's the
biggest pull. But really mostly trivial stuff:
- MAINTAINERS updates from Emil
- rename async to nonblock in atomic_commit to avoid the confusion between
  nonblocking ioctl and async flip (= not vblank synced), from Maarten.
  Needs to be regened with newer drivers, but probably only after -rc1 to
  catch them all.
- actually lockless gem_object_free, plus acked driver conversion patches.
  All the trickier prep stuff already is in drm-next.
- Noralf's nice work for generic defio support in our fbdev emulation.
  Keeps the udl hack, and qxl is tested by Gerd.

4f5504cfc6 drm: rcar-du: Clarify vsp dependency
The VSP1 compositor code in DRM links against the respective V4L
driver, but the dependency is not expressed correctly in Kconfig,
which leads to a build error when the DRM driver is built-in
and the V4L driver is a module:

drivers/gpu/built-in.o: In function `rcar_du_vsp_plane_atomic_update':
rcar-du/rcar_du_vsp.c:183: undefined reference to `vsp1_du_atomic_update'

This patch avoids the problem by ensuring that the DRM VSP code can
only be enabled if the V4L driver is linked into the kernel, or
both are loadable modules.

6d62ef3ac3 drm: rcar-du: Expose the VSP1 compositor through KMS planes
On R-Car Gen3 SoCs the DU lost its ability to access memory directly and
needs to work in conjunction with the VSP to do so. This commit handles
the VSP internally to hide it from the user.

ab334e137c drm: rcar-du: Move plane allocator to rcar_du_plane.c
The plane allocator is specific to DU planes and won't be used for
VSP-based planes, move it with the rest of the DU planes code where it
belongs.

2af0394409 drm: rcar-du: Restart the DU group when a plane source changes
Plane sources are configured by the VSPS bit in the PnDDCR4 register.
Although the datasheet states that the bit is updated during vertical
blanking, it seems that updates only occur when the DU group is held in
reset through the DSYSR.DRES bit. Restart the group if the source
changes.

af8ad96290 drm: rcar-du: Add VSP1 support to the planes allocator
The R8A7790 DU can source frames directly from the VSP1 devices VSPD0
and VSPD1. VSPD0 feeds DU0/1 plane 0, and VSPD1 feeds either DU2 plane 0
or DU0/1 plane 1.

Allocate the correct fixed plane when sourcing frames from VSPD0 or
VSPD1, and allocate planes in reverse index order otherwise to ensure
maximum availability of planes 0 and 1.

2f13c5296d drm: rcar-du: Refactor plane setup
Rename plane setup functions using more explicit names, and use local
variables to store intermediate values to increase readability. This
also prepares for VSP compositor support.

1b0fd0ea49 drm: rcar-du: Don't update planes on disabled CRTCs
A disabled CRTC can't display planes, the driver shouldn't try to
configure it when updating planes. The DRM core will store the plane
state for us, and the plane will be configured appropriately the next
time the CRTC is enabled.

6ea22ab4a0 drm: rcar-du: Remove local CRTC enabled state
The atomic framework guarantees that the CRTC enable and disable
functions will only be called when needed, there's no need to duplicate
the CRTC state check. By replacing the local CRTC enabled state check at
resume time with the CRTC active state we can remove the local CRTC
enabled state altogether.

c1d4b38c93 drm: rcar-du: Perform initialization/cleanup at probe/remove time
The drm driver .load() operation is prone to race conditions as it
initializes the driver after registering the device nodes. Its usage is
deprecated, inline it in the probe function and call drm_dev_alloc() and
drm_dev_register() explicitly.

For consistency inline the .unload() handler in the remove function as
well.

is also prep work for adding android fence support to kms (Gustavo is
planning to do that). Otherwise random small bits all over.

Again since the drm core takes care of event unlinking/disarming this
is now just needless code.
