a4a027a860 drm/i915/kbl: Introduce the first official DMC for Kabylake. 
Version 1.01.

This firmware is made for Kabylake platform so it doesn't
need the stepping workaround that we had before.

v2: Rebased on top of latest nightly with min version
    required change.
v3: With right CSR_VERSION (Patrik).

a87848750e drm/i915: Set legacy properties when using legacy gamma set IOCTL. (v2) 
The i915 driver is now using atomic properties and atomic commit
to handle the legacy set gamma IOCTL. However, if the driver is
configured without atomic (nuclear_pageflip = false), it won't
update the legacy properties for degamma_lut, gamma_lut and ctm
leaving them out of sync with the atomic version of the properties.

Until the driver is full atomic, make sure we update the non-atomic
version of the properties.

v2: Update the comment with a FIXME.  (Daniel)

v3: Update arguments of the gamma_set vfunc (Lionel)

v4: Fixed vfunc prototype (Lionel)

ed2eebbd61 drm/i915: add missing condition for committing planes on crtc 
The i915 driver checks for color management properties changes as part
of a plane update. Therefore a color management update must imply a
plane update, otherwise we never update the transformation matrixes
and degamma/gamma LUTs.

v2: add comment about moving the commit of color management registers
    to an async worker

v3: Commit color management register right after vblank

v4: Move back color management commit condition together with planes
    commit

v5: Trigger color management commit through the planes commit (Daniel)

v6: Make plane change update more readable

Fixes: 20a34e78f0 (drm/i915: Update color management during vblank evasion.)

c71d4d5898 drm/i915: Treat eDP as always connected, again 
eDP should be treated as connected even if doesn't have an EDID. In that
case we'll use the timings from the VBT. That used to be the case until
commit f21a21983e ("drm/i915: Splitting intel_dp_detect")
broke things by considering even eDP disconnected if we fail to get
an EDID for it.

Fix things up again by treating eDP as always connected.

4077798484 drm/vgem: Attach sw fences to exported vGEM dma-buf (ioctl) 
vGEM buffers are useful for passing data between software clients and
hardware renders. By allowing the user to create and attach fences to
the exported vGEM buffers (on the dma-buf), the user can implement a
deferred renderer and queue hardware operations like flipping and then
signal the buffer readiness (i.e. this allows the user to schedule
operations out-of-order, but have them complete in-order).

This also makes it much easier to write tightly controlled testcases for
dma-buf fencing and signaling between hardware drivers.

v2: Don't pretend the fences exist in an ordered timeline, but allocate
a separate fence-context for each fence so that the fences are
unordered.
v3: Make the debug output more interesting, and show the signaled status.
v4: Automatically signal the fence to prevent userspace from
indefinitely hanging drivers.

1d926114d8 drm: rcar-du: Remove i2c slave encoder interface for hdmi encoder 
The hdmi output in rcar-du uses the i2c slave encoder interface to link

entities that internally uses the drm_encoder_slave_funcs ops provided by
the slave encoder driver.

Change the driver such that it expects a bridge entity instead of a slave
encoder. The hdmi connector code isn't needed anymore as we expect the
adv7511 bridge driver to create/manage the connector.

Note that the kms driver still expects a connector node for hdmi to be
present in DT. This node has no connection to the connector created
by the bridge driver.

79c21187ca drm/msm/rd: add module param to dump all bo's 
By default, if using $debugfs/.../rd to log cmdstream, only the
cmdstream buffers themselves are logged.  But in some cases we want
to capture other buffers in the submit (to see VBO's or shaders).
So add a mod-param knob to control this.
