2016-07-18drm/i915/kbl: Introduce the first official DMC for Kabylake.Rodrigo Vivi
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).

2016-07-18drm/i915: add missing condition for committing planes on crtcLionel Landwerlin
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: 20a34e78f0d7 (drm/i915: Update color management during vblank evasion.)

2016-07-18drm/i915: Treat eDP as always connected, againVille Syrjälä
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 f21a21983ef1 ("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.

2016-07-18drm/vgem: Attach sw fences to exported vGEM dma-buf (ioctl)Chris Wilson
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.

2016-07-18drm: rcar-du: Remove i2c slave encoder interface for hdmi encoderArchit Taneja
The hdmi output in rcar-du uses the i2c slave encoder interface to link to the adv7511 encoder chip. The kms driver creates encoder and connector 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.
