Dave Airlie cad7d8d904 Merge tag 'topic/kbl-4.7-fixes-2016-07-18' of git://anongit.freedesktop.org/drm-intel into drm-fixes 
As promised here's the pile of kbl cherry-picks assembled by Mika&Rodrigo.
It's a bit much, but all well-contained to kbl code and been tested for a
while in drm-intel-next. Still separate in case too much, but in that case
I think we'd need to disable kbl by default again (which would be annoying
too) in 4.7.

Rodrigo Vivi 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).

Lionel Landwerlin 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.)

Ville Syrjälä 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.

Rodrigo Vivi bc7135b9a4 drm/i915: Introduce Kabypoint PCH for Kabylake H/DT. 
Some Kabylake SKUs are going to use Kabypoint PCH.
It is mainly for Halo and DT ones.

>From our specs it doesn't seem that KBP brings
any change on the display south engine. So let's consider
this as a continuation of SunrisePoint, i.e., SPT+.

Since it is easy to get confused by a letter change:
KBL = Kabylake - CPU/GPU codename.
KBP = Kabypoint - PCH codename.
