git://anongit.freedesktop.org/drm-intel into drm-next
Final drm-misc pull for 4.0, just various things all over, including a few
more important atomic fixes. btw I didn't pick up the vmwgfx patch from
Ville's series, but one patch has one hunk touching vmwgfx and
Thomas/Jakob didn't get around to ack it. I figured it's simple enough to
be ok though.

We don't currently have cdclk extraction code for 965g,snb,ivb.

Based on the BIOS DP A AUX 2x clock divider the cdclk frequency
on ILK is 450Mhz. At least that holds on my ILK and it matches
how we program the divider.
Supposedly cdclk is 400MHz on SNB and IVB, again based on the AUX 2x
clock divider. Note that I don't have a SNB or IVB machine with
eDP so I couldn't verify what the BIOS used, so this notion is
purely based on our current code,

This patch allows to optionally attach the lvds-channel to a panel
supported by a drm_panel driver using of-graph bindings, instead of
supplying the modes via display-timings in the device tree.
This depends on of_graph_get_port_by_id and uses the OF graph to
link the optional DRM panel to the LDB lvds-channel. The output
port number is 1 on devices without the 4-port input multiplexer
(i.MX5) and 4 on devices with the mux (i.MX6).
Before:
ldb {
...
lvds-channel@0 {
...
display-timings {
native-timing = <&timing1>;
timing1: etm0700g0dh6 {
hactive = <800>;

vback-porch = <33>;
vfront-porch = <10>;
hsync-active = <0>;
vsync-active = <0>;
...
};
};
...

port@4 {

Patch derived from one from Yakir Yang. Yakir Yang says:
For Designerware HDMI, the following write sequence is recommended:
1. aud_n3 (set bit ncts_atomic_write if desired)
2. aud_cts3 (set CTS_manual and CTS value if desired/enabled)
3. aud_cts2 (required in CTS_manual)
4. aud_cts1 (required in CTS_manual)
5. aud_n3 (bit ncts_atomic_write with same value as in step 1.)
6. aud_n2
7. aud_n1
However, avoid the ncts_atomic_write_bit and CTS_manual settings in this
patch, both of which are marked reserved in the iMX6 documentation. All
iMX6 code in the wild seems to want CTS_manual cleared.
Having requested clarification from FSL, it appears that neither of
these bits are implemented in their version of the IP.

The HDMI n/cts settings need to be updated whenever the audio sample
rate or the video pixel clock changes. This needs to be protected
against concurrency as there is no synchronisation between these two
operations. Introduce a mutex (called audio_mutex) to protect against
two threads trying to update the video clock rate and pixel clock
simultaneously.

Users of the atomic state assume that if the pointer to a crtc, plane or
connector is not NULL in the respective object vector, than the state
for that object in *_states vector also won't be NULL. That assumption
was broken by drm_atomic_state_clear(), which would clear the state
pointer but leave the pointer to the object still set.
This fixes a NULL pointer dereference in i915 caused by the use of
drm_atomic_state_clear().

To allow for views where the view type is not defined by the view type only,
like it is in stereo or rotated 90 degree view, change the semantic to require
the whole view structure for comparison when we match a GGTT view.
This allows including parameters like offset to be included in the view which
is useful for eg. partial views.
v3:
- Rely on ggtt_view type being 0 for non-GGTT vma's, which equals to
I915_GGTT_VIEW_NORMAL. (Daniel Vetter)
- Do not use potentially slower comparison when we only want to know if
something is or is not a normal view.
- Rebase on top of rotated view patches. Add rotated view singleton.
- If one view is missing in comparison they're equal only if both are missing.
v4:
- Use comparison helper in obj_to_ggtt_view too. (Tvrtko Ursulin)
- Do WARN_ON if one view is NULL. (Tvrtko Ursulin)

Legacy setCrtc has a nice fastpath for just updating the frontbuffer
when the output routing doesn't change. Which I of course tried to
keep working, except that I fumbled the job: The helpers correctly
compute ->mode_changed, CRTC updates get correctly skipped but
connector functions are called unconditionally.
Fix this.
v2: For the disable sided connector->state->crtc might be NULL.
Instead look at the old_connector_state->crtc, but still use the new
crtc state for that old crtc. Reported by Thierry.
