Bspec says:
"Restriction : SRD must not be enabled when the PSR Setup time from DPCD
00071h is greater than the time for vertical blank minus one line."
Let's check for that and disallow PSR if we exceed the limit.

The page aligned surface address calculation needs to know which way
things are rotated. The contract now says that the caller must pass the
rotate x/y coordinates, as well as the tile_height aligned stride in

90/270 degree rotation on SKL+ where we have to deal with the rotated

Here are the patchset to add get_eld op to audio component for
communicating more directly between i915 and HD-audio.
Currently, the HDMI/DP audio status and ELD are notified and obtained
via the hardware-level communication over HD-audio unsolicited event
and verbs although the graphics driver holds the exactly same
information. As we already have a notification via audio component,
this is another step forward; namely, the audio driver may fetch
directly the audio status and ELD via the new component op.
The commits are based on Dave's latest drm-next branch.

Done with coccinelle for the most part. It choked on
msm/mdp/mdp5/mdp5_plane.c like so:
"BAD:!!!!! enum drm_plane_type type;"
No idea how to deal with that, so I just fixed that up
by hand.
Also it thinks '...' is part of the semantic patch, so I put an
'int DOTDOTDOT' placeholder in its place and got rid of it with
sed afterwards.
I didn't convert drm_plane_init() since passing the varargs through
would mean either cpp macros or va_list, and I figured we don't
care about these legacy functions enough to warrant the extra pain.

The cherryview device shares many characteristics with the valleyview
device. When support was added to the driver for cherryview, the
corresponding device info structure included .is_valleyview = 1.
This is not correct and leads to some confusion.
This patch changes .is_valleyview to .is_cherryview in the cherryview
device info structure and simplifies the IS_CHERRYVIEW macro.
Then where appropriate, instances of IS_VALLEYVIEW are replaced with
IS_VALLEYVIEW || IS_CHERRYVIEW or equivalent.
v2: Use IS_VALLEYVIEW || IS_CHERRYVIEW instead of defining a new macro.
Also add followup patches to fix issues discovered during the first

then performs a regular watermark update. However intel_plane->wm is
only used to update a couple fields in intel_wm_config, and those fields

Unfortunately fbc still depends on legacy primary state, so
it can't be killed off completely yet.

This makes the error message slightly more useful.

- Use ktime_get() while irqs are still disabled. (vsyrjala)

[danvet: Squash in follow-up to also remove start_vbl_count from
intel_crtc->atomic and put it into the intel_crtc directly - it's not

In order to get decnet memory self refresh residency on VLV, flip it
over to the new CHV way of doing things. VLV doesn't do PM5 or DDR DVFS
so it's a bit simpler.
I'm not sure the currently memory latency used for CHV is really
appropriate for VLV. Some further testing will probably be needed to
figure that out.

Avoid some 'switch (plane->type)' by storing the fronbuffer_bits in

[danvet: use singular frontbuffer_bits in intel_plane since a plan can

By making color key atomic there are no more transitional helpers.
The plane check function will reject the color key when a scaler is
active.

Now that all planes are added during a modeset we can use the
calculated changes before disabling a plane, and then either commit
or force disable a plane before disabling the crtc.
The code is shared with atomic_begin/flush, except watermark updating
and vblank evasion are not used.
This is needed for proper atomic suspend/resume support.

The idea was good, but planes can have a fb even though
they're disabled. This makes the force argument useless
and always true, because only the commit function updates
state.

By passing crtc_state to the check_plane functions a lot of duplicated
code can be removed. There are still some transitional helper calls,
they will be removed later.
Changes since v1:
- Revert state->visible changes.
- Use plane->state->crtc instead of plane->crtc.
- Use drm_atomic_get_existing_crtc_state.
