First drm-misc pull req for 4.6. Big one is the drm_event cleanup, which
is also prep work for adding android fence support to kms (Gustavo is
planning to do that). Otherwise random small bits all over.

gma500: clean up an excessive and confusing helper

drm/vmwgfx: Nuke preclose hook

drm/gma500: Remove empty preclose hook
...
There's really no reason to not do so, instead of replicating this
for every use-case and every driver. Now we can't just nuke the events,
since that would still mean that all drm_event users would need to know
when that has happened, since calling e.g. drm_send_event isn't allowed
any more. Instead just unlink them from the file, and detect this case
and handle it appropriately in all functions.
v2: Adjust existing kerneldoc too.
v3: Improve wording of the kerneldoc and split out vblank cleanup (Laurent).

Well we can't use that directly since that code must hold
dev->event_lock already. Extract an _unlocked version.

displayport multistream fixes from AMD.
* 'drm-fixes-mst' of git://people.freedesktop.org/~airlied/linux:
drm/dp/mst: deallocate payload on port destruction
drm/dp/mst: Reverse order of MST enable and clearing VC payload table.
drm/dp/mst: move GUID storage from mgr, port to only mst branch
drm/dp/mst: change MST detection scheme
drm/dp/mst: Calculate MST PBN with 31.32 fixed point
drm: Add drm_fixp_from_fraction and drm_fixp2int_ceil
drm/mst: Add range check for max_payloads during init
drm/mst: Don't ignore the MST PBN self-test result
drm: fix missing reference counting decrease
Previous implementation does not handle case below: boot up one MST branch
to DP connector of ASIC. After boot up, hot plug 2nd MST branch to DP output
of 1st MST, GUID is not created for 2nd MST branch. When downstream port of
2nd MST branch send upstream request, it fails because 2nd MST branch GUID
is not available.
New Implementation: only create GUID for MST branch and save it within Branch.

drm_fixp_from_fraction allows us to create a fixed point directly
from a fraction, rather than creating fixed point values and dividing
later. This avoids overflow of our 64 bit value for large numbers.
drm_fixp2int_ceil allows us to return the ceiling of our fixed point
value.

The Rockchip driver cannot use drm_atomic_helper_wait_for_vblanks()
because it has hardware counters for neither vblanks nor scanlines.
In order to simplify re-implementing the functionality for this driver,

We want this for consistency with existing page_flip semantics.
Since this spurred quite a discussion on IRC also document why we
reject event generation when the pipe is off: It's not that it's hard
to implement, but userspace has a track recording which proves that it's
way too easy to accidentally abuse and cause havoc. We want to make
sure userspace doesn't get away with that.
v2: Somehow thought we do reject events already, but that code only
existed in my imagination ... Also suggestions from Thierry.

drm_dev_set_unique() uses a format string to define the unique name of a
device. This feature is not used as currently all the calls to this
function either use "%s" as a format string or directly use
dev_name().
Even though this second kind of call does not introduce security
problems, because there cannot be "%" characters in dev_name() results,
gcc issues a warning when building with -Wformat-security flag
("warning: format string is not a string literal (potentially
insecure)"). This warning is useful to find real bugs like the one
fixed by commit 3958b79266 ("configfs: fix kernel infoleak through
user-controlled format string"). False positives which do not bring
an extra value make the work of finding real bugs harder.
Therefore remove the format-string feature from drm_dev_set_unique().

MODE_UNVERIFIED actually means that the mode came from a previous probe,
and if the new probe doesn't produce a matching mode it will get pruned
from the list. Rename the flag to MODE_STALE to better convey the
meaning.

Done with coccinelle for the most part. It choked on

"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

I didn't convert drm_plane_init() since passing the varargs through

care about these legacy functions enough to warrant the extra pain.

Implement a new i915_audio_component_ops, get_eld(). It's called by
the audio driver to fetch the current audio status and ELD of the
given HDMI/DP port. It returns the size of expected ELD bytes if it's
valid, zero if no valid ELD is found, or a negative error code. The
current state of audio on/off is stored in the given pointer, too.
Note that the returned size isn't limited to the given max bytes. If
the size is greater than the max bytes, it means that only a part of
ELD has been copied back.
For achieving this implementation, a new field audio_connector is
added to struct intel_digital_port. It points to the connector
assigned to the given digital port. It's set/reset at each audio
enable/disable call in intel_audio.c, and protected with av_mutex.

This adds code to initialise the SDP streams

I've no idea how you'd want to control the
ordering at this level, so don't bother
until someone comes up with a use case.

While typing these I noticed that ->dirty is a bit a can of worms
and even supports blt/fill semantics ... shocked me a bit.
Oh well it's defined in a way that nothing bad (just a bit of inefficiency)
will happen for drivers which supports this. So I didn't bother copying
the detailed spec into the new kerneldoc.

And merge any docbook we have into the kerneldoc comments.
Since it's a legacy entry point with only two implementation (one each
in atomic and legacy crtc helpers) I've made the documentation for
set_config fairly sparse - no one should ever need to look at this
again, all the ABI we have is baked into code.
For ->page_flip otoh I kept all the extensive docs from the docbook
and even extended it where it was lacking: Currently we have a pile of
legacy page_flip implemantations, and even for atomic drivers there's
not yet a standard implementation in the helpers. Which means every
driver needs to implement this itself, and precise specs are really
valuable.
Otherwise there's just cursor, which really just boils down to "use at
least universal planes". And gamma tables (where we have a bit a mess
with the fbdev helper gamma hooks).
v2: Spelling fixes (Eric).
v3: Suggestions from Thierry.

The special case here is that both ->detect and ->force are actually
functions only called by the probe helpers and hence really shouldn't
be here. But since they've used by pretty much every driver I figured
it's better to just document this for now instead of holding this doc
patch hostage until that's all fixed. For that reason also group force
right next to detect.
v2: Use FIXME comments to annotate where we should move a hook to
helpers.
