Baoyou Xie 297b12862d drm/radeon: add missing header dependencies
We get a few warnings when building kernel with W=1:
drivers/gpu/drm/radeon/radeon_clocks.c:35:10: warning: no previous prototype for 'radeon_legacy_get_engine_clock' [-Wmissing-prototypes]
drivers/gpu/drm/radeon/atombios_encoders.c:75:1: warning: no previous prototype for 'atombios_get_backlight_level' [-Wmissing-prototypes]
drivers/gpu/drm/radeon/r600_cs.c:2268:5: warning: no previous prototype for 'r600_cs_parse' [-Wmissing-prototypes]
drivers/gpu/drm/radeon/evergreen_cs.c:2671:5: warning: no previous prototype for 'evergreen_cs_parse' [-Wmissing-prototypes]
....

In fact, these functions are declared
in drivers/gpu/drm/radeon/radeon_asic.h,
so this patch adds missing header dependencies.

Mario Kleiner 459ee1c3fd drm/radeon: Don't drop DP 2.7 Ghz link setup on some cards.
As observed on Apple iMac10,1, DCE-3.2, RV-730,
link rate of 2.7 Ghz is not selected, because
the args.v1.ucConfig flag setting for 2.7 Ghz
gets overwritten by a following assignment of
the transmitter to use.

Move link rate setup a few lines down to fix this.
In practice this didn't have any positive or
negative effect on display setup on the tested
iMac10,1 so i don't know if backporting to stable
makes sense or not.

we use for determining connectedness and when to enable certain
features like hdmi audio, etc.  When the user uses the firmware

is a user supplied edid and update the driver's copy if there
is.

Alex Deucher da9976206c drm/radeon: enable display scaling on all connectors (v2)
This enables the display scaler on all connectors for r5xx
and newer asics.  Previously we only enabled the scaler for
fixed mode displays (eDP or LVDS) since they have to use the
scaler to support non-native modes.  Most other displays
are multi-sync or have a built in scaler to support non-native
modes.  The default scaling mode for non-fixed displays is
none which will use the scaler in the monitor.  Note that
we do not populate any fake modes like we do for fixed
displays so it will only use the modes in the edid.  For
other modes, you'll need to populate them manually.

Dave Airlie 91915260ea Merge tag 'drm-intel-fixes-2013-11-07' of git://people.freedesktop.org/~danvet/drm-intel into drm-next
Bit a bit -fixes pull request in the merge window than usual dua to two
feauture-y things:
- Display CRCs are now enabled on all platforms, including the odd DP case
  on gm45/vlv. Since this is a testing-only feature it should ever hurt,
  but I figured it'll help with regression-testing -fixes. So I left it
  in and didn't postpone it to 3.14.
- Display power well refactoring from Imre. Would have caused major pain
  conflict with the bdw stage 1 patches if I'd postpone this to -next.
  It's only an relatively small interface rework, so shouldn't cause pain.
  It's also been in my tree since almost 3 weeks already.

That accounts for about two thirds of the pull, otherwise just bugfixes:
- vlv backlight fix from Jesse/Jani
- vlv vblank timestamp fix from Jesse
- improved edp detection through vbt from Ville (fixes a vlv issue)
- eDP vdd fix from Paulo
- fixes for dvo lvds on i830M
- a few smaller things all over

Note: This contains a backmerge of v3.12. Since the -internal branch
always applied on top of -nightly I need that unified base to merge bdw
patches. So you'll get a conflict with radeon connector props when pulling
this (and nouveau/master will also conflict a bit when Ben doesn't
rebase). The backmerge itself only had conflicts in drm/i915.

There's also a tiny conflict between Jani's backlight fix and your sysfs
lifetime fix in drm-next.

Dave Airlie 5bdebb183c drm/sysfs: sort out minor and connector device object lifetimes.
So drm was abusing device lifetimes, by having embedded device structures
in the minor and connector it meant that the lifetime of the internal drm
objects (drm_minor and drm_connector) were tied to the lifetime of the device
files in sysfs, so if something kept those files opened the current code
would kfree the objects and things would go downhill from there.

Now in reality there is no need for these lifetimes to be so intertwined,
especailly with hotplugging of devices where we wish to remove the sysfs
and userspace facing pieces before we can unwind the internal objects due
to open userspace files or mmaps, so split the objects out so the struct
device is no longer embedded and do what fbdev does and just allocate
and remove the sysfs inodes separately.

Alex Deucher 108dc8e8b4 drm/radeon: rework audio option
In 3.12 I changed audio to be enabled by default,
but you still had to turn it on via xrandr.  This
was confusing to users so change it to minic the
previous behavior:

- audio option is set to -1 (auto) by default which is
  the current 3.12 behavior (audio is enabled but requires
  xrandr to turn it on).
- if audio = 1, the audio is enabled without needing
  to mess with xrandr (previous behavior)
- audio = 0 disables audio

It retains the new feature of allowing the user to enable
audio on the fly with xrandr, but turns audio on
automatically if radeon.audio=1 is set which is what
most users expect.

Alex Deucher 91f3a6aaf2 drm/radeon/atom: workaround vbios bug in transmitter table on rs880 (v2)
The OUTPUT_ENABLE action jumps past the point in the coder where
the data_offset is set on certain rs780 cards.  This worked
previously because the OUTPUT_ENABLE action is always called
immediately after the ENABLE action so the data_offset remained
set.  In 6f8bbaf568c7f2c497558bfd04654c0b9841ad57
(drm/radeon/atom: initialize more atom interpretor elements to 0),
we explictly reset data_offset to 0 between atom calls which then
caused this to fail.  The fix is to just skip calling the
OUTPUT_ENABLE action on the problematic chipsets.  The ENABLE
action does the same thing and more.  Ultimately, we could
probably drop the OUTPUT_ENABLE action all together on DCE3
asics.

Linus Torvalds 612a9aab56 Merge branch 'drm-next' of git://people.freedesktop.org/~airlied/linux
Pull drm merge (part 1) from Dave Airlie:
 "So first of all my tree and uapi stuff has a conflict mess, its my
  fault as the nouveau stuff didn't hit -next as were trying to rebase
  regressions out of it before we merged.

  Highlights:
   - SH mobile modesetting driver and associated helpers
   - some DRM core documentation
   - i915 modesetting rework, haswell hdmi, haswell and vlv fixes, write
     combined pte writing, ilk rc6 support,
   - nouveau: major driver rework into a hw core driver, makes features
     like SLI a lot saner to implement,
   - psb: add eDP/DP support for Cedarview
   - radeon: 2 layer page tables, async VM pte updates, better PLL
     selection for > 2 screens, better ACPI interactions

  The rest is general grab bag of fixes.

  So why part 1? well I have the exynos pull req which came in a bit
  late but was waiting for me to do something they shouldn't have and it
  looks fairly safe, and David Howells has some more header cleanups
  he'd like me to pull, that seem like a good idea, but I'd like to get
  this merge out of the way so -next dosen't get blocked."

Tons of conflicts mostly due to silly include line changes, but mostly
mindless.  A few other small semantic conflicts too, noted from Dave's
pre-merged branch.
