Pull drm updates from Dave Airlie:
"This is the main drm pull, it has a shared branch with some alsa
crossover but everything should be acked by relevant people.

This patch is based on exynos-drm-next branch of Inki Dae's tree at:
git://git.kernel.org/pub/scm/linux/kernel/git/daeinki/drm-exynos.git
DECON(Display and Enhancement Controller) is the new IP
in exynos7 SOC for generating video signals using pixel data.
DECON driver can be used to drive 2 different interfaces on Exynos7:
DECON-INT(video controller) and DECON-EXT(Mixer for HDMI)
The existing FIMD driver code was used as a template to create
DECON driver. Only DECON-INT is supported as of now, and
DECON-EXT support will be added later.
The current version of the driver supports video mode displays.
Changelog v2:
- Change config name, DRM_EXYNOS_DECON to DRM_EXYNOS7_DECON.

The exynos_plane_dpms function handles enabled flag of exynos plane and
calls internal hw driver callback function for hw overlay on/off. But
it causes state disharmory problem currently and is will be obstacle to
apply atomic operation later to keep non-standard per-plane dpms state
like enabled flag.
Let's remove enabled flag, it just stop to recall internal callback
function but hw drivers can handle it properly. And call internal
callback function directly then we can remove unnecessary
exynos_plane_dpms function

exynos_plane_dpms(DRM_MODE_DPMS_ON) calls the win_enable()'s callback
from the underlying layer. However neither one of these layers implement
win_enable() - FIMD, Mixer and VIDI. Thus the call to exynos_plane_dpms()
is pointless.

The Exynos DRM driver doesn't follow the correct API when dealing with
dma_{alloc, mmap, free}_attrs functions and the
DMA_ATTR_NO_KERNEL_MAPPING attribute.
When a IOMMU is not available and the DMA_ATTR_NO_KERNEL_MAPPING is
used, the driver should use the pointer returned by dma_alloc_attr() as
a cookie.
The Exynos DRM driver directly uses the non-requested virtual kernel
address returned by the DMA mapping subsystem. This just works now
because the non-IOMMU codepath doesn't obey DMA_ATTR_NO_KERNEL_MAPPING
but we need to fix it before fixing the DMA layer.

For default graphic window, mixer_win_commit() sets display size
register as fb size. Calling setplane with smaller fb size than
mode size to default window causes distorted display result. So
this patch replaces fb size with mode size for display size from
the mixer_win_commit().

The hdmi outputs black screen only even though under the hood Xorg and
framebuffer console are fine : devices found and initialized, but
not a pixel out.
Commit 93bca243ec96 ("drm/exynos: remove struct exynos_drm_manager")
changed the call order of mixer_initialize with regards to
exynos_drm_crtc_create.
This changes breaks hdmi out on Odroid U2 (linux-next with added
Marek Szyprowski v4 hdmi patchset from linux-samsung-soc ML).
Restore the previous call ordering get hdmi to ouput proper pixels:
ie call mixer_initialize first then exynos_drm_crtc_create.

Mixed need to have hdmi clock enabled to properly perform power on/off
sequences, so add handling of this clock directly to the mixer driver.
Dependency between hdmi clock and mixer module has been observed on
Exynos4 based boards.

LP_OUTPUT_HOLD is only in MIPI_PORT_CTRL(PORT_A) even for PORT_C in case
of dual link. In the dual link implementation, the bit is correctly set
or unset for hardcoded PORT_A, but for bit update the register base value
is read by using MIPI_PORT_CTRL(port) in a loop. The second iteration will
read base value from PORT_C and program for PORT_A. Mostly in case of dual
link all other bit values should be same, but logically we should read from
PORT_A. So hardcode to read initial value from PORT_A as well.

drm/i915: Restrict GPU boost to the RCS engine
but in reality it undercovered a much older coherency bug. The issue that
boosting the GPU frequency on the BCS ring was masking was that we could
wake the CPU up after completion of a BCS batch and inspect memory prior
to the write cache being fully evicted. In order to serialise the
breadcrumb interrupt (and so ensure that the CPU's view of memory is
coherent) we need to perform a post-sync operation in the MI_FLUSH_DW.
v2: Fix all the MI_FLUSH_DW (bsd plus the duplication in execlists).
Also fix the invalidate_domains mask in gen8_emit_flush() for ring !=
VCS.

Nothing in Bspec seems to indicate that we actually needs this, and it
looks like can't work since by this point the pipe is off and so
vblanks won't really happen any more.
Note that Bspec mentions that it takes a vblank for this bit to
change, but _only_ when enabling.
Dropping this code quenches an annoying backtrace introduced by the
more anal checking since

drm/i915: Use generic vblank wait

the shortcomings of the IBX transcoder select workaround implementation

As per the specififcation, the SB_DevFn is the PCI_DEVFN of the target
device and not the source. So PCI_DEVFN(2,0) is not correct. Further the
port ID should be enough to identify devices unless they are MFD. The
SB_DevFn was intended to remove ambiguity in case of these MFD devices.
For non MFD devices the recommendation for the target device IP was to
ignore these fields, but not all of them followed the recommendation.
Some like CCK ignore these fields and hence PCI_DEVFN(2, 0) works and so
does PCI_DEVFN(0, 0) as it works for DPIO. The issue came to light because
of GPIONC which was not getting programmed correctly with PCI_DEVFN(2, 0).
It turned out that this did not follow the recommendation and expected 0
in this field.
In general the recommendation is to use SB_DevFn as PCI_DEVFN(0, 0) for
all devices except target PCI devices.

It's possible for invalidate_range_start mmu notifier callback to race

obtaining the spinlock in invalidate_range_start we're hitting null

Flushing out my drm-misc queue with a few oddball things all over.

drm: Use static attribute groups for managing connector sysfs entries

Instead of manual calls of device_create_file() and
device_remove_file(), assign the static attribute groups to the device
with device_create_with_groups(). The conditionally built sysfs
entries are handled via is_visible callback.
This simplifies the code and also avoids the possible races.

drm: Add multi buffer plane pixel formats
which hasn't seen a lot of review really. The problem is that it's not
a real pixel format, but just a different way to lay out NV12 pixels
in macroblocks, i.e. a tiling format.
The new way of doing this is with the soon-to-be-merged fb modifiers.
This was brough up in some long irc discussion around the entire
topic, as an example of where things have gone wrong. Luckily we can
correct the mistake:
- The kms side support for NV12MT is all dead code because
format_check in drm_crtc.c never accepted NV12MT.
- The gem side for the gsc support doesn't look better: The code
forgets to set the pixel format and makes a big mess with the tiling
mode bits, inadvertedly setting them all.
Conclusion: This never really worked (at least not in upstream) and
hence we can safely correct our mistake here.

Currently when a mode is rejected the reason is printed as a raw number.
Having to manually decode that to a enum drm_mode_status value is
tiresome. Have the code do the decoding instead and print the result
in a human readable format.
Just having an array of strings indexed with the mode status doesn't
work since the enum includes negative values. So we offset the status
by +3 which makes all the indexes non-negative. Also add a bit of
paranoia into the code to catch out of bounds accesses in case
someone adds more enum values but forgets to update the code.

The .enable_vblank() operation is only called when vblank interrupts are
disabled, but no similar check exists when disabling vblank interrupts.
This leads to .disable_vblank() being called with vblank interrupts
already disabled and the device possibly runtime suspended. As the
operation is called with a spinlock held drivers can't runtime resume
the device there and thus must avoid touching device registers in that
case, requiring vblank refcounting.
As the DRM core tracks whether vblank interrupts are enabled just skip
the .disable_vblank() call when the interrupts are already disabled.
