Pull more drm updates from Dave Airlie:
"Fixes/cleanups for rc1, non-desktop flags for VR
- remove the MSM dt-bindings file Rob managed to push in the previous
pull.
- add a property/edid quirk to denote HMD devices, I had these
hanging around for a few weeks and Keith had done some work on
them, they are fairly self contained and small, and only affect
people using HTC Vive VR headsets so far.
- amdgpu, tegra, tilcdc, fsl fixes
- some imx-drm cleanups I missed, these seemed pretty small, and no
reason to hold off.
I have one TTM regression fix (fixes bochs-vga in qemu) sitting
locally awaiting review I'll probably send that in a separate pull
request tomorrow"

We don't want fbcon to get used on non-desktop dislays,
don't pass them as enabled connectors to the fb helper setup.
This prevents my HMD from getting disorted fbcon, and from
affecting other displays console.

This adds the infrastructure needed to quirk displays
using edid and to mark them a non-desktop.
A non-desktop display is one which shouldn't normally be included
as a part of a desktop environment.
This is meant to cover head mounted devices like HTC Vive.

This patch removes DRM_TILCDC_SLAVE_COMPAT option for supporting the
obsolete "ti,tilcdc,slave" device tree binding. The new of_graph based
binding - that is widely used in other drm driver too - has been
supported since Linux v4.2. Maintaining the the backwards dts
conversion code in the DRM_TILCDC_SLAVE_COMPAT has become a nuisance
for the device/of development so the we decided to drop it after Linux
v4.14, the 2017 LTS.

Use drm_*_get() and drm_*_put() helpers instead of drm_*_reference()
and drm_*_unreference() helpers.
drm_*_reference() and drm_*_unreference() functions are just
compatibility alias for drm_*_get() and drm_*_put() and should not be
used by new code. So convert all users of compatibility functions to
use the new APIs.

drm/tegra: Fixes for v4.15-rc1
This includes an update to the SOR pad clock programming needed because
of some changes that went in through the clock tree.
* tag 'drm/tegra/for-4.15-rc1-fixes' of git://anongit.freedesktop.org/tegra/linux:
drm/tegra: sor: Reimplement pad clock

The current implementation of the pad clock isn't quite correct. This
has the side-effect of being incompatible with the implementation for
Tegra186 (provided by the BPMP) and therefore would require a massive
change to the driver to cope with the differences. Instead, simply do
what Tegra186 does and add some code to fallback to the old behaviour
for existing device trees.

Disabling the pixel clock in suspend leads to a warning due to

Since commit 4a97a3da420b ("drm: Don't update property values for atomic
drivers") atomic drivers must not update property values as properties
are read from the state instead. To catch remaining users, the
drm_object_property_set_value() function now throws a warning when
called by atomic drivers on non-immutable properties, and we hit that
warning when creating connectors.
The easy fix is to just remove the drm_object_property_set_value() as it
is used here to set the initial value of the connector's DPMS property
to OFF. The DPMS property applies on top of the connector's state crtc
pointer (initialized to NULL) that is the main connector on/off control,
and should thus default to ON.

The index to vddci_buf is using profile->ucElbVDDC_Num rather
than profile->ucElbVDDCI_Num; this looks like a copy-n-paste
error from previous code for the vddc_buf array and I'm pretty
sure this is incorrect. Fix this by using the correct variable.

Pull amdgpu DC display code for Vega from Dave Airlie:
"This is the pull request for the AMD DC (display code) layer which is
a requirement to program the display engines on the new Vega and Raven
based GPUs. It also contains support for all amdgpu supported GPUs
(CIK, VI, Polaris), which has to be enabled. It is also a kms atomic
modesetting compatible driver (unlike the current in-tree display
code).
I've kept it separate from drm-next because it may have some things
that cause you to reject it.
Background story:
AMD have an internal team creating a shared OS codebase for display at
hw bring up time using information from their hardware teams. This
process doesn't lead to the most Linux friendly/looking code but we
have worked together on cleaning a lot of it up and dealing with
sparse/smatch/checkpatch, and having their team internally adhere to
Linux coding standards.
This tree is a complete history rebased since they started opening it,
we decided not to squash it down as the history may have some value.
Some of the commits therefore might not reach kernel standards, and we
are steadily training people in AMD to better write commit msgs.
There is a major bunch of generated bandwidth calculation and
verification code that comes from their hardware team. On Vega and
before this is float calculations, on Raven (DCN10) this is double
based. They do the required things to do FP in the kernel, and I could
understand this might raise some issues. Rewriting the bandwidth would
be a major undertaken in reverification, it's non-trivial to work out
if a display can handle the complete set of mode information thrown at
it.
Future story:
There is a TODO list with this, and it address most of the remaining
things that would be nice to refine/remove. The DCN10 code is still
under development internally and they push out a lot of patches quite
regularly and are supporting this code base with their display team. I
think we've reached the point where keeping it out of tree is going to
motivate distributions to start carrying the code, so I'd prefer we
get it in tree. I think this code is slightly better than STAGING
quality but not massively so, I'd really like to see that float/double
magic gone and fixed point used, but AMD don't seem to think the
accuracy and revalidation of the code is worth the effort"

This is a followup to the following revert:
Rex Zhu Revert "drm/amd/display: Match actual state during S3
resume."
Three things needed to be addressed:
1. Potential memory leak on dc_state creation in atomic_check during
s3 resume
2. Warnings are now seen in dmesg during S3 resume
3. Since dc_state is now created in atomic_check, what the reverted
patch was addressing needs to be reevaluated.
This change addresses the above:
1. Since the suspend procedure calls drm_atomic_state_clear, our hook
for releasing the dc_state is called. This frees it before
atomic_check creates it during resume. The leak does not occur.
2. The dc_crtc/plane_state references kept by the atomic states need to
be released before calling atomic_check, which warns if they are
non-null. This is because atomic_check is responsible for creating
the dc_*_states. This is a special case for S3 resume, since the
atomic state duplication that occurs during suspend also copies a
reference to the dc_*_states.
3. See 2. comments are also updated to reflect this.
