This allows us to ditch a ton of ugly #ifdefs from a bunch of drm modeset
drivers.

v2: Make the dummy function actually return a sane value, spotted by
Ville.

v3: Because the patch is still in limbo there's no more drivers to
convert, noticed by Emil.

v4: Rebase once more, because hooray. I'll just go ahead an apply this
one later on to drm-misc.

This goes all the way back to the original KMS commit aeons ago

commit f453ba04
Author: Dave Airlie <airlied@redhat.com>

    DRM: add mode setting support

But it seems to be completely unused. Only i915 and nouveau even
register these properties, and the corresponding DDX don't even look
at them. Also the sysfs files are read-only, so not useful to
configure anything.

I suspect that this was added with the goal to have read-only access
to all properties in sysfs, but we never followed through on that.
Also, that should be done in a more generic fashion.

Since it would be real work to fix up the locking (with atomic we're
now chasing pointers when reading properties) and it seems unused lets
just nuke this all. It's easier. Of course we'll keep the properties
themselves, those are still exposed through the KMS ioctls.

It tries to do fancy things with excluding agp support if ttm is
built-in, but agp isn't. Instead just express this depency like drm
does and use CONFIG_AGP everywhere.

Also use the neat Makefile magic to make the entire ttm_agp_backend
file optional.

v2: Use IS_ENABLED(CONFIG_AGP) as suggested by Ville

v3: Review from Emil.

v4: Actually get it right as spotted by 0-day.

Current name is a bit misleading because what that helper function

This all has nothing to do with hotplugging so let's name things
properly.

And while at it remove potentially dangerous locking around
drm_connector_unregister() in rcar_du_remove() as mentioned
in kerneldoc for drm_connector_unregister_all().

Drivers, especially i915.ko, can fail during the initial migration of a
dma-buf for CPU access. However, the error code from the driver was not
being propagated back to ioctl and so userspace was blissfully ignorant
of the failure. Rendering corruption ensues.

Whilst fixing the ioctl to return the error code from
dma_buf_start_cpu_access(), also do the same for
dma_buf_end_cpu_access().  For most drivers, dma_buf_end_cpu_access()
cannot fail. i915.ko however, as most drivers would, wants to avoid being
uninterruptible (as would be required to guarrantee no failure when
flushing the buffer to the device). As userspace already has to handle
errors from the SYNC_IOCTL, take advantage of this to be able to restart
the syscall across signals.

This fixes a coherency issue for i915.ko as well as reducing the
uninterruptible hold upon its BKL, the struct_mutex.

SADs may span multiple CEA audio data blocks in the EDID.

CEA-861-E says:
"The order of the Data Blocks is not constrained. It is also possible
to have more than one of a specific type of data block if necessary to
include all of the descriptors needed to describe the sink’s capabilities."

Each audio data block can carry up to 10 SADs, whereas the ELD SAD limit
is 15 according to HDA 1.0a spec. So we should support at least two data
blocks. And apparently some devices take a more liberal interpretation
and stuff only one SAD per data block even when they would fit into one.

So let's try to extract all the SADs we can fit into the ELD even when
they span multiple data blocks.

While at it, toss in a comment to explain the 13 byte monitor name
string limit which confused me at first.

Patch based on a previous series by Shashank Sharma.

This introduces optional properties to enable color correction at the
pipe level. It relies on 3 transformations applied to every pixels
displayed. First a lookup into a degamma table, then a multiplication
of the rgb components by a 3x3 matrix and finally another lookup into
a gamma table.

The following properties can be added to a pipe :
  - DEGAMMA_LUT : blob containing degamma LUT
  - DEGAMMA_LUT_SIZE : number of elements in DEGAMMA_LUT
  - CTM : transformation matrix applied after the degamma LUT
  - GAMMA_LUT : blob containing gamma LUT
  - GAMMA_LUT_SIZE : number of elements in GAMMA_LUT

DEGAMMA_LUT_SIZE and GAMMA_LUT_SIZE are read only properties, set by
the driver to tell userspace applications what sizes should be the
lookup tables in DEGAMMA_LUT and GAMMA_LUT.

A helper is also provided so legacy gamma correction is redirected
through these new properties.

v2: Register LUT size properties as range

v3: Fix round in drm_color_lut_get_value() helper
    More docs on how degamma/gamma properties are used

v4: Update contributors

v5: Rename CTM_MATRIX property to CTM (Doh!)
    Add legacy gamma_set atomic helper
    Describe CTM/LUT acronyms in the kernel doc

v6: Fix missing blob unref in drm_atomic_helper_crtc_reset

Instead of failing with -EINVAL when conflicting encoders are found,
the legacy set_config will disable other connectors when encoders
conflict.

With the previous commit this becomes a lot easier to implement.
set_config only adds connectors to the state that are modified,
and because of the previous commit that calls add_affected_connectors
only on set->crtc it means any connector not part of the modeset can
be stolen from. We disable the connector in that case, and possibly
the crtc if required.

Atomic modeset itself still doesn't allow encoder stealing, the results
would be too unpredictable.

There's no need to have a separate function to get the crtc

stealing the encoder.

drm_for_each_connector already checks for connection_mutex, so
use that macro now.

Minor cleanup, connector and connector_state are always non-NULL here.

With the addition of crtc_state->connector_mask other connectors from
different crtc's aren't needed any more to determine if a crtc has
connectors, so only call add_affected_connectors on the target crtc.
This allows a cleanup to first remove all current connectors, then
add all set->connectors to the target crtc.
