The backtrace below shows that while we tear down a branch device,
when we remove the connector, we can attempt to disable MST on the
port we are tearing down, since the port is going away, there it
has a refcount of 0 already, so the validated ref lookup is trying
to kref_get a

A tile group is an identifier shared by a single monitor,
DisplayID topology has 8 bytes we can use for this, just
use those for now until something else comes up in the
future. We assign these to an idr and use the idr to
tell userspace what connectors are in the same tile grou

This adds fbdev/con support for tiled monitors, so that we
only set a mode on the correct half of the monitor, or
span the two halves if needed.

Logical ports are never going to have EDID changes,
they are used for the internal ports on MST monitors.
We cache the EDIDs from these to save time at MST probe.

These are a repost of the tile group patches, with some r-b's added,
and few things fixed.
One line in patch 3 moved to its correct home in patch 5 so
things make more sense.

This creates a tile group from DisplayID block, and
stores the pieces of parsed info from the DisplayID block
into the connector.
v2: add missing signoff, add new connector bits to docs.

This takes the tiling info from the connector and
exposes it to userspace, as a blob object in a
connector property.
The contents of the blob is ABI.
v2: add property + function documentation.
v3: move property setup from previous patch.

Thanks, Chris. That works a charm! and gets me exactly where I want to

So here's my atomic series, finally all debugged&reviewed. Sean Paul has
