Using a (single) DSI display with MCDE currently results in
two "connected" connectors:
Connector: DSI-1
id : 34
encoder id : 0
conn : connected
size : 0x0 (mm)
count_modes : 0
count_props : 5
props : 1 2 5 6 4
count_encoders : 1
encoders : 33
Connector: DSI-2
id : 35
encoder id : 33
conn : connected
size : 53x89 (mm)
count_modes : 1
count_props : 5
props : 1 2 5 6 4
count_encoders : 1
encoders : 33
Mode: "480x800" 480x800 60
Although both show up as connected, the first one does not have
any size and no available modes. This confuses userspace tools
(e.g. kmscube) who look for available modes for the first connector.
The reason for the duplicated connector is that mcde_dsi.c and the
DRM panel bridge helper both set up a DSI connector, with more or less
the same code. The connector set up by the DRM panel bridge is the
one that is correctly set up in the example above.
Therefore we can just remove the connector setup from mcde_dsi.c
and let the DRM core handle all the hard work.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
