Linux kernel source tree
c0ff6c6e4c
Each SDVO device can have up to three sets of DDC pins. Currently we just register a single i2c_adapter for the entire SDVO device and semi-randomly pick the "correct" set of DDC pins during intel_sdvo_tmds_sink_detect(). This doesn't make any real sense especially if we have multiple outputs each with their own dedicated DDC bus. Let's clean up this mess and register a dedicated i2c_adapter for each of the possible pin pairs. Each output (ie. connector) can then pick the correct i2c_adapter to use for its DDC bus. And we can just switch over to drm_connector_init_with_ddc() to take care of the connector->ddc association, which also populates the "ddc" sysfs symlink as a bonus. And now that things are based on the actual connector we can also nuke the sketchy sdvo->controller_output thing.

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.
