The TI HD3SS3220 Type-C controller supports configuring its role preference when operating as a dual-role port through the SOURCE_PREF field of the General Control Register. The previous driver behavior was to set the role preference based on the dr_set typec_operation. However, the controller does not support swapping the data role on an active connection due to its lack of Power Delivery support. Remove previous dr_set typec_operation, and support setting the role preference based on the corresponding fwnode property, as well as the try_role typec_operation.

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 reStructuredText 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.
