The TC358767/TC358867/TC9595 are all capable of operating in multiple modes, DPI-to-(e)DP, DSI-to-(e)DP, DSI-to-DPI. Only the first mode is currently supported. It is possible to find out the mode in which the bridge should be operated by testing connected endpoints in DT. Port allocation: port@0 - DSI input port@1 - DPI input/output port@2 - eDP output Possible connections: DPI -> port@1 -> port@2 -> eDP :: [port@0 is not connected] DSI -> port@0 -> port@2 -> eDP :: [port@1 is not connected] DSI -> port@0 -> port@1 -> DPI :: [port@2 is not connected] Add function to determine the bridge mode based on connected endpoints.

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.
