The AM62x and AM62Px SoCs feature 2 OLDI TXes each, which makes it possible to connect them in dual-link or cloned single-link OLDI display modes. The current OLDI support in tidss_dispc.c can only support for a single OLDI TX, connected to a VP and doesn't really support configuration of OLDIs in the other modes. The current OLDI support in tidss_dispc.c also works on the principle that the OLDI output can only be served by one, and only one, DSS video-port. This isn't the case in the AM62Px SoC, where there are 2 DSS controllers present that share the OLDI TXes. Having their own devicetree and their own bridge entity will help support the various display modes and sharing possiblilities of the OLDI hardware. For all these reasons, add support for the OLDI TXes as DRM bridges.

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.
