At the moment, the dtsi will force the dr_mode to host. This is problematic because it will always turn on the Vbus voltage regardless if the port is host or device. This might lead to a "shortcut" between the two USB endpoints because both might have their Vbus supplies enabled. Therefore, the default should be "otg" for any ports which aren't host only (from a SoC point of view) and have a user of the dtsi file overwrite that explicitly. Move the 'dr_mode = "host";' into the board dts. Now that the dtsi doesn't set the dr_mode anymore, we can also drop the 'dr_mode = "otg";' in the board dts because that is the default value if dr_mode is not set.

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.
