This board features multiple USB connectors: * One Type-C connector with Power Delivery and Alt. Modes; * One MicroUSB connector, also used for bootloader SW download; * One USB through the RaspberryPi-compatible pins header. Add configuration for the MTU3 controllers providing OTG support with role switching both on the MicroUSB port, RPi pins header, and the Type-C port found on this board. Moreover, add the Richtek RT1715 Type-C Power Delivery Controller which manages current source/sink, linked to the iTE IT5205 Type-C Alternate Mode Passive Mux, handling both mode switching between USB (up to 3.1 Gen2 10Gbps) and DisplayPort (four lanes, DP1.4, op to 8.1Gbps) and plug orientation switching. All USB ports reside on different controller instances, and all of them support host or gadget and can be configured as desired at runtime.

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.
