The Orange Pi PC, PC Plus, and Plus 2E all have a USB OTG port that can be used in both powered host mode and peripheral mode. When in peripheral mode, the port does not power the board. There is no VBUS sensing on the port. All three boards have all related pins routed the same way. The device tree file for the Orange Pi Plus 2E is based on the Orange Pi PC Plus, which itself is based on the Orange Pi PC. Changes to the base Orange Pi PC device tree file affects all 3 boards. This patch adds the regulator controlling VBUS on the OTG port, the GPIO for the ID detect pin, and enables the USB OTG and host controllers.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. 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.
