In short, we have three kinds of role switches: - Based on SoC: ID and VBUS - Based on external connnctor, eg, Type-C or GPIO Connector - Based on user choices through sysfs Since HW handling and usb-role-switch handling are at different places, we do not need role_override any more, and this flag could not judge external connector case well. With role_override deleted, We use cdns3_hw_role_switch for the 1st use case, and usb-role-switch for the 2nd and 3rd cases.

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.
