Some platforms (e.g. RK3399 BOX board) otg port connector
interface is not standard, that is a Type-A connector with
vbus always powered on, looks like to work as host mode,
however, the otg port still need to support DRD mode.
In the current code, if otg vbus is always powered on, it
will cause USB2 PHY to detect a floating charger in error
case and power off USB2 PHY. This patch adds a new property
"rockchip,vbus-always-on" to fix this issue. With this patch,
we handle this case as otg host only mode, and avoid to do
charger detection and power off USB2 PHY.

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.
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.
