Allow extcon device, found by name, to provide DR status for USB.
This is needed, for example, in case of Intel Merrifield platform,
where the Intel Basin Cove PMIC provides an extcon device to communicate
the detected role.
Note, that the "linux,extcon-name" property name is only for kernel
internal use by X86/ACPI platform code and as such is not documented
in the device tree bindings.

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.
