Heikki Krogerus ae4ba35d36 usb: typec: Allow power role swapping even without USB PD
Even though originally the USB Type-C Specification did not
describe the steps for power role swapping without USB PD
contract in place, it did not actually mean power role swap
without USB PD was not allowed. The USB Type-C Specification
did not clearly separate the data and power roles until in
the release 1.2 which is why there also were no clear steps
for the scenario where only the power role was swapped
without USB PD contract before that.

Since in the latest version of the specification the power
role swap without USB PD is now clearly mentioned as allowed
operation, removing the check that prevented power role swap
without USB PD support.

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.
