Johan Hovold 56607f0bfc Revert "usb: dwc3: disable USB core PHY management"
commit 5c294de36e7fb3e0cba0c4e1ef9a5f57bc080d0f upstream.

This reverts commit 6000b8d900cd5f52fbcd0776d0cc396e88c8c2ea.

The offending commit disabled the USB core PHY management as the dwc3
already manages the PHYs in question.

Unfortunately some platforms have started relying on having USB core
also controlling the PHY and this is specifically currently needed on
some Exynos platforms for PHY calibration or connected device may fail
to enumerate.

The PHY calibration was previously handled in the dwc3 driver, but to
work around some issues related to how the dwc3 driver interacts with
xhci (e.g. using multiple drivers) this was moved to USB core by commits
34c7ed72f4 ("usb: core: phy: add support for PHY calibration") and
a0a465569b ("usb: dwc3: remove generic PHY calibrate() calls").

The same PHY obviously should not be controlled from two different
places, which for example do no agree on the PHY mode or power state
during suspend, but as the offending patch was backported to stable,
let's revert it for now.

README

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.
