Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=15155f7c0e302f9cbf9f0c00cfa4812905a300e7

--------------------------------

commit 5c294de3 upstream.

This reverts commit 6000b8d9.

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
34c7ed72 ("usb: core: phy: add support for PHY calibration") and
a0a46556 ("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.
