+Subject: Revert "usb: dwc3: disable USB core PHY management"
+
+From: Johan Hovold <johan+linaro@kernel.org>
+
+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
+34c7ed72f4f0 ("usb: core: phy: add support for PHY calibration") and
+a0a465569b45 ("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.
