[PATCH v2 12/13] phy: usb: USB driver is crashing during S3 resume on 7216

From: Al Cooper <alcooperx@gmail.com>
Date: 2019-11-15 18:44:04
Also in: linux-devicetree, lkml
Subsystem: broadcom brcmstb usb2 and usb3 phy driver, generic phy framework, the rest · Maintainers: Justin Chen, Al Cooper, Vinod Koul, Linus Torvalds

This is a result of the USB 2.0 clocks not being disabled/enabled
during suspend/resume on XHCI only systems.
