Subject: [PATCH v3 12/13] phy: usb: USB driver is crashing during S3 resume on 7216
Date:   Tue, 10 Dec 2019 08:21:31 -0500
Message-Id: <20191210132132.41509-13-alcooperx@gmail.com>
In-Reply-To: <20191210132132.41509-1-alcooperx@gmail.com>
References: <20191210132132.41509-1-alcooperx@gmail.com>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

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