Subject: [PATCH v4 12/13] phy: usb: USB driver is crashing during S3 resume on 7216
Date: Fri, 3 Jan 2020 13:18:10 -0500 [thread overview]
Message-ID: <20200103181811.22939-13-alcooperx@gmail.com> (raw)
In-Reply-To: <20200103181811.22939-1-alcooperx@gmail.com>
This is a result of the USB 2.0 clocks not being disabled/enabled
during suspend/resume on XHCI only systems.
