Subject: [PATCH v1 6/6] usb: dwc3: core: Notify USB3 PHY as well for DRD modes
Date: Fri, 21 Jul 2017 16:32:01 +0530 [thread overview]
Message-ID: <1500634921-25914-7-git-send-email-mgautam@codeaurora.org> (raw)
In-Reply-To: <1500634921-25914-1-git-send-email-mgautam@codeaurora.org>
Driver currently notifies only USB3 PHY for mode change.
Extend this to USB3 PHY so that driver based on the mode
can release system resources - clocks, regulators etc.
and can even turn off PHY during runtime suspend.
