Subject: [PATCH v2 04/10] usb: dwc3: Add runtime power management callbacks
Date: Sat, 02 Mar 2013 18:53:05 +0530	[thread overview]
Message-ID: <1362230590-20960-5-git-send-email-gautam.vivek@samsung.com> (raw)
In-Reply-To: <1362230590-20960-1-git-send-email-gautam.vivek@samsung.com>

Right now it doesn't handle full runtime suspend/resume
functionality. However it allows to handle PHYs' sleep
and wakeup across runtime suspend/resume.
