Subject: [PATCH v2 06/10] usb: xhci: Enable runtime pm in xhci-plat
Date: Sat, 02 Mar 2013 18:53:07 +0530	[thread overview]
Message-ID: <1362230590-20960-7-git-send-email-gautam.vivek@samsung.com> (raw)
In-Reply-To: <1362230590-20960-1-git-send-email-gautam.vivek@samsung.com>

By enabling runtime pm in this driver allows users of
xhci-plat to enter into runtime pm. This is not full
runtime pm support (AKA xhci-plat doesn't actually power
anything off when in runtime suspend mode) but,
just basic enablement.
