Subject: [PATCH v3 07/10] usb: chipidea: imx: Enable runtime pm support for imx6q
Date: Tue, 5 Nov 2013 09:55:22 +0800 [thread overview]
Message-ID: <1383616525-10769-8-git-send-email-peter.chen@freescale.com> (raw)
In-Reply-To: <1383616525-10769-1-git-send-email-peter.chen@freescale.com>
Currently, only imx6q adds wakeup logic, so only enable
runtime pm for imx6q.
