Subject: [PATCH v8 09/12] usb: phy: Add set_wakeup API
Date: Tue, 24 Dec 2013 11:58:53 +0800	[thread overview]
Message-ID: <1387857536-4996-10-git-send-email-peter.chen@freescale.com> (raw)
In-Reply-To: <1387857536-4996-1-git-send-email-peter.chen@freescale.com>

This API is used to set wakeup enable at PHY registers, in that
case, the PHY can be waken up from suspend due to external events,
like vbus change, dp/dm change and id change.
