Subject: [PATCH v3 2/5] usb: musb: dsps: Call usb_phy(_shutdown/_init) during musb_platform_reset()
Date: Tue, 13 May 2014 14:01:42 +0530 [thread overview]
Message-ID: <1399969905-3509-3-git-send-email-george.cherian@ti.com> (raw)
In-Reply-To: <1399969905-3509-1-git-send-email-george.cherian@ti.com>
For DSPS platform usb_phy_vbus(_off/_on) are NOPs.
So during musb_platform_reset() call usb_phy(_shutdown/_init)
