Subject: [PATCH v5 3/6] usb: musb: dsps: Call usb_phy(_shutdown/_init) during musb_platform_reset()
Date: Thu, 22 May 2014 11:59:38 +0530	[thread overview]
Message-ID: <1400740181-31213-4-git-send-email-george.cherian@ti.com> (raw)
In-Reply-To: <1400740181-31213-1-git-send-email-george.cherian-l0cyMroinI0@public.gmane.org>

For DSPS platform usb_phy_vbus(_off/_on) are NOPs.
So during musb_platform_reset() call usb_phy(_shutdown/_init)
