Subject: [PATCH 10/11] usb: musb: dsps: get the PHY using phandle api
Date: Thu, 12 Jul 2012 15:23:33 +0530 [thread overview]
Message-ID: <1342086814-32181-11-git-send-email-ajay.gupta@ti.com> (raw)
In-Reply-To: <1342086814-32181-1-git-send-email-ajay.gupta-l0cyMroinI0@public.gmane.org>
AM33xx has two PHY of same type used by each musb controller so
use phandle of phy nodes to get the phy pointer.
