Subject: [PATCHv2 1/7] usb: phy: twl4030-usb: don't enable PHY during init
Date: Sun, 17 Mar 2013 20:23:21 +0200	[thread overview]
Message-ID: <1363544607-17634-2-git-send-email-notasas@gmail.com> (raw)
In-Reply-To: <1363544607-17634-1-git-send-email-notasas-Re5JQEeQqe8AvxtiuMwx3w@public.gmane.org>

There is no need to do it, otg.set_suspend(false) (which itself
comes from runtime_pm OMAP glue calls) will enable it later anyway.
This used to be the place where things were enabled if booted with
cable connected before runtime_pm conversion, but now can be dropped.
