Subject: [PATCH 01/10] usb: phy: Fix initial state for twl6030
Date: Thu, 28 Apr 2016 10:33:11 -0700 [thread overview]
Message-ID: <1461864800-29979-2-git-send-email-tony@atomide.com> (raw)
In-Reply-To: <1461864800-29979-1-git-send-email-tony-4v6yS6AI5VpBDgjK7y7TUQ@public.gmane.org>
We need to check the state for the PHY with delayed_work so
as otherwise MUSB will get confused and idles immediately.
