Subject: [RFC PATCH 5/6] ARM: dts: omap3beagle-xm: Add idle state pins for USB host
Date: Wed, 19 Jun 2013 17:05:52 +0300 [thread overview]
Message-ID: <1371650753-11452-6-git-send-email-rogerq@ti.com> (raw)
In-Reply-To: <1371650753-11452-1-git-send-email-rogerq@ti.com>
Add the Idle state pins for USB host and enable WAKEUP on
DIR, DAT0-3, so that the PHY can wakeup the OMAP SoC from
sleep on any USB activity (e.g. remote wakeup or connect/disconnect).
