OK. In case you are eager to test, please use the series [1] on l-o on top of Benoit's
for_3.11/_dts branch and then the $subject series with the updated patch 5 below [2].
[1] - [PATCH v5 0/2] ARM: dts: Add USB host support for Beagle-xm
[2] - Updated Patch 5

Subject: [PATCH] ARM: dts: omap3beagle-xm: Add idle state pins for USB host
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
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).
