+Subject: [PATCH 04/10] omap3: beaglexm: fix EHCI power up GPIO dir
+
+EHCI enable power pin is inverted (active high) in comparison
+to vanilla beagle which is active low. Handle this case conditionally.
+
+Without this fix, Beagle XM 4 port EHCI will not function and no
+networking will be available
