+From dbcbcdd001c5943adbb18db3b8f0dafc405559eb Mon Sep 17 00:00:00 2001
+From: Hauke Mehrtens <hauke@hauke-m.de>
+Date: Tue, 13 Mar 2012 01:04:53 +0100
+Subject: [PATCH 03/47] USB: use generic platform driver on ath79
+
+The ath79 usb driver doesn't do anything special and is now converted
+to the generic ehci and ohci driver.
+This was tested on a TP-Link TL-WR1043ND (AR9132)
