If anyone has any objections, please let me know. ------------------ From: Mathias Kresin commit 3223a5a7d3a606dcb7d9190a788b9544a45441ee upstream. On Danube and AR9 the USB core is connected though a AHB bus to the main system cross bar, hence we need to enable the gating clock of the AHB Bus as well to make the USB controller work.
