From 82ae68be70a666618e080c56aa57af41859469b8 Mon Sep 17 00:00:00 2001 From: Mathias Kresin Date: Sat, 20 Jan 2018 14:38:40 +0100 Subject: [PATCH] lantiq: kernel 4.14: fix usb On danube the USB0 registers are at 1e101000 similar to all other lantiq SoCs. On Danube and AR9 the USB core is connected to the AHB bus, hence we need to enable the AHB Bus as well.
