From 6c1adb3eecff7e86f7396e1aa443ee1ce947d9ec Mon Sep 17 00:00:00 2001 From: Felix Fietkau Date: Fri, 11 Sep 2015 16:35:46 +0000 Subject: [PATCH] lantiq: Use the BAR0 base address in the ath PCI fixup code Fixes support for AR9287 on TP-Link TD-W8980 and possibly other devices which have an ath wifi chip at a PCI address other than 0xb8000000 (TD-W8980 for example has it's wifi chip at 0xbc000000).
