From eddc327c7ca388d953fd74260ac9b429d57d3da8 Mon Sep 17 00:00:00 2001 From: Luka Perkov Date: Sat, 15 Feb 2014 22:54:32 +0000 Subject: [PATCH] lantiq: fix PCI problems on ARV4510PW Some ARV4510PW units seem to have unstable PCI due to missing pull-up resistors. This patch makes sure that the GPIO lines are driven properly.
