Subject: lantiq: fix PCI problems on ARV4510PW
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=eddc327c7ca388d953fd74260ac9b429d57d3da8;p=openwrt%2Fstaging%2Fluka.git

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.
