Subject: ath79: update DTS for TP-Link WDR3600/WDR4300 v1
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=32144ba275d163ce6e7d93546ab4414f03f508fb;p=openwrt%2Fstaging%2Fansuel.git

ath79: update DTS for TP-Link WDR3600/WDR4300 v1

This replaces gpio-export by gpio-hogs and switches buttons
to interrupt-driven gpio-keys.
