Subject: mac80211: convert UniFi Outdoor+ HSR support to OF
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=0c499f6068176c1139d5c6b7d89f454b03383453;p=openwrt%2Fstaging%2Fldir.git

mac80211: convert UniFi Outdoor+ HSR support to OF

Enable support for the Ubiquiti UniFi Outdoor+ RF filter via
device-tree. The old way of using platform data is not required anymore,
as it was only used on the now removed ar71xx target.
