From: John Crispin Date: Mon, 15 Sep 2014 10:19:38 +0000 (+0000) Subject: ar71xx: add qihoo 360 c301 router support X-Git-Tag: reboot~5939 X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=7dbbdfb61f99a765ff02d40daa1d63c769df41ef;p=openwrt%2Fstaging%2Fxback.git ar71xx: add qihoo 360 c301 router support Qihoo 360 C301 is a dual band wireless router supports 802.11n and 802.11ac. Its chipset is AR9344 + AR9882 with two 16MB flashes. This patch adds its initial support. v2: * use mtd_get_mac_ascii to fetch MAC address for ath10k. * use ath79_register_pci to initialize AR9882.
