Subject: ath79: add support for TP-Link TL-WR941ND v5
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=e22ca21daab6d5be87b2b005b5a9440629730169;p=openwrt%2Fstaging%2Fthess.git

ath79: add support for TP-Link TL-WR941ND v5

Specifications:
- SoC: ar9341
- RAM: 32M
- Flash: 4M
- Ethernet: 5x FE ports
- WiFi: ar9341-wmac

Flash instruction:
Upload generated factory firmware on vendor's web interface.

This device is very similar to the TL-WR841N v8, only two LED GPIOs are
different.
Buttons configuration is similar to TL-WR842ND v2 but both buttons are
active low.
