+Subject: ar71xx: add kernel support for the TL-WDR3500 board
|
|
|
+
|
|
|
+WDR3500 is similar to WDR3600 except it doesn't have gigabit ethernet,
|
|
|
+and has only 1 USB port.
|
|
|
+
|
|
|
+Pending issues:
|
|
|
+
|
|
|
+ * Leds are not working at all (except power and wlan_5g)
|
|
|
+ * LAN switch ethernet ports are reversed with respect to case label.
|
|
|
+
|
|
|
+ [Label] -> soft device
|
|
|
+ [LAN1] -> eth0.4
|
|
|
+ [LAN2] -> eth0.3
|
|
|
+ [LAN3] -> eth0.2
|
|
|
+ [LAN4] -> eth0.1
|
|
|
+
|
|
|
+Based on http://patchwork.openwrt.org/patch/3208/
|
|
|
+
|
|
|
+Thanks-to: Paul Fertser <fercerpav@gmail.com>
