+Subject: [PATCH] dt-bindings: leds: Add FUNCTION defines for per-band WLANs
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Most wireless routers and access points can operate in multiple bands
+simultaneously. Vendors often equip their devices with per-band LEDs.
+
+Add defines for those very common functions to allow cleaner & clearer
+bindings.

+Subject: [PATCH] dt-bindings: leds: Add LED_FUNCTION_WAN_ONLINE for Internet
+ access
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+It's common for routers to have LED indicating link on the WAN port.
+
+Some devices however have an extra LED that's meant to be used if WAN
+connection is actually "online" (there is Internet access available).
+
+It was suggested to add #define for such use case.
