+Subject: [PATCH] MIPS: BCM47XX: Add support for Netgear WNR1000 V3
+
+This adds support for detecting this model board and registers some LEDs
+and buttons.
+
+There are two uncommon things regarding this device:
+1) It can use two different "board_id" ID values.
+   Unit I have uses "U12H139T00_NETGEAR" value. This magic is also used
+   in firmware file header. There are two reports (one from an OpenWrt
+   user) of a different "U12H139T50_NETGEAR" magic though.
+2) Power LEDs share GPIOs with buttons.
+   Amber one seems to share GPIO 2 with WPS button and green one seems
+   to share GPIO 3 with reset button. It remains unknown how to support
+   them and handle buttons at the same time. For that reason they aren't
+   added to the list of supported LEDs.
