[OpenWrt-Devel] [PATCH 3/6] [kernel] ath79: new functions for passing GPIO data to wireless module

[Michal Cieslakiewicz]

From: Michal Cieslakiewicz <michal.cieslakiewicz at wp.pl>

Patch provides functions for passing additional platform data
(WLAN LED name and GPIO buttons information) to Atheros wireless module.

Signed-off-by: Michal Cieslakiewicz <michal.cieslakiewicz at wp.pl>
