[OpenWrt-Devel] [PATCH 7/7] ath79: WNR2000v3: change WPS button to interrupt-driven GPIO key

[Michal Cieslakiewicz]

WNR2000v3 has one button (WPS) connected to AR7241 GPIO directly.
This patch changes its servicing method from polling to IRQ.
All other buttons, connected to wireless chip GPIO pins, remain polled.
