[PATCH 5/7] ARM: shmobile: bockw-reference: Use falling edge IRQ for LAN9221

Laurent Pinchart laurent.pinchart+renesas at ideasonboard.com
Sat Nov 9 07:23:57 EST 2013


The device is configured to generate an active-low interrupt signal that
is automatically deasserted without requiring any action from the host.
Configure the IRQ to trigger on falling edge.
