From c4982887cacf2122bc256e901598b58caf4a34be Mon Sep 17 00:00:00 2001 From: Lennert Buytenhek Date: Fri, 24 Jun 2005 20:54:35 +0100 Subject: [PATCH] ARM: 2744/1: ixp2000 gpio irq support Patch from Lennert Buytenhek This patch cleans up the ixp2000 gpio irq code and implements the set_irq_type method for gpio irqs so that users can select for which events (falling edge/rising edge/level low/level high) on the gpio pin they want the corresponding gpio irq to be triggered.
