From bdf82b59c5dcf04bbdbd1938eefca14dd9cb44d3 Mon Sep 17 00:00:00 2001 From: Deepak Saxena Date: Mon, 29 Aug 2005 22:46:30 +0100 Subject: [ARM] 2836/1: Cleanup IXP4xx GPIO code Patch from Deepak Saxena This patch implements the set_irq_type() hooks for configuring GPIO IRQ type and updates all the platforms to use it instead of the gpio_line_config() function which is now used to configure input vs. output on the pins.
