From b685004f8dea2daae0306edcd358ed7de751aee9 Mon Sep 17 00:00:00 2001 From: Ryan Mallon Date: Wed, 16 Apr 2008 02:56:35 +0100 Subject: [ARM] 4988/1: Add GPIO lib support to the EP93xx Adds support for the generic GPIO lib to the EP93xx family. The gpio handling code has been moved from core.c to a new file called gpio.c. The GPIO based IRQ code has not been changed.
