From 25735d10ba477d5128b1e5ccef42062bea429075 Mon Sep 17 00:00:00 2001 From: Milan Svoboda Date: Wed, 21 Mar 2007 14:04:08 +0100 Subject: [ARM] 4275/1: generic gpio layer for ixp4xx This patch brings generic gpio layer support to ixp4xx. It creates functions needed for gpio->irq and irq->gpio translation. It expects and initial value to be passed to gpio_direction_output() which has been introduced by commit 28735a7253a6c24364765e80a5428b4a151fccc2 in Linus git tree. Generic gpio layer is going to be used by pxa2xx_udc driver.
