From a608295935d237bdbe95eefdba1e3fa40676df31 Mon Sep 17 00:00:00 2001 From: Florian Fainelli Date: Wed, 30 Jan 2008 13:33:35 +0100 Subject: [PATCH] x86: add generic GPIO support to x86 This patch adds the generic GPIO support to the x86 architecture. We do the same as for MIPS, we let the machine override the gpio callbacks and provide defaults one in mach-generic.
