Peter Anvin" Message-Id: <200710161341.18609.florian.fainelli@telecomint.eu> Content-Type: Multipart/Mixed; boundary="Boundary-00=_eNKFHh68opwyC+p" Sender: linux-kernel-owner@vger.kernel.org X-Mailing-List: linux-kernel@vger.kernel.org Content-Length: 2549 Lines: 87 This is a multi-part message in MIME format. --Boundary-00=_eNKFHh68opwyC+p Content-Type: text/plain; charset="utf-8" Content-Transfer-Encoding: 7bit Content-Disposition: inline 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.
