From 8bf026177000c5bb566cafe2528a96f8380f38bd Mon Sep 17 00:00:00 2001 From: Alek Du Date: Tue, 22 Sep 2009 16:46:36 -0700 Subject: gpio: add Intel Moorestown Platform Langwell chip gpio driver The Langwell chip is the IO hub for Intel Moorestown platform which has a 64-pin gpio block device inside. It is exposed as a dedicated PCI device. We use it to control outside peripheral as well as to do IRQ demuxing. The gpio block uses MSI to send level type interrupt to IOAPIC.
