| 2009-09-23 | gpio: add Intel Moorestown Platform Langwell chip gpio driver | Alek Du | |
| 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.
