From 1d09aaa6a325d55680506d585c7d5ee4744f5539 Mon Sep 17 00:00:00 2001 From: Mathias Nyman Date: Wed, 12 Dec 2012 17:42:38 +0200 Subject: gpio/lynxpoint: add chipset gpio driver. Add gpio support for Intel Lynxpoint chipset. Lynxpoint supports 94 gpio pins which can generate interrupts. Driver will fail requests for pins that are marked as owned by ACPI, or set in an alternate mode (non-gpio).
