From b71eec3129c2626bfb1e98141b317d958e3cf384 Mon Sep 17 00:00:00 2001 From: Bin Meng Date: Wed, 17 Dec 2014 15:50:38 +0800 Subject: x86: ich6-gpio: Add Intel Tunnel Creek GPIO support Intel Tunnel Creek GPIO register block is compatible with current ich6-gpio driver, except the offset and content of GPIO block base address register in the LPC PCI configuration space are different. Use u16 instead of u32 to store the 16-bit I/O address of the GPIO registers so that it could support both Ivybridge and Tunnel Creek.
