From 2795573a8c9c62db7b4bcf4bddf54d73b6ae61d3 Mon Sep 17 00:00:00 2001 From: Bin Meng Date: Fri, 12 Dec 2014 21:05:23 +0800 Subject: x86: ich6-gpio: Move setup_pch_gpios() to board support codes Movie setup_pch_gpios() in the ich6-gpio driver to the board support codes, so that the driver does not need to know any platform specific stuff (ie: include the platform specifc chipset header file).
