From e967f77d9818df884bdffb3e801eb12e0fd52b1c Mon Sep 17 00:00:00 2001 From: Denis Turischev Date: Sun, 13 Mar 2011 17:28:59 +0200 Subject: [PATCH] mfd: Add Tunnel Creek support to lpc_sch Intel Poulsbo SCH and Tunnel Creek provide almost the same LPC interface. Use the same driver for both devices while storing PCI ID to distinguish between platforms to apply plarform related quirks.
