From c55d62820efe3b847a21c78634356b5e4ec6d010 Mon Sep 17 00:00:00 2001 From: Srinivas Pandruvada Date: Wed, 28 Jan 2015 11:56:46 -0800 Subject: ACPI / LPAT: Common table processing functions Since LPAT table processing is also required for other thermal drivers, moved LPAT table related functions from intel PMIC driver (intel_pmic.c) to a stand alonge module with exported interfaces. In this way there will be no code duplication.
