From 77e337c6e23e3b9d22e09ffec202a80f755a54c2 Mon Sep 17 00:00:00 2001 From: Aaron Lu Date: Wed, 3 Sep 2014 15:13:02 +0800 Subject: Thermal: introduce INT3402 thermal driver ACPI INT3402 device object could report temperature for the memory module. To expose such information to user space, a thermal zone device is registered for it so that the thermal sysfs interface can expose such information for userspace to use.
