From ce8be7785922de0ef497b20384425ed04f674f9d Mon Sep 17 00:00:00 2001 From: Lukasz Majewski Date: Mon, 8 Dec 2014 18:04:20 +0100 Subject: thermal: of: Extend of-thermal to export table of trip points This patch extends the of-thermal.c to export trip points for a given thermal zone. Thermal drivers should use of_thermal_get_trip_points() method to get pointer to table of thermal trip points.
