From 208cd822a19e683bc890f6708786f2420e172d76 Mon Sep 17 00:00:00 2001 From: Punit Agrawal Date: Tue, 29 Jul 2014 11:50:50 +0100 Subject: thermal: trace: Trace when temperature is above a trip point Create a new event to trace when the temperature is above a trip point. Use the trace-point when handling non-critical and critical trip pionts.
