From e838ff8119a2aee621d4326f5899b8f4cdae40ac Mon Sep 17 00:00:00 2001 From: Ranganath Krishnan Date: Fri, 23 Aug 2013 11:08:23 -0500 Subject: thermal: ti-soc-thermal: Ensure to compute thermal trend Workaround to compute thermal trend even when update interval is not set. This patch will ensure to compute the thermal trend when bandgap counter delay is not set.
